This 18 watt LED T8 replaces traditional 32 watt fluorescent T8 bulbs and operates directly off the existing instant start or program rapid start ballast.
A quality glass encasing protects against yellowing and brittleness over the 50,000 hour life of the tube.
The integrated driver makes for easy installation and allows the fixture to keep its certification without any additional wiring.
This is a DLC rated lamp.
See the document below for complete specifications, including lumen output for low, normal and high ballast factor ballasts.
