Satco lamps come with a big bunch of labels in the box. I think it is a code requirement to label rewired fixtures also. Maybe in the UL listing?

And then what? I'd like to know what would actually happen. I suspect it wouldn't be very dramatic.

I would imagine the installer would then look at the bulb he took out, and read the label on the bulb that says LED, if he didn't when he took it out.

What if the owner took them out when they stopped working and didn't know?

In most situations LED bulbs are interchangeable with standard bulbs.

I mistakenly wired 347 volts directly to a fluorescent bulb once. It exploded.

Original installation had a remote slab mounted ballast for 4 bulbs that ran 4 separate single bulb lay in fixtures. PIA to make any changes so they wanted to install ballasts in every fixture and loose the remote ballast. I forgot to install one ballast and energized the bulb full voltage!

I read a sticker once when I was changing bulbs. Haven't bothered since and I'd sure be pissed if something blew up.

We keep the T8 ballasts in my neighbourhood. I get to change the ballasts down the road too. Money.

Anyway the cleaning lady changes the tubes. Calls me when they don't work.

I retrofitted a shop full of 8 foot fluorescents with 4 foot LED kits that included new tomb stones, brackets, and jumper wires. The lamps were single ended with no wires needed on the end tombstones. Only the center tombstones were connected to the 120 line that previously fed the ballast. I left the old ballasts in after cutting all the wires. Easy job, good profit. I can't remember the brand name of the kits but my supply house had them. So does Home Depot. They came with stickers to warn they were LED lamps.

Pretty sure it’d be dramatic to install a flo bulb into straight 120v. Hence the stickers. Code around here
