I replaced almost 30 fluorescent tubes with these and got rid of all my ballasts.Beautiful light, instant on and the hum of fluorescent lights is gone. No problems at all with any of the bulbs. Would buy again in a heartbeat if needed.

Have been ordering from Bee�s for a few years. Always excellent service and product.

great bulbs at a great price

by -

The best thing about these bulbs is the 230° beam angle. I installed them in shop light fixtures with white reflectors and they give a nice smooth light because the reflectors are actually illuminated. Re-wiring was trivial and took about 2 minutes per fixture.

I replaced all of our basement, garage & laundry room fluorescent tubes with these 4' LEDs. Installation was fairly easy, only got shocked once. The tubes provide good light for utility areas.

Put these in my garage because it was too cold for normal ones. Had to spend about 15 minutes removing the ballast first. they work great and its 20 degrees outside. no flickering any more either.
