The commercial fishing industry is a demanding and dangerous arena where the risks are as high as the rewards. Often working around the clock and dealing with some of the worst weather conditions possible, commercial fishermen know well the importance of having reliable equipment that can stand up to the most abusive environments and continue operating without fail. With fishing operations very often taking place at night, illumination is one of those pieces of equipment that plays a critical role in safety and productivity that cannot be compromised on.
Commercial fishing vessels typically employ HID lighting systems in the form of high pressure sodium fixtures on their working decks. Powerful and efficient, these lighting systems have provided an adequate if only just so form of lighting that’s been the standard for many years. Since these vessels are far offshore for extended periods and must rely on self contained sources of power, efficiency and power are key factors in determining the type of lighting to be used, and to date HPS systems have been the most practical.
Two of the biggest drawbacks with HPS lighting on commercial fishing vessels have been their very poor light quality and sensitivity to moisture. The light produced by a HPS lamp has a distinct orange/reddish coloration that produces poor contrasting and color reproduction, reducing visual acuity for those on the deck. HPS bulbs also run very hot, and any exposure to moisture while in operation can easily cause a bulb to shatter or even violently explode, and given the fact that these vessels are exposed to some of the wettest marine conditions possible, happens all too often. Despite all this, HPS systems have remained popular due to the long lifespan of the bulbs and their very high luminous efficiency on the order of 120 lumens per watt. The less energy consumed by lighting, the less fuel that is burned during operations, improving the amount of time a vessel can remain at sea pulling in catches and reducing the costs associated with fuel.
Modern lighting technologies however are changing all this and providing some distinct advantages that many commercial fishing operators are already capitalizing upon. In particular, LED lighting systems have come to the fore that offer to provide the durability and efficiency a fishing vessel needs, and not only this, but provide much better performance than the old HPS systems they are replacing. To why this is let’s look at some stats regarding the two types of lighting and how they stack up against each other.
Lumens per watt produced by HPS systems averages 120 lumens per watt and is one of the most efficient forms of lighting available.
Color temperatures for HPS range around 200 Kelvin, putting them below incandescent bulbs and resulting in light output with a distinct reddish/orange coloration. HPS renders colors poorly, has poor contrasting qualities, and is generally used in applications where these qualities are not considered very important such as street and parking lot lighting applications.
Bulb life for HPS lamps average 20-40,000+ hours of operational life and are among the longest lived light sources available. However, HPS lamps are prone to a phenomena known as “cycling” wherein as the bulb ages, it becomes harder for the ballast to maintain a high enough voltage to keep the lamp lit. Eventually the voltage needed to keep the bulb lit exceeds the ballasts maximum capacity, and the bulb goes out. Once the bulb cools down less voltage is needed to relight it, and the lamp comes back on. This cycle continues until the bulb fails entirely.
HPS bulbs are quite fragile since they are made of glass and become extremely hot while in operation. As a result, they require extensive protection in the form of heavy duty housings, extensive sealing, and vibration absorbing mounting assemblies in order to survive the harsh conditions of the marine environment. As little as a single drop of water contacting a hot HPS bulb is enough to cause it to fail explosively. Because of this, HPS lighting systems require frequent maintenance and inspection to prevent failures.
LED lighting averages 60 to 100 lumens per watt and is tied with fluorescent lighting for second place in the efficiency category.
Color temperatures for LED lights varies according to configuration and can be set at a specific parameter. LEDs are available in 2700K, 4500K, 5000K, 6000K, and higher color temperatures. LEDs used for commercial fishing applications are typically in the 4500K to 6000K range and as a result produce a very sharp white colored light. Additionally, LEDs provide very good contrasting and good color rendering, making them well suited to applications where high visual acuity is critical.
LED lamp life averages 50,000+ hours, and many fixtures are available which can reach 100,000 hours of operating life. Additionally, as LEDs age they do not experience significant changes in operation. LEDs simply grow dimmer over time, and most manufacturers consider LEDs to have reached the end of their useful life when they drop to 70% of their original lumen output.
