Question Replacing 2x4 T12 layins with LED

I'm replacing 2 of these in someone's kitchen. The fixtures themselves are very old, so I was planning on replacing the whole fixture vs just re-wiring fixture to avoid ballast and led bulbs. There's a billion choices including buying separate troffers from the LED light themselves. Customer is concerned about if LED strip goes out, they cannot simple change light bulb. They would need a new fixture.

Recommendations? Experience? Thanks

PS. A 2nd question. How many lumens do you recommend? Currently 4x40watt T12s = >10K lumens. But I don't think I need to replace with 10K LED lumens.

In addition to specs for watts, lumens and color it seems the type (A,B,C)is more important than the other specs since the fixture is modified for only1 type. . Many advertisements don't list the type. If you put the wrong type in, my guess is the lamp won't light or it.will burn up or did the manufacturers make the fixture LED modification idiot proof. Maybe some electricians can chime in.

There are some kinds that can be tricky like ones that are single ended. They won't work with shunted tombstones. Ones that only hookup to both ends because they will work with shunted or non shunted tombstone are easiest (IMHO). Careful though there are ones that syt either double end or single end. They will usually only work with unshunted.

Thanks guys, but I actually want to replace the fixtures, as they're very old, rusty trim etc. So I was leaning towards an LED integrated fixture. The customer would like daylight temperature (5000K) with high lumen output. I'd say 8K or more. Can anyone recommend a good reliable brand? Thanks

I would have your client get a 5k and 3k color temp light bulb and try them in their kitchen. 5k has a very bright, harsh appearance. OK for a workshop but not everyone likes it in a kitchen.

I definitely agree with Pilot, 5K is really harsh, experiment first, maybe even check them out in a lighting showroom.
