Careful application of heat, either with a heat gun or a torch can help. A stronger penetrating oil such as PB Blaster, applied in conjunction with heat will also help.

I know heat can help, but be careful with that...

Presumably wasn't selling well and was costly to make. As LED technology advanced and they made newer designs, there was no reason to continue the selenium.

Thats just my guess though.

On my QL 114, three of the four screws holding the ballast door in place are completely seized up. The one I was able to get loose with some effort, but the others are completely stuck. Even after applying WD-40, they still won't budge. How do I go about loosening them?

Why don't they do the Selenium any more?

I wonder if there's a version for B22 lamps, maybe 2 hook-shaped wires to hold the pins on the side and 2 screws for the contacts?


The E27 wire one would be safer if they put the top half of a plastic bottle on it

I have done something similar here, you gotta do what you gotta do!

I think that is quite innovative 😃, and in places like some parts of India, where you probably can’t just go out and buy a lamp holder it’s probably the next best thing!
Yeah it’s dangerous, but they probably don’t have a wiring code or a BS 7671 like western countries have?
Not a fan of the screws as the wood could get damp?, but the wire thing is quite genius thinking 🤔

But the thing is no one is that desperate for an E27 holder, proper holders aren't that expensive. A plastic one is about half a dollar and a ceramic one is two dollars

It's not about the wattage, but the voltage, which is probably 230. Wrong side of your hand and your electrocuted

Though the idea wasn't quite a bad idea, though it is dangerous with bare metal.
