Description
An on/off T8 LED tube with a built-in lithium emergency battery, made for wall-switched fluorescent retrofits. The battery keeps charging whether the wall switch is on or off, and a loss of supply switches the tube to emergency lighting within 1 second, for 90 minutes at 384 or 1,024 lumens.
It comes as a 2-foot 9W tube giving 998 lumens or a 4-foot 18W tube giving 2,319 lumens, in 4000K or 5000K with CRI 80. Ballast-bypass wiring is double-ended by default, with single-ended as an option, and it runs on 100–277V at 120+ lm/W. A test button and indicator lights for AC power, charging, malfunction and sensor operation are built in, along with an internally isolated driver and a battery rated for 800 charge/discharge cycles.
Rated IP44 with a 220° beam, ETL / cETLus listed, with a 50,000-hour rated life and a 5-year limited warranty.

Javier Navarro –
Great light bulbs I recommended them to my company in a drilling rig they have been working for a year non stop performing better than phillips saving a lot of money in ballasts and emergency ballasts and batteries, it is a great quality T8 lamp, The only down side is that they don’t come with instructions on how to set the sensor or the options with the small buttons
