Magnalight.com by Larson Electronics Announces Addition of Heavy Duty 150 Watt LED Boat Light


Kemp, Texas (PRWEB) February 29, 2012

The LED-BL-150W LED boat light from Magnalight.com produces 14,790 lumens of intense illumination yet uses far less power than comparable halogen or metal halide boat lights. Built for high output and durability, these LED boat lights also contain advanced pulse width modulation LED drivers that control heat, manage input current, and allow operators to optionally attach dimmers or external strobe controllers to provide precise control of light output and operating modes. These LED boat lights are ruggedly built, with aluminum housings and unbreakable polycarbonate lenses that offer IP68 rated waterproof protection and resistance to the damaging and corrosive effects of marine conditions. Thirty, 5 watt CREE LEDs paired with high efficiency optics produce a combined total of 14,790 lumens while consuming only 12 amps at 150 watts, making these LED boat lights far more efficient and powerful than comparable halogen boat lights. The LED-BL-150W LED boat light is equipped for versatile mounting with an adjustable trunnion style mounting platform that allows operators to securely attach these units to flat surfaces and adjust the fixture through 360 degrees of vertical movement once positioned in place without the use of tools. These LEDs lights are also capable of operating with a wide range of power sources and compatible with voltages ranging from 10 to 32 volts DC, making them ideal for boats where 12 and 24 volt electrical systems are most common. These high intensity boat lights will withstand vibrations, impacts, and extreme weather conditions that normal incandescent and glass bulb based lamps cannot, and are rated at 70% lumen retention after 50,000 hours of operation, making them far longer lived as well. The heavy duty construction and high power of the LED lights makes them ideal for a wide range of applications including boats, docks, marinas, shipyards, and even vehicles and ATVs.

Boaters left in the dark by old incandescent boat lights will love the LED-BL-150W with 14,790 lumens of bright white light with only a 12.5 amp draw on low voltage circuits, said Rob Bresnahan with Larson Electronics Magnalight.com. These ruggedly constructed lights with watertight construction can withstand the salt, water, vibration and abusive weather conditions so often found while boating and fishing.

Tips On Buying And Using LED Light Bulbs

By Joseph Reis

Green is good, and right now, energy efficient lighting is all the rage. With the looming phase-out of old-fashioned incandescent light bulbs in many developed countries, people are faced with choosing between a handful energy efficient forms of lighting – compact fluorescents (CFL) and light emitting diodes (LED). This article will help you make good decisions when buying residential LED light bulbs.

CFLs are good for now, but…

You have likely already adopted energy efficient compact fluorescents (CFL) as part of your effort to reduce your carbon footprint. While CFLs are energy efficient, they have drawbacks such as mercury and relatively short lifespan. Also, CFLs are not available in sizes that replace track light bulbs, such as MR16 and GU10. It is unlikely that CFLs will be available in these sizes.

CFLs have made giant inroads over the last couple of years. The low cost and high energy efficiency of CFLs have made them favorites with people replacing incandescent lights. According to the Energy Information Administration, a government agency, 9% of a household’s energy costs are related to lighting. People are genuinely concerned with lowering their energy consumption, and lighting is one of the easiest things a person can improve on. With worldwide support from mass-market retailers, governments, and citizens, energy efficient lighting is seeing a new dawn. While CFLs provide a good combination of efficiency and cost, there is an even better option on the horizon – LED light bulbs.

Introducing the next generation of ultra energy efficient light bulbs – LEDs

LED light bulbs are semiconductors, just like the chips in your computer. These semiconductors emit energy in the form of photons of light. LEDs have come a very long way since they were invented in the 1960s. You have seen LED lamps for decades in the form of indicator lights on electronic products. Now, these LED lamps light bulbs have evolved to the point produce enough light for household and commercial applications. LEDs are extremely energy efficient, and have lifetimes ranging from 50,000 hours to 100,000 hours. LED light bulbs are the perfect complement to your collection energy efficient lighting products.

Tips for Buying LEDs

There are several varieties of residential LED light bulbs on the market. Presently, LEDs best replace track lighting and flood lights, both of which take advantage of the directional nature of LED light. Below are some tips for buying LED light bulbs.

