Frequently Asked Questions

What company makes the LEDs in your fixtures?
LEDs are part of an overall electronic system within a fixture; we use LEDs from several different manufacturers in our fixtures, based on the application and electronic factors.

Can motion detectors and photocells be used with your fixtures?
Yes, but be sure to specify the input voltage for each fixture.

What happens when an LED light goes out?
LEDs, unlike lamps, do not just “go out”; they slowly dim over time. If an LED does not go on, that means there is no power to it – either there is no power getting to the fixture, or the power supply needs replacing (usually after many years of service).

I see most LED fixtures operate off 110 to 277 VAC input voltage – what about higher input voltages (440, 480)?
Most of our standard products operate at 110 to 277 VAC, but it is often possible to add a step-down transformer (at additional cost) to accommodate higher input voltages such as 440 and 480V.

Do LED fixtures operate well in cold temperatures?
Yes, LED fixtures operate very well in cold weather.

Do LED fixtures operate well in hot temperatures?
Hot ambient temperatures can reduce the life of any light source, and LEDs are no exception. However, since LEDs operate at much lower temperatures than most HID and traditional light sources, a well-designed LED fixture should outlast the traditional light source it is replacing.

Can LED fixtures be used with solar power?
Yes, LED fixtures can be driven by solar power.

My company/organization requires a specific payback period on all projects, what is the payback period for LED fixtures?
Payback period, or return on investment, varies by project with LED fixtures. Many factors contribute to LED fixture project payback. See the Project Analysis page for information to be factored into project payback calculations.

I was told I have to replace all the lights in my building at once, is this a good idea?
The advantage to replacing all lights is that pricing for installation and materials is lower on a per fixture basis (price breaks for larger quantities, electrical contractor completes job while all equipment is there to perform job, etc.) than for replacing lights in phases. On the other hand, replacing lights in phases may be a good idea when business interruption or budgets are a concern. Many customers choose to relight areas of a facility with the best return on investment first, and use savings from this first phase to help finance future phases, etc.

Can light from LED fixtures be dimmed?
Dimmability varies from fixture to fixture.

What about restrike time and LED fixtures?
LED Fixtures are instant on/instant off – there is no restrike time.

Can I get LED fixtures in different colors?
Most fixtures can be powder-coated for an additional cos
