Is it firm enough to sit down?  Are you comfortable to sit at this sofa?

These effects are often related to the pulsating blood just behind the eyes - after the sharp light cut off it has the most noticeable impact. Hard to judge what is normal and what abnormal, but if really excessive and mainly if it start to appear suddenly, without any normal explanation for abnormal heart activity (like ongoing demanding physical activity,...), it could be an indication of blood flow related problems (pressure, restriction build up), mainly if you are aging (when the cardiovascular problems become common) so maybe good to mention it to your doctor during checkup, what he thinks about it.

If they have any good condition Cooper Rma hoods, I would love one for my incomplete Cooper Rma in 100 MH.

It is borderline okay, because usually a PL-S lamp has a capacitor inside (somewhere about 4700pf) *about* in the range of what to be expected for simple electronic ballast resonant capacitor. More, there are non-standard Asian 2-pin PL lamps containing a capacitor, but lacking a glowbottle inside.

Okay, so the uploader of this video actually told me about the Ott-lite desk lamp that he has. Despite being electronic ballasted, it seemed to
operate the PL-S lamp with a starter, successfully, without any noticeable detrimental issues. Am I missing something?...
... unless maybe this desk lamp contains both an electronic ballast and magnetic ballast, which I highly doubt.
Anyways, here's the video: https://www.youtube.com/watch?v=eGQThMYJW14.

... has anyone ever heard of "Boneless" or "Cloud" couches? These couches have no springs or wood frames, at all, and show up to your door compressed in bags/wraps of some sort, in a box. I've got two of them that I bought for the loft:

Got a lamp that reached an EOL today? Post about it here.
Unfortunately I've got a lamp that reached EOL unexpectedly... one of my better CFL's... a 15w GE BIAX CFL, went EOL today. A component within the base
failed, so it did not light up when I flipped the switch on. Showed no signs of EOL earlier in the day and worked perfectly fine. I'm assuming it might've
been the starting capacitor that failed but I'm not sure. This was a Programmed Start CFL... the tube portion did NOT fail, so there was no EOL show, and
fair weather end blackening from years of usage. I've used that GE BIAX CFL in my kitchen since 2020. This is unfortunately the second 15w BIAX to fail
unexpectedly. The first one failed back in 2022. I took a pic of that one back then, shown here:

Well if/when you can, hold 1 if not 2 Westinghouse RMA 100 watt NEMAs for me. A family member of mine did a dump run a few years ago and threw away some of my fixtures which included one of those Westinghouse NEMAs. I don't mind saying I was quite ticked off at him afterwards because I got it pretty much the same way you're about to. I wouldn't mind paying for shipping if necessary.

@Ash, From what I have read in the 1992-1993 National Catalog, it was mentioning that the energy saver mercury vapor lamps were somehow rated for the same lumen output as the lamps they were intended to replace.

@Patrick - Correct. That Reddit thread sounds somewhat similar to what I’ve been experiencing. I really wasn’t sure if it was the magnetic ballast causing that, and after @sol mentioned getting it with incandescent lighting, I’m now almost certain that it is just a coincidence. I do wonder if it could be the fact that the lighting is now brighter after the magnetic ballast went in though, as the old electronic ballast was only a 0.75 ballast factor while the magnetic is 1.0 of course. Maybe the magnetic ballast pushed things bright enough to cause the flickering sensation. And as I’ve thought about it more, I think it may have occurred a couple of times with the electronic ballast, but it became pretty much every time I left the bathroom in the middle of the night after the magnetic ballast went in. I definitely think it is just eye strain though. These are two F40T12 lamps, so quite a substantial difference between light on and light off.

I do also get those colored patches you refer to as well. I usually get them if I look at a light and shut my eyes. The patch will be the shape of the light and sort of drift around a bit. I also see fainter patches in very very dark conditions (like under my bedcovers) or when I shut my eyes as well. As far as the flickering goes, I have never stayed up long enough for it to disappear (next time I get it, I’ll wait for a little while to see how long it takes) but it goes away immediately when I shut my eyes.

I have tried using nightlights before, but they are just too dim for me.