• The Basics

You want to find an LED bulb that produces a healthy amount of light, but at the lowest possible power consumption. A good metric that equalizes your search is “lumens per watt”. To derive this figure, simply divide the bulb’s number of watts into the number of lumens. Right now, a good LED bulb should have at least 40 lumens per watt, but preferably more.

The question is often asked about comparisons between normal light bulbs and LEDs. Here are some examples to guide you:

5-watt, 3 high power CREE LED, MR16 ~ 25-watt MR16 Halogen

5-watt, 3 high power CREE LED, E27 spot ~ 30-watt E27 spot Halogen

6-watt, 165 traditional LEDs, PAR38, ~ 50-watt PAR38 incandescent

• Lifetime of Bulb

Many manufacturers of LED bulbs claim lifetimes of 50,000 hours to 100,000 hours. The lifetime of an LED lamp is generally considered to be the point where the light output has declined to 70% of it’s initial output, measured in lumens. So, a 300 lumen LED bulb with a lifespan of 50,000 hours will have 210 lumens at the end of it’s lifetime. However, the lifetime of a bulb does not mean it is unusable, only that it’s light output has degraded to a certain point. The LED bulb may continue to be useful for several thousand hours past it’s stated lifetime. Unlike old-fashioned light bulbs, it is extremely rare for an LED light to simply burn out. Rather, it will gradually fade over time.

• Color

As a general rule, you should use warmer light indoors, and whiter light outdoors. A color temperature of 2500-4000 Kelvin works great indoors. You should use a bulb with a color temperature of 5000-7000 Kelvin outdoors, as the whiter light allows your eyes to see better at night.

White light in the 5000-7000 Kelvin range is also excellent for display cases, boutiques, artwork, or other settings where you need excellent color rendition.

• Type of LED lamp

LED light bulbs use one or more tiny semiconductor lamps to produce very focused light. Contrast this with normal light bulbs that generate light in all directions. LED lamps are currently available in two forms: traditional LEDs (typically 5mm), which are smaller, and high power LEDs. Light bulbs using traditional LEDs require a large number of LED lamps to produce sufficient light, whereas high power LED bulbs use one or more lamps to generate light.

In general, the more LEDs, the better the light dispersion. Always get LED bulbs with more than one LED. You will find that single LED bulbs produce a very conspicuous outline, similar to a halo. Unless you enjoy halos across your walls, it’s better to buy light bulbs with multiple LEDs.

Here are some common track light and flood light bulb types, and suggestions for the LED arrangements:

For track bulbs such as MR-type and GU-type, try to get bulbs with 3 high power LED lamps (preferably using CREE or Nichia lamps). Avoid buying track bulbs using an array of traditional LED lamps, as these are not as effective as high power lamps.

For flood light bulbs, such as PAR-type, you can find reasonably priced traditional LED arrangements. High-power LED flood lights produce good light, but are also very expensive. In my experience, a PAR bulb using 120 or more traditional LED lamps works just as good, at a fraction of the price.

• Cost and energy savings

LED bulbs have a higher upfront cost, but they pay for themselves several times over their lifetime. Because LEDs have lower power consumption and a very long lifetime, they are very energy efficient. Let’s take an example of a $45, 5-watt, 50,000 hour MR16 LED bulb. Let’s assume a constant electricity cost of $0.10 per kilowatt hour, and a 0.61 electrical grid CO2 output factor. Compared with a similar $8, 25-watt halogen MR16 bulb, the LED will save $255 and reduce carbon emissions by 1,345 pounds. Not bad for a light bulb.

As energy costs continue to rise, the cost savings and carbon reduction from using LEDs will become far more pronounced.

Buyer beware – LEDs cannot replace general illumination bulbs (yet)

Right now, there are plenty of options for LED light bulbs. And that’s a bit of a problem. Several sellers of LED bulbs claim their bulbs are powerful enough to replace general illumination bulbs such as incandescent and CFL. This is simply untrue. Many of these “replacement” bulbs cost nearly $100 and use over 10 watts of power. You are much better off using a $3.00, 10-watt CFL for now. However, keep an eye out for LED general illumination bulbs over the next few years, as they will become very competitive with normal light bulbs.