LEDs are a solid state form of lighting that is highly durable and versatile. They have no glass and so can’t fail from shattering, and don’t run hot and so aren’t as likely to fail from exposure to minor amounts of water. LEDs are highly resistant to damage form impacts and vibrations as well, making them well suited to applications where rough handling and abusive conditions are encountered.
LEDs offer commercial fishing operators a lighting alternative that can provide highly efficient operation coupled with far better light quality than HPS systems. The light they produce is whiter and more intense with better contrasting and color reproduction, which in turn helps with visual acuity during the performance of complex tasks. LED boat light fixtures are also far more durable than HID systems, and are able to withstand rough handling that would cause premature failure of an HPS fixture.
Overall speaking, commercial fishing operators can improve the safety and productivity on their decks without compromising on lighting efficiency. More reliable, better performing, and more durable, LED boat lights represent a step up from old style HPS systems that’s hard to beat.
LED floor lamps with dimmable features have transformed spaces, bringing in a dash of contemporary styling. In combination with other lighting, they help to improve the décor of living spaces. Dimmable LED floor lamps greatly help to tone down the intensity of the light. LEDs are some of the most energy efficient lighting units. Here is a closer look at the workings of a dimmable LED floor lamp.
Pulse width modulation dimming method
It is important to understand that despite the appearance of dim light, LEDs do not actually emit dimmer light. LEDs function in two modes – ON and OFF. So effectively, what is observed as dim light is actually light being emitted in pulses at alternating intervals. This pulsing of the light is controlled by the dimmer, which determines the intervals and the intensity of the pulsing.
Frequency of pulses designed to create the effect of continuous light to the naked eye
Pulsing light, should ideally appear as pulses of light broken up with intervals of darkness in between; more like a flickering lamp or wick. However, a flickering light is definitely not the ideal light for floor lamps. A floor lamp requires continuous light, therefore, PWM LEDs are designed to emit light in pulses at a high rate, which will create the effect of continuous light.
New look – Dimmable LED floor lamp
A perfect dimmable LED floor lamp offers a warm amber glow to transform the ambience of your room. The dimmable feature enables light to be adjusted to emit at levels ranging from bright task lighting to dim, soft, cosy tones. The exciting designs of dimmable floor lamps help to improve the aesthetics of interiors. The sleek and compact designs help to create wonderful lighting from stunning light accessories.
Working principle incorporates the Analog technique
Analog dimming technique is the underlying principle used to dim LED floor lamps. The forward current supplied to the LED bulb is controlled, and the linear power supply to the bulb causes the dimming effect. Due to the changes in temperature, the light emitted from low quality dimmable LED bulbs may lack the intensity, therefore it is important to choose dimmable LED bulbs of high quality.
Challenges for dimmable LEDs to flourish
Demands exist for LED manufacturers to develop dimmable LED bulbs. However, it needs to be borne in mind that users generally like to retain their fitments, and it becomes necessary for manufacturers to develop LED bulbs that can be retro fitted. Though the technology is relatively new, it has time and again been demonstrated to work with utmost efficiency. The demand for dimmable LED bulbs is increasing and the day is not far off when LED bulbs will reign over the lighting world with their designs, features, durability and savings in cost.
The digital age has also rendered in exciting possibilities for network controlled lighting and wireless controls. The main dimming methods are TRIAC dimming, PWM dimming, and linear dimming. It is time to illuminate in style and take the style to levels that exist in the most creative minds.
Many people have been hearing a lot about LEDs lately, like how they are used in TVs and light fixtures. Today, you can even purchase LED desk lamps. However, very few people actually know why LEDs are so important or what they really are. Fortunately, this article can provide you with all the information you need on LEDs and the desk lamps that use them.
LED stands for light emitting diode. They have been used for quite a long time to create small sources of light for a variety of uses, including art projects and small electronic devices. Today, they are used for many purposes, such as creating main source of light for rooms and work sites, and to create the brightness in televisions.
The great thing about LEDs is that they do not heat up in the same way that traditional bulbs do. If you have to spend a large period of time working under a lamp with a bulb, you will probably notice that it gets really hot. LEDs, however, do not produce much heat at all.
