Q:Can your products be used in damp/wet locations such as showers, soffits, etc?
A:"Wet" locations are defined as being exposed to non-climate controlled environments, wind driven rain and/or pressurized water, and condensing moisture.  "Damp" locations are defined as being exposed to non-climate controlled environments, minimal water exposure (few droplets), and being at least 7' from any potential standing water.  "Dry" locations are defined as less than 75% humidity and no water exposure. Please refer to the specific Product Spec Sheet to determine suitable operating environments.

Q: Does turning LED lighting on and off reduce lifetime?
A: No. Unlike incandescent and fluorescent lighting which will fail sooner when switched on and off more often, LED lighting is unaffected by how often it is switched on and off.

Q: How do you evaluate LED products?
A: Lumen output is only part of the story and can be misleading. To fully evaluate an LED product one needs to review the overall system efficiency, optical control, thermal management of the LEDs, and know at what point in time the fixture will reach 30 percent lumen depreciation. Products with good optical efficiency and thermal management will be able to deliver more lumens, on average, than traditional HID products. As the Department of Energy concluded in its Solid-State Lighting Commercial Product Testing Program: "Until the field of SSL technologies and supporting knowledge matures, any claims regarding performance of SSL luminaires should be based on overall luminaire efficacy (i.e., from testing of the entire luminaire, including LEDs, drivers, heat sinks, optical lenses and housing), to avoid misleading buyers and causing long-term damage to the SSL market."

Q: How does ambient temperature affect LED efficiency?
A: LED fixtures must be designed with junction temperature thermal management as a key component and use the correct LEDs. These products will then be robust enough to operate in most ambient temperature applications. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs.

Q: How long is 100,000 hours?
 A: Based on how long a fixture is illuminated per day, here's what 35,000 works out to:

Hours of Operation:  35,000 hours is:
 24 hours a day            4.0 years
 18 hours per day         5.3 years
 12 hours per day         8.0 years
 8 hours per day           12.0 years
 Q:Why are LEDs considered a GREEN technology?
 A:LEDs are environmentally friendly on many fronts. First, unlike HID (High Intensity Discharge) lamps LEDs contain NO mercury. In addition, some LED luminaires are RoHS (Restriction of Hazardous Substances) compliant and have been designed to provide more than a decade of near maintenance-free service. That means no re-lamping which means no waste.
 Assuming an HID fixture is re-lamped every two years, that’s five re-lamping cycles over a 10 year period.  Just imagine the benefits of choosing LED:
•    No concern over proper disposal (hopefully not simply thrown in a landfill) of old HID lamps containing harmful mercury.
•    No fuel used and the accompanying pollution to service those fixtures.
•    Greatly reduced potential for lane closures and other productivity and inconvenience-related costs associated with maintaining an HID system.
•    No natural resources lost to produce the replacement lamps that contain mercury.
•    No fuel used to move old-technology lamps from the factory (most likely overseas), to the distributor, to the contractor, to the job site.
 It’s important to keep in mind all the positive and powerful ripple effects that using LED technology can have on the environment.