Start today with LEDs

As LED technology rapidly advances, you will see them replace all other forms of light bulbs, including CFLs. If you have track lights or flood lights, you can begin incorporating LED light bulbs right away. Remember, now is the time to take steps to save energy and money. Your wallet and the planet will both thank you.

Energy Saving Light Bulbs – Light Up The World

At first there’s darkness… but then Thomas Alva Edison conceived essentially the most excellent version of an incandescent light bulb. Thomas. Edison’s accomplishment is definitely credited to his creation of a complete and efficient scheme of electrical lighting prduct.

Next there’s light.

The actual technology of the incandescent bulb is credited to around 20 inventors. Based on historians Paul Israel and Robert Friedel, there are actually three major reasons why Mr. Edison’s design came to be the most popular:

1.Edison implemented an incredibly successful incandescent (heat driving light emission) components.

2.He was indeed able to attain a higher vacuum than the others.

3.He also made the circulation of power from the centralized resource economically viable by introducing increased amount of resistance.

From the launch of the electric light bulb on the market, we have seen countless transformations to the basic electric device. Technology have developed over time and nowadays there are number of bulb for us buyer to pick from and more recently bulbs are becoming even more eco-friendly with energy saving light bulbs leading the way.

Let us learn more about energy saving light bulbs.

We have typically known that light bulbs are the same shape as a dome. Consequently, came the first generation of energy saving light bulbs. Have you observed their odd forms? In fact, at first, energy saving light bulbs are just the same as the fluorescent tubes which are bent and strangely designed but are designed to easily fit in your standard light fitting. After many years of alteration and improvements, the dome shaped designs made a comeback. Brands have began to go back to the basics, thus presently, energy saving light bulbs look exactly like your standard dome or onion shaped light bulb.

As their label means, eco light bulbs were primarily designed so users can save on power consumption and ultimately minimize their electricity bills. With the ongoing economic situation, every single penny you can save is of great worth. Research shows that lighting accounts for the 10-15% of a regular home’s electrical power bill, and by using energy saving light bulbs, we can potentially lessen this cost as much as 80% when used rather than regular light bulbs.

But how do we indeed save? Well, these kind of bulbs are designed to use up a lesser amount of energy than the regular incandescent light bulb. You can make use of a 25-watt energy saving light bulb as opposed to a 100-watt regular or traditional bulb, and take notice, this is without sacrificing the brightness. Certainly, you’ll not observe any difference in the standard of the amount of light.

Many might point out that they are priced higher than regular light bulbs, so how can we save? Energy saving light bulbs lasts for a longer time when compared to the standard bulbs, they could last 10 to 15 times longer! Many can even last 5-8 years. The initial price will more than pay for itself considering the financial savings you gain over the lengthy life of the bulb.

In addition to the money savings when utilizing an energy saving light bulbs, you are in addition saving the environment. Due to their low energy and power use, they normally have decreased carbon dioxide emission, consequently by simply using these types of bulbs, you are in fact doing your share to save mother nature.

At this time, maybe you have found the light? The advantages of using energy saving light bulbs as outlined above really should activate the switch for you to begin using these. Think of what you can do for the earth and of course pocket.

Illuminating the Great Outdoors with Energy-Saving Light Bulbs

“Electricity Prices Plummet,” The Wall Street Journal, August 12, 2009

Hey, is there a recession going on? This timely article details how slack demand for electricity in 2009 may lead to the first consecutive year decline in electricity use in the U.S. since 1950. Such news may tempt some consumers to relax an otherwise robust commitment to reducing home and business electricity consumption. Conservation and energy efficiency are hard work, and harder still to turn into regular habits, especially when energy costs are low.

However, with days growing shorter and nights growing longer as we head into autumn, lighting costs will be on the rise for consumers, even if rates per kilowatt hours are ticking down. Now may be the best time to make a switch to more efficient, energy-saving light bulbs to reduce energy consumption, but there is no need to get carried away. Instead, we suggest folks start slowly with a deliberate approach that targets fixtures that are lit most frequently and for the longest periods. This often leads our customers who want to reduce energy consumption outside.

Green Light Bulbs Reduce Energy Consumption

Exterior fixtures come in as many configurations as indoor lights and they mainly serve three purposes: security lighting, accent lighting and convenience lighting. In some cases, single fixtures perform double or even triple duty.

