Relamped my PL-T 32w Lithonia fixture early in the evening; old lamp went Mercury-starved.

Reset the Intermatic wall timer (replaced the battery, reprogrammed) for our garage lights, and swapped out an EOL 16W Feit LED for an "Outdoor" variant of the Philips Marathon. With the frigid weather, the lamp was very hesitant to even start up.

Also turned the 70w OVZ back on, running it four hours a night now, at minimum. First startup since late fall at this point now...

What's the worst LED fixture you have seen?
The worst I have seen is one at the beach, it was one of those ultra-cheap Ebay Corn-On-The-COB LED floodlights. The problem with it is that it has loads of glare, and had a very purple light, enough to make me think they used purple LEDs!
Could be from Amazon too, a lot of the stuff eBay sells are also sold on Amazon. Also, the phosphor probably faded away causing the light to turn purple.

What I’ve noticed in new construction, is that they commonly have Satco light bulbs installed when it is built, rather than GE, Sylvania, or Philips, even though some use faux Westinghouse, and in some cases the actual big three. I just toured a new construction this week and all the bulbs in the house were SATCO LED’s. All of them, and even in the 2000s I often saw videos of people removing satco bulbs when burned out (satco isn’t even available at all stores, most big box stores don’t even carry satco), so those were likely majorly installed by builders. I also went to a house where I saw satco bulbs (and I’ve seen some arc), and the house was full of them, the bathroom lights had clear bulbs and the bare bulb light and flushmounts I believe had the frosted version. Also, when I watch Lex’s dirty maintenance show, and he changes a bulb, I notice that some look like satco lamps, especially IF A19’s and candelabra bulbs.

Has anyone else been noticing this? Why is satco of all companies likely the most common light bulb choice for builders. Satco never even made bulbs, they only distribute bulbs and another company makes them for Satco. Whatever company who makes satco bulbs makes a lot of bulbs for different companies as well, like Halco and some other ones. A lot of the other “60W 130V 2500 hour” incandescent bulbs for example were made by the same company who makes the satco ones, with the same “LR58060” on the base. It also seems like many new construction pre-2020 were built with incandescents from satco or whatever and they put in the 130V ones for some reason with the C-9 filament to avoid the ban.

Asperger’s here. Officially diagnosed in the 7th grade. Probably explains my obsession with lighting and other electronics.

In my experience, the newer stamped etches tend to hold up pretty good. I have no problem when I am cleaning newer lamps. However, pre-1990s GE lamps do give me trouble. I’m not sure if they were always like this, but those etches wipe off CLEAN.

Yeah I had a feeling, I have no idea what impedance they are. 14W needs 275 ohms, 20W needs 240 ohms (ideally), that is kind of a big difference. 275 ohms could underdrive this lamp 20%. I assume it is somewhere in the middle.

It is good to note that the more generic “14-20W” preheat fluorescent reactor ballasts have a tendency to underpower F20T12 tubes and 8 inch 22W circline fluorescent lamps.
