18.5" T8 LED tube for fluorescent replacement

This 18.5 inch T8 LED tube replaces 18 inch fluorescent lamps in existing fixtures with electronic ballasts. It delivers 950 lumens of cool white light while drawing only 11 watts at 120 volts. The tube suits utility lighting applications where a direct retrofit is required.

Sustained output over 36,000 hour rated life

The lamp is rated for 36,000 hours of operation, which equates to roughly 16 years at six hours of daily use. Light output remains stable across that span without the rapid lumen depreciation common in older fluorescent tubes. Consistent performance reduces the frequency of relamping in commercial or residential settings.

Low heat and silent operation at 11 watts

LED technology produces minimal heat compared with the 15 watt fluorescent equivalent, keeping fixture temperatures lower during continuous runs. The tube operates without the audible hum or flicker associated with magnetic ballasts. Its 1.22 inch diameter fits standard T8 sockets without altering airflow or clearance in the housing.

Questions about this item

How much heat and power does the 11 W tube draw when it runs all day?

It consumes 11 W at 120 V and produces much less heat than the 15 W fluorescent it replaces, so daily operation stays cool and efficient.

What fixture and ballast must I already have for this tube to work?

You need an 18.5-inch T8 or T12 fixture with an electronic ballast; the tube is designed as a direct plug-and-play replacement for that exact setup.

Will the 1.22-inch diameter tube fit in the older 18-inch fluorescent fixtures I am keeping?

Yes, the slim 1.22-inch diameter matches traditional 18-inch T8 tubes, so it slides into the same sockets without any modification.