If you have a desk lamp that uses LEDs, you will not get hot working underneath it. This is great for long work or study sessions. Also, if you keep a plant near your lamp, you will not have to worry about the plant overheating and withering as a result.
LED lamps are also more energy efficient than traditional lamps that use bulbs. This means that they require less electricity to operate, so it is possible to save money on your electric bills by using them.
LED desk lamps are now available in a wide range of styles and colors. There are many highly compact and contemporary styles that will fit nearly anywhere, while still producing a very bright light. You can also get lamps which swivel and bend.
An LED can also be described as a light emitting diode and it is a product that is assembled into a lamp. It is particularly used for the purpose of lighting. These bulbs have a lifespan as well as an electrical efficiency that are several times greater than a normal incandescent lamp. These are also highly efficient when compared to a normal fluorescent lamp. Some important things that you must essentially learn about LED bulbs have been explained below:-
1. Are LEDs expensive?
Gone are those days when LEDs were expensive. As the demand of these bulbs in recent times has increased and also the processes of manufacturing has also streamlined, the costs have gone down significantly. The efficiency of these bulbs have also resulted in a lot of customer craziness. Everyone wants to get their hands on this one. It is one of the important things to remember.
2. Where can you use LED bulbs?
You can use these bulbs absolutely anywhere. There are many households that follow a guideline of dimension for a familiar shaped bulb. There are also many that have a bulky look to them. You can also find these light in spotlights, floodlights and other lighting formats. Other places include various designer formats such as various flat panels.
3. Wi-fi connection
Many LED bulbs are also connected to wireless internet. These can be operated through your smart phone. You can use this facility to switch the bulb on and off and this is a very efficient way to monitor and control your LED bulb.
4. Applications of LED lamps
These lamps can be used for both special and general purpose of lighting. These white light lamps have a long life expectancy and also high efficiency. These sources of LED are also compact and are able to offer a great amount of flexibility in designing the lighting features. This bulb by using the principle of color mixing can emit a very wide range of colors thus making it multi-purpose.
In recent times, there has been a lot of research as far as LED bulbs are concerned. You too can make good use of these bulbs. These can be used anywhere as they are multipurpose. Always make sure that the LED bulb you use is multipurpose and can serve all you needs and requirements with respect to your lighting. These can help you a lot in the long run.
Companies wanting to increase energy efficiency for the business will want to consider LED panel lights. These new lights can help businesses to be more energy efficient while still providing plenty of light to do business. These lamps are very long lasting and may not need to be replaced for many years.
A LED panel makes and efficient replacement for more traditional fluorescent tubes that are often used with suspended ceilings. The lamp can replace the panel that holds fluorescent tubes. The electrical draw of the LED systems is much less than the tubes. The panel will draw less electricity than one traditional sixty watt lamp.
The light provided by the LED lamp is full spectrum white light. With fluorescent lamps the spectra is not complete, thus some colors are not present. This can cause clothing and makeup to appear different colors. It can also cause eyestrain in some people. The full spectra light offered by the LED lamp is the same spectra as provided by the sun or a traditional lights. The result is much less eyestrain.
While businesses will pay significantly more for the initial installation cost of LED lighting, they will recover the cost through the years with lower power bills and less maintenance costs as the panels will not need to be replaced as often as other types of lighting. LED lamps can help to reduce global use or natural resources.
A close inspection of the panels may seem somewhat strange to persons used to other types of lighting. The panels are made of many individual lights. Each of the lights add together to provide a bright even lighting for the room. LED lighting is also effective when used outside as well as inside the business.
LED panels offer durable lights that are an excellent form of energy savings. They can be used in business establishments as well as public buildings. Power requirements are much lower and the panels will last for many years, lowering both maintenance and energy costs.
Adding security lighting is the number one step homeowners can take to protect their property from unwanted intruders. Statistics show that burglars bypass targets that are difficult to access without being noticed. A well-designed security lighting system can make would-be robbers think again before approaching your property. This guide will show you how to create an effective, low-cost LED security lighting system for your home or business. vivo v15 pro
Use many smaller lights rather than fewer, more powerful lights
Big, powerful flood lights are good for open spaces, but can sometimes leave shadows if there are obstacles on your property like buildings and trees. Using a combination of LED flood lights, area lights and wall packs will reduce shadows and blind spots that intruders can use to hide.
