For the 1st time in over 100 years, lighting technology is dramatically changing and quickly. Before we know it the incandescent light bulb will cease to exist. Below are some Frequently asked questions to help you make an educated decision when working with Solid State Lighting.
L-E-D stands for Light Emitting Diode...Way too much information to condense into a paragraph so click here for more info
Without getting too complicated there are a few things to keep in mind. 1st and foremost is that fact that LED is still a relatively new technology. You can expect pricing to come down over time like anything else.
We are also not talking apples to apples here. LEDs and light bulbs are not the same thing although they both produce light. Contrary to an ordinary light bulb, LEDs require a sophisticated heat management system to dissipate the heat as well as lenses. If you were to use a normal light bulb it wouldn't have any of these feature but they would be built into the fixture you were using depending on the application.
This is also why many LED's are built straight into the fixtures and over time that trend will only continue, thus eventually when you go to buy a new lighting fixture the LEDs will be built in even at the residential level.
There is another reality about LED which is it's life span. Unlike a regular light bulb that will traditionally last 500 to 6000 hours on average, LED's last on average 50 000 to 100 000 which in any application is a bonus. Read here for more detail on LED life span.
One last reality is that because of the life span, manufacturers have no choice but to make a bit of money when they sell LED products. Think about it, 50 000 lamp life is 24 hrs a day 7 days a week for 5.7 years...
If your worried about your initial investment think of this. You’re doing your part to save the environment, your maintenance costs just dropped down to near zero and depending on your usage you will actually make money off of your investment in as little as 1 year! Don't believe it? Go to the Energy Savings Calculator on our Links page and enter in your current light bulb wattage and any LED replacement bulb or fixture and watch your mouth drop!
Glad you asked!

DMX is a communication protocol that is most commonly used in theatrical lighting. If you want to know the entire history of DMX with more technical detail, please click here
Now for those of you who aren't accomplished lighting designers and board operators (we highly recommend hiring one through our distribution network), here is a "DMX for Dummies" style document which you can look at by clicking here
Welcome to the lighting industry's version of the HD DVD vs Blue Ray (think VHS vs BETA for those not in the know...) The new battling protocols are called RDM (Remote Device Management) and ACN (Architecture for Controls Network). The turf war is well under way to see which of protocols wins and almost everyone has an opinion. Most manufacturers are waiting to see which one prevails but most will incorporate them in the short term for LARGE scale projects if one or the other is specified...It's gonna be interestesting to see who wins as both have there +/-'s...Stay tuned!

Why yes you have! DALI is short for " Digital Adressable Lighting Interface" and is another protocol finding it's way into the commercial lighting world. For a full explanation please click here

Yes they do! Most Electric companies are still studying the effects on their grids with LED technology, but they do offer grants and or rebates based on special inspections. All you have to do is contact your local Hydro-Electric company and they will refer you to the appropriate department. Our distribution partners would also be happy to assist & support to navigate this faily simple process. We have seen projects approved in as little as 48 hours!

Well, it's a fair question and one that does require a considerable amount of an explanation. As Lumileds, the manufacturing arm for LEDs by the Philips Corporation and maker of the Luxeon, rebel & K2 LEDs used in most of Acclaim's fixtures puts it...
"Philips Lumileds uses the Weibull distribution function, a universally-respected statistical technique, to predict the useful lifetimes of power LEDs based on experimental data. The Weibull function, developed in 1951 by Waloddi Weibull, has proved effective in reducing the amount of experimental work required - and therefore the costs and time involved to model the behavior of systems or populations containing large numbers of units. It has been applied successfully throughout many industries...."

You can drive LEDs with either a constant-voltage or constant-current design.
