12V V 24V

Post by beebee »

Will a 24V light work when connected to 12V? Will it work at all or just be half strength?

It'll work, it just won't be bright. What are you trying to do?

It will work but instead of being, say 100w it will be only 50w.

I bought a sealed worklight from Queensland Diesel Spares (a truck acc. store for the southerners) and connected it straight to the battery and nothing happened. There is no indication of what voltage or wattage it is either so I thought that maybe it was 24V and this prevented it form working. Maybe it needs a relay :?:

It doesn't sound like there's anything rattling around inside and as I said it's sealed with a rubber outer too :!: Might have to have another play :D

COULD IT HAVE SOME SORT OF INTERNAL ELECTRODE THAT REQUIRES 24v TO FIRE IT UP :?:
Joe.


To succeed, focus on the solution, not the problem.

Actually it'll be a lot less, a Halogen lamp can loose 30% of it's output by only losing 10% voltage.

I didn't realise that this thread was still kicking :cool:

I went back to the place where I bought the lamp from and aparently it isn't a sealed light :oops: so they sold me a bulb for it. I asked about fitting it and they said that you just pull off the rubber surround. I have since tried a couple of times but decided that it wasn't going to happen and it is still sitting on the shed floor :D

So yeah, the problem is the user :oops:

Thanks for the replies
