LED Tubes and Retrofit Kits

An LED lamp is simply a light-emitting diode that is assembled into a lamp (lamp length can be from 12" to 48") that produces white light when power is applied. An LED retrofit kit is the use of light-emitting diodes on a chip form with additional hardware like brackets, sockets, screws, and fasteners. Both LED Lamps and LED Retrofit Kits require a fixture to provide housing.

LED Luminaires

LED Luminaires are light emitting diodes housed in a fixture assembly presented as one whole product.  This one product includes all parts to distribute the light, protect the LEDs and connect to a power supply.  The power supply is the only additional piece required to produce light visible from the LED luminaire.
