I ran across a company last week called MaxLite. They had some extremely cool new lighting products that could be very applicable to the industrial and commercial electrical supplies market. I want to say upfront that I have not seen any of these products in a working environment, but I have seen the products work in a demo situation.
First, Maxlite has a high lumen CFL (compact fluorescent) for use as a field replacement for metal halide lamps all the way up to 400w (yes, 400w!). How it works is you replace the 175, 250, or 400w HID lamp with the high lumen CFL. The CFL typically seems to run about half the watts as the HID lamp. You bypass the HID ballast inside the ballast housing and, BAM, you have cut your watts in half without replacing the fixture.
Seems to good to be true huh? It seems very intriguing but there are a few things to consider. First, the lamp life is rated around 10,000 hrs. This is pretty low compared to HID or the other option of replacing the entire fixture with 46,000hr T8’s. Also the temperature rating is around 100 or 120 deg F which will be an issue in some areas and applications.
They did a very nice design with an integral heatsink and cooling fan, but be sure to consider the worst case temperature when looking at this. I think this could be a viable option for some circumstances, just be sure to look at all the application angles. T8 and T5 linear high bays or even 320w metal halide with pulse start will probably be a better choice for most applications, but this could be a fit for some.
They also have some other neat products, LED PAR replacements, LED light bars and my favorite…… a 2×4 LED lay-in fixture. This is the first LED 2×4 I have personally seen that works. It is not a bunch of LED’s formed to fit in T8 lamp sockets like some others have tried, it is an actual flat array of LED’s. Also, the profile is very, very slim, which is great for retrofit applications. The light output seemed adequate and the color seemed fine too.
The price is up there for the 2×4 and also the 2×2 (yes, they have a 2×2). They are probably selling in the field for around $600 for a 2×4. I’m not sure how many will be sold at that price, but it is an interesting option for those that are hooked on LED’s. Be sure to check them out or call your local lighting distributor for info.

The Leviton Decora Dimmable CFL and Incandescent Sureslide Dimmer can be used to control 300W-120VAC CFL and 600W-120VAC Incandescent, 60Hz, single pole and 3-way. It features an auto mode that can detect whether a lamp is an incandescent or dimmable CFL, determine low-end dimming capabilities and adjust dimmer range accordingly. The dimmer is UL Listed and CSA Certified.
The Attractive Decora styling coordinates perfectly with Leviton’s complete line Decora wiring devices. It fits easily into a standard wallbox and is suitable for multi-gang installations. Compatible with Decora screwless and Decora standard designer wallplates. Read more »

Home Controls is very excited to announce the addition of Xantech as one of our product lines. Since 1969, Xantech Corporation has designed, engineered and manufactured a multitude of innovative custom home control devices, from the IR receiver to high definition video distribution. Today Xantech continues to provide the products and technology needed to exceed the standards of even the most demanding custom home systems.
To purchase the perfect IR system from Xantech, simply follow these three steps:
Step 1: Choose the right IR receiver. What type of TV/Video Display or just Video Display technology is in the system?
- Plasma Proof IR Receivers: Use when Plasma Displays, direct sunlight or compact fluorescent lights are present. Plasma displays emit infrared light that interferes with IR controls. Xantech’s patented Plasma Proof IR Receivers eliminate this interference.
- LCD/CFL Proof IR Receivers: Use when LCD Displays, direct sunlight or compact fluorescent lights are present. LCD displays emit light wavelengths that interfere with IR carrier frequencies. Xantech’s exclusive frequency range adjustment eliminated this problem.
- Standard IR Receivers: The most commonly used IR receivers. Work great with DLP, standard CRT video and rear-projection displays.
Step 2: Select the right IR receiver style. Xantech has a variety of receiver styles to choose from:
- 291 Series Hidden Link Shelf Top
- 490 Series Micro Link Peephole style
- 480 Series Surface Mount Dinky Link
Step 3: Choose the right IR Receiver Kit. Home Controls offers several of the most popular kits. Check them out here.

LED lighting is becoming increasingly popular in the gas station c-store industry. This is not only due to the lower energy consumption of the LED lamps, but the new lighting also makes the beverages in the coolers more visually appealing!
OSRAM Opto Semiconductors recently released their findings from a study on the life-cycle assessment (LCA) of LED lamps. Here is a summary of their findings.
LED life-cycle assessment
Light Emitting Diodes are among the most energy-efficient light sources available on the market. LED lamps are already today more than five times more efficient than incandescent lamps and future technical achievements offer additional potential for the coming years.
At present, artificial lighting accounts for around19% of global electricity consumption – that corresponds to 2.4% of worldwide primary energy consumption. 70% of the energy used for artificial lighting is consumed by lamps for which there are more energy-efficient alternatives. Simply replacing conventional light sources with LEDs would theoretically halve global electricity consumption for lighting. The potential savings are therefore enormous.
An OSRAM study monitored the life cycle of an LED and an LED lamp. It´s outcome made it clear – LED lamps need less than 2% of their energy consumption for their manufacture – over 98% are used for their task: illuminating the world.