Keep lights high and out of reach
It’s important to make it difficult for burglars to tamper with your security system. Many thieves will plan heists for several weeks and finding a way to disable security lights is often a top priority. Even the best security lighting can be rendered useless if an intruder is able to incapacitate the system. Keeping lights high and out of reach will make it difficult for your system to be tampered with. Placing lights high will also soften the light for a pleasant look and increased coverage.
Use Motion Detector Lights
Motion detector lights are an effective way to scare off intruders. Burglars will be on edge during a robbery and having a light flick on as they walk by is often times enough to scare them away. A good combination of LED spotlights and motion detector lights will work to keep intruders off of your property and scare away those who choose to enter.

Video Walls Abu Dhabi companies including the Audio Visual Solution providers implements LG Video Wall & Digital Signage.
Focus on Entrances and Exits
Most criminals seek out targets that can be accessed at night without being seen. Ensuring excellent light coverage at all entrances and exits will deter criminals from planning a robbery at your property.
Efficiency: LED lights offer exceptional efficiency and are more cost-effective in the long run. An LED light fixture will use 90% less electricity than an equivalent incandescent. This is also important if your security lights are forced to run on a backup generator. Less energy draw means your lights will last longer on a limited supply of power.
Longevity: A quality LED bulb can have a useful life of 25,000 hours or more. This is more than 25 times long than traditional light bulbs. Safety: LEDs run cooler than conventional light sources and are therefore less of a fire hazard. Durability: LEDs lack filaments or glass enclosures, making them more durable than traditional alternatives. Same colors as traditional bulbs: LEDs can achieve the same colors as traditional bulbs. Use the Kelvin temperature color scale below to help identify the hue a bulb will produce.
THE COLORED LED AND WHITE LED MARKETS
Whereas the market for colored (Red, Green, Blue) RGB LEDs is well established, the market for white LEDs is still growing. Why? When you think of industries that still rely on white, non-LED lighting, such as televisions, automotive manufacturers, computer monitors, notebook computers, LCD backlights, etc., you can understand the push to become the leader in white LED manufacturing. Many people are surprised that a business would pass up a revenue generating opportunity that converting a home or business to LED would create. However, just because replacement white LED bulbs and retrofits are finally on the market, does not mean that they should be on your immediate shopping list. In very simple terms, the market for colored and color-changing LEDs is mature. While engineers are still finding ways to make them brighter and more efficient, the holy grail of the LED industry is in developing volume production of high-efficiency, high-brightness white LEDs. www.nyccarservice.us offers Airport Car Service, Limousine Service and Taxi Service in Connecticut, New Jersey, Pennsylvania, Long Island, Westchester and Upstate New York.

It may be easier to think of colored LEDs (RGB) and white LEDs in terms of another industry: Automotive. RGB LEDs are like the internal combustion engine: Reliable, abundant, easy to use and manufacture, and fairly well developed in terms of the potential for new or breakthrough technologies. There are lots on manufacturers and each has their own set of patents and “tricks of the trade” to help give themselves some marketing leverage over the competition. White LEDs are like the alternative energy industry for transportation: Quite varied, still relatively “new”, still needing to be market proven, more expensive, more challenging to manage. There are many manufacturers, each using a different technology or combination of technologies to achieve what they believe is the “the next big thing.” Following this analogy, RGB LEDs are mature enough to compete on cost alone and the drop in costs is what fuels new applications for colored LEDs that had not been thought of previously. White LEDs, on the other hand are still developing technically and should not be shopped based on cost alone. The need for quality and longevity is what fuels the further research and development into white LEDs. starlighting neon strip lights
11 THINGS TO CONSIDER IN DETERMINING LED UPGRADES
Because there are so many variables that need to be considered, making a quick and easy recommendation about transitioning to white LEDs is not possible. To get a jump start on the future, consider every lighting source in each room and establish what it’s primary purpose is. Once you have done this, review the following items to help determine where on the priority purchase-list each replacement should be. Here are a few general guidelines to help you determine if an LED upgrade is the right choice for you:
1.) Is the lighting located in a home where the primary resident is older or has mobility issues?
