Is the lighting located in an area of rough service or environmental extremes?
Garage door openers, unheated/cooled utility rooms and outdoor workshops place extreme demands of lighting equipment. Vibrations that can break a light bulb filament and cold temperatures that can cause a fluorescent tube to flicker are of no consequence to LED lighting, making these replacements a fairly easy decision.
6.) Is the brightness critical to the application?
LEDs are directional by nature, so trying to meet a specific brightness expectation over a wide area is not the best use profil 3 of LED lamps. The current crop of standard fluorescent tubes or high-bay lighting will probably be more efficient for these applications.
7.) Are you trying to retrofit an existing lighting fixture to accommodate an LED replacement?
Most current lighting fixtures are designed to capture and reflect as much light as possible from conventional light sources that produce light from all 360 degrees. Because LEDs emit very directional light, there are often many compromises that must be made by manufacturers in order to make LEDs “work” for the greatest number of retrofits. When possible, instead of retrofit bulbs consider a “total package” LED lighting fixture that has been designed from the ground up to efficiently use LEDs.