The greatest savings, in both dollars and reduced carbon emissions, are most easily realized by installing energy-saving light bulbs in any fixtures which are lit from dusk-to-dawn but aren’t controlled by a motion sensor. This could be a floodlight above the driveway or back deck or a pair of decorative sconces or lanterns straddling the front entrance. Post lights are commonly lit all night as well. If you’re like us, you get peace of mind knowing that these lights make the home look very much occupied while you sleep.

Choosing energy-saving light bulbs with the highest efficiency ratings for the amount of light desired will reduce energy consumption and have the greenest impact. Consider this comparison: on one hand, we have a traditional (incandescent) bulb and on the other, an energy-efficient bulb. At 60 watts and 850 lumens, the efficiency of an incandescent bulb would be only 14 lumens per watt, with an annual use of 2,920 hours (8 hours/day). The annual cost to light? – approximately $20, but with a CO2 emission level of about 349 lbs. Now take a 15 watt energy-efficient bulb. Even though it has a lower wattage and uses less energy, the output of light is the same. Lumens are less at 825, and efficiency has improved to 55 lumens per watt. The annual cost to light drops $15, and CO2 emissions are nearly three-fourths less.

$15 annual savings per socket is more than enough to upgrade to energy-saving light bulbs in order to reduce your energy consumption. Your energy efficiency investment will be paid back in less than one year. As for CO2 emissions, a 75% reduction won’t do your eco-conscience any harm.

For homes, Compact Fluorescent Lamps (CFLs) are a solid choice for dusk-to-dawn lighting scenarios. They’re available in a wide array of wattages, shapes (including decorative), sizes and colors and are typically designed to last 8,000 hours or more. One drawback of energy-saving light bulbs in an exterior setting is that they’re affected by ambient temperature. Our advice: if you live in a colder climate, look for lamps with “amalgam” technology for best performance or buy ones with the next higher incandescent watts equivalent (example: if you’re replacing a 60 watt incandescent, buy a CFL equivalent to a 75 watt bulb). Also if a fixture isn’t weather protected, be sure to select a bulb rated for use in a wet location.

Light Emitting Diode (LED) lamps are hitting the market at a rapid pace and are also worth considering for their superior ability to reduce energy consumption and extremely long life. Interestingly, LEDs don’t emit ultraviolet light and don’t attract insects. For an overnight fixture near a door, an LED would be a good alternative to a yellow bug lamp. Advice: insist on UL listed LEDs (not easy to find) for safety’s sake.

Energy-Saving Light Bulbs for Motion Sensors and Electronic Timers

For multiple reasons, energy-saving light bulbs, such as CFLs, are a poor choice for fixtures that light automatically by motion detection. These are typically used for security purposes but are also a feature of garage door openers. CFLs are not engineered to produce short bursts of light. Thus, a traditional incandescent bulb is a fine choice (and probably what’s in the fixture now). Advice: when the existing bulb burns out, consider a high-efficiency halogen lamp to reduce energy consumption. Currently, these energy-saving light bulbs are 30 to 40% more energy efficient than traditional incandescents. Expect these savings multiples to grow as lighting manufacturers continue to improve their halogen technology in anticipation of lighting efficiency requirements that go into effect in 2012.

As for LEDs, while they do reach maximum brightness instantly, they are still very pricey and thus not a good investment for the short bursts of light delivered by motion control sensors. Prices will come down as demand increases for energy-saving light bulbs. My advice: wait.

Some people rely on electronic timers to switch on exterior lights as darkness settles in. Again, CFLs aren’t suited for this application. In this application, where once on, the light may remain lit during overnight hours; an LED lamp, which generally works with electric eyes (check with the manufacturer) would be an excellent choice to reduce energy consumption and extend bulb life versus an incandescent bulb.

Fall’s the Time to Make the Switch to Energy-Efficient Exterior Light Bulbs

They say that the cheapest, cleanest kilowatt hour of electricity is the one that is never produced in the first place. As the shorter days of fall approach and your energy demands grow, put on your green glasses and look at the lighting fixtures outside your home. You’re almost certain to find opportunities to reduce energy consumption and live more lightly with energy-saving light bulbs.
