Had a new vendor drop by today and give us some samples of some t8 led bulbs. Figured best place to try them out was at the house. Pretty quick retrofit and about the same brightness.
I just want to apologize, on behalf of electriciantalk.com, to those who clicked on this thread expecting free stuff. Haha What brand are they? Lumens? Cost? Energy usage?
Why do most of the crummy retrofit tubes not have a diffuser lens instead of a clear plastic one. Most of the ones I have seen are crummy at best. They need to be behind something opaque to make them bearable.
Those things out me out of a job. Had a steady relamp / ballast gig every 3-4 months. I retrofitted with what look to be the exact same tubes a couple of years ago. Never had another call back.
I put some of them in my laundry room. They are nice and quiet and I can't tell the difference in light output.
I think they are cheaper than changing a ballast and 3 lamps

They did say they came in a frosted/defused lens as well but since the fixture already has a diffuser you are better off with the clear. I guess if you just had some utility lights such as the one I put them in you could opt for the other lens option.
Which in lies the problem at the office, all the tombstones are shunted, so to retro-fit them with these bulbs you have to change out all the tombstones as well. No thanks
They sell the complete fixture but who knows what that costs. I think the time to re cooperate the cost of changing out all the fixtures in a large office would be at minimum a couple years. Not gonna take the time to calculate it.
Swapping to rapid start tombstones is the killer to me. I've been lucky with replacement tombstones fitting right the first time, until this week. I'm now looking for replacement fixtures for a dimming job because the tombstones are proprietary.
They are making a so called plug and play LED tube now that as long as the existing ballast is electronic it will drive the LED lamp cost is around 25 per tube.
