I'm really surprised that E27 lightbulb sockets are considered fine for multi-kV voltages (there are sodium vapor bulbs without an internal igniter that have that base and require upward from 1.5kV to ignite).
@robryk Hey I've got a spotlight that needs that but don't have one. Is there any way to make my own bulb inside electrical things like this, table lamps etc?
@freeschool I'm sorry, I can't understand the question. What does your spotlight need? What do you mean by making your own bulb?
@robryk Is it possible to make homemade bulb?
@freeschool What kind of bulb? Incadescent (with a glowing filament) or some other?
@robryk I guess anything fitting E27 or even being able to take a bulb holder and modding it to have something more homemade...
The question of "why" is important here.
One could make a LED bulb by buying a E27 "plug", an LED, making a PCB with the power supply for the LED, putting that together and attaching a cover of some sort. It will be one to two orders of magnitude harder to make than an LED bulb made serially.
I don't know much about processes needed to make a filament bulb (at the very least that requires working with glass, but I don't even know in which order such bulbs get assembled).
So, if you just want a working bulb, I'd probably buy one. That need not be the case if you want to figure out how to make a bulb and are fine with having to make a few of them before they are good enough (because you'll learn about random important things along the way).
(Oh, and don't even try to make fluorescent bulbs. They are nasty in all ways I can think of -- require nasty gases inside, high voltage, can produce UV incl. UVC that needs to be filtered out lest they damage eyes of anyone nearby pretty quickly, ...).
@robryk Good question - at first purely to not buy things and make it / see how possible it is...
sort of have the electricity so how hard is it to pass through a lamp unit ! :)
Good to rule some things out... hmm thought smoe more more-'analogue' style might be possible with some selotape and metal lol 9creative way physically)
I guess I should search youtube but good to ask as well - any more thoughts more than LED as safest basically?
@freeschool And easiest (as in, I would roughly know how to make a LED bulb, but I can point out many things I would have little clue about if I wanted to make a incadescent lamp).
