Hi yall, I'm looking for a fixture that runs 4 F40T12s, preferably a wrap around, but it can be other styles too! In this case the cheapest option is the best-

I've discovered that blue and high kelvin indium iodide lamps often have only 6000 hours rated life.
Why?

I think these getting dimmer because the tube is even more hot than in exposed tube CFLs as the phosphors degrades faster.

A bit off-topic, but I wonder how your *parents* divorcing shall force you to abandon *your own* collection? You defintely look grown up enough to be able to claim your own rights, sure?

It's more a space issue. I've accumulated more than I'll ever need, especially in the consumer lamps department. I have enough lamps for usually any project that friends, family, etc ask for, especially when they want to source incandescents, CFLs, or older LEDs for a project. I can't feasibly take it all with me. Currently, all of my stuff is stored in the basement or shed. The basement is a decently-small percentage, but I've taken over a large chunk of the shed.

You see, I do not want to pay for storage costs. Being that my parents are essentially downsizing, it'll leave far less room for actual collecting space, especially when compared to what we have now.

@Multisubject – I can drive to you, no problem.

@Baked bagel 11 – I can definitely try and arrange something for you.

I am very sorry to hear that, but I do agree with @RRK that you have rights to your own collection...

Anyway I don't have access to a car right now, so unless you want to drive all the way to me I don't know if that is really gonna work.

The PCB is correct. And in the last time my computer technician disassembled the UPS, all components on the PCB looked intact.

What I’m noticing is that the bare spiral bulbs rarely go mercury starved but I’ve seem them on some occasions back when CFLs were popular, but I’ve noticed that the covered CFLs, such as the A19 and globe variants, tend to get dimmer and dimmer with age, they tend to start dimmer and lose their ability to reach brightness when the bulbs age.

Covered CFLs start dim when new but as they age they start dimmer and also lose their fully brightness. I’ve seen more covered CFLs glow the dull pink hue than bare spirals.

This tells me nothing...
Question is, whether there isn't any fault in it, e.g. a relay on its way out, broken PCB,...

Hi Maxim,

I'm very sorry to hear that, and would happily take some stuff off your hands, though the 10,000 mile distance is a bit of a pain!

I know what you're going through, it my parents split up just over a decade ago, though I was too young to properly understand!

Best of luck with all of this.
