Very fast shipping and delivery. Have now tried these in 3 types T8s from Lowe's, Rona and Home Depot purchased over the years. Worked fine in all three types. Also ran across several sets of T12 did not even know we had in furnace room, removed ballasts, bingo was even brighter in T12. So if 50000 hrs is even close will be great upgrade. Will get back to you 2034.

Have placed these now in 3 types lighting. 1-Utilitech 50-1/2-in White Ceiling Fluorescent Light ENERGY STAR T8, worked fine. Litton T8 worked fine. 3- Very old no brand T12, removed ballast bingo worked fine. Impressed

ce n'était pas la même chose que ma commande précédente mais j'ai été agréablement surpris plus facile a insérer dans les connecteurs par ce que un peu flexible éclairage à 300 degré super je recommande

Absolutely love these. Replaced lamps in basement of house. Rip those old ballasts right out and wire direct :). Replaced old Mercury lamp fixtures in garage with 4 bay tube fixtures. Instant on, no flicker and I can see stuff now.

Installed one set with existing ballast and the ballast blew in about four hours. One light was dimmer, anyway. Took out the ballast and now the light is brighter than with the flourescents and whiter too! Will now take out the ballasts in all the other fixtures before installing the new bulbs.

Wow! I'm impressed with these LED neon replacement. Light is extremely bright and even. They were plug & play in my case. Some of my fixtures hold 2 tubes, to the naked eye one of the tubes seem slightly dimmer than the other one for some reason. I hope they will last a long time.
