I’m no expert, not even a knife maker, but I replaced all of the 48” fluorescent bulbs in my laundry room and garage/shop with 48” LEDs. The LEDs came with a little, very easy to install (new receptacles) retrofit kit that allowed me to use the existing fixtures. The bulbs could handle 120 V AC directly, so the ballast on the fixtures could be discarded. The lighting is better, the LED bulbs are supposed to last quite a bit longer than the fluorescent bulbs, are environmentally safer, and use less electricity. I’ve also replaced a few of the ceiling spot lights in my house with direct replacement LED fixtures. There is usually a choice of light “colors” - cold, warm, etc.
I think that it has been at least four years without having to replace any. The bulbs were not inexpensive though. I’m not up on what configurations are available now, but would guess prices have come down. If you can get a complete and inexpensive replacement fixture, it might be worth a try. Good luck! Mike