If the LED replacement produces adequate light levels, LED alternatives are perfect for use in homes where safety is a top priority. Knowing that an ill or older person will not need to change a burned-out light bulb again can provide peace-of-mind.
2.) Is initial cost a primary factor in determining if you are going to upgrade?
The current nature of the white LED market means that prices are still relatively high, especially compared to traditional lighting. Being an early adopter means paying a premium; are you comfortable with knowing you could have paid less for the same technology if you had waited?
3.) Is the light located in bright daytime sunlight or an area of high heat?
High levels of heat will noticeably shorten the lifespan of any LED, especially white LEDs. When considering LEDs, try to ensure that both the fixture and the location allow for adequate passive cooling to avoid color-shift and longevity issues. This is a much bigger concern when considering retrofit bulbs versus considering a “total package” LED fixture and lamp.
4.) Are you needing to reduce the heat output from a traditional light source?
In bathrooms, laundry rooms and small spaces, conventional lighting can produce uncomfortable heat. LED lighting is great for these areas because they produce no heat and because affordably illuminating smaller areas with LEDs presents much less of a challenge.
5.) Is the lighting located in an area of rough service or environmental extremes?
Garage door openers, unheated/cooled utility rooms and outdoor workshops place extreme demands of lighting equipment. Vibrations that can break a light bulb filament and cold temperatures that can cause a fluorescent tube to flicker are of no consequence to LED lighting, making these replacements a fairly easy decision.
6.) Is the brightness critical to the application?
LEDs are directional by nature, so trying to meet a specific brightness expectation over a wide area is not the best use of LED lamps. The current crop of standard fluorescent tubes or high-bay lighting will probably be more efficient for these applications.
7.) Are you trying to retrofit an existing lighting fixture to accommodate an LED replacement?
Most current lighting fixtures are designed to capture and reflect as much light as possible from conventional light sources that produce light from all 360 degrees. Because LEDs emit very directional light, there are often many compromises that must be made by manufacturers in order to make LEDs “work” for the greatest number of retrofits. When possible, instead of retrofit bulbs consider a “total package” LED lighting fixture that has been designed from the ground up to efficiently use LEDs.
8.) Is the light output and quality of the LED version acceptable compared to your existing lighting?
With the variety of lighting technology available (incandescent, fluorescent, LED, etc.) the only way to get an accurate idea of how the lighting will perform is to compare the light output or lumen and color temperature specifications instead of the wattage as is typical of most of us raised with traditional lighting in the home. The US Department of Energy has devised a standardized “lighting facts” label similar in concept to the nutrition label found on foods, to help consumers compare lighting.
9.) Are the bulbs you’re considering replacing difficult to access or reach?
If they are, LED replacements are great candidates because once they are changed, you will likely never have to change them again since LEDs do not “burn out” like a conventional bulb.
10.) Are you replacing all the light bulbs in a particular area or just a single bulb?
Unless you know the color temperature of all the lighting in the room, try to be consistent in whatever lighting technology you choose. For example, if your room uses primarily halogen lighting, it is likely a warm color temperature and changing a single reading lamp to LED with a cooler lighting temperature will not only be noticeable, but may also be distracting.
11.) Does the energy savings and/or return on investment (ROI) make it worthwhile at this point?Prepare an energy audit using free web calculators to determine how much money you will save on energy and what the potential return on investment is. Just enter your energy rates, the total wattage of your conventional lighting and the total wattage of the LED lighting that you are considering and the calculator will tell you exactly how much money each technology will cost you per year.
As you can see, every lighting situation should be considered individually against the above checklist. Doing so will help you to determine LED upgrade plans that fit within both your budget and your expectations. In general, LED lighting will continue to improve in both output and efficiency every year similar to the way the personal computer market has evolved. What could be considered a “middle of the road” LED lamp today, was very likely considered a premium product a year or two ago. Prioritizing your LED lighting purchases so that the basics are covered first and delaying your more demanding lighting requirements as the technology improves will ensure a comfortable transition to tomorrows lighting technology.
