Overview
This 18 inch LED LED tube draws 5/8/10W and runs on line voltage once the ballast is removed. It puts out about 620 lumens of a field-selectable color temperature. It is built for illuminated sign cabinets, where even brightness across the face matters. Rated life is 50,000 hours, which means far fewer replacements.

Frequently Asked Questions
Q: Do I need to remove the ballast?
A: Yes. This tube runs on line voltage, so the existing fluorescent ballast is removed and the sockets are wired directly. Check the spec sheet for single-ended or double-ended wiring and use the lampholders it calls for.
