Where can get a 20 watt round led driver with a 12v output ?

[Splitty]

Hi Forum people. First time post here.

I have a pair of semi flush fittings that are currently 10 Halogen capsules per fitting. I want to convert these to LED at 2 watts per capsule. Space is a very limiting factor. Each fitting currently has a round transformer inside. I only have an 80mm diameter space to fit one in but if I go for a round one as soon as I opt for 20 watts the only options I can find are drivers with an output voltage of 21 volts upwards ! The led's wont run off the original transformer, thought I'd give it a go but they go mental !

No problem finding a rectangular driver but they physically wont fit, I did consider fitting a pair in there stacked on top of each other but don't have the depth in each fitting for two.



The missus doesn't want me to bin em out for new ones either so I'm gonna have to try at least to get this sorted.



Any ideas folks ?

Could you make do with 230V led capsules as a direct replacement for the halogens? No driver needed...

WHAT !!! There is such a thing ?

I thought (stupid assumption here), that all LED G4 lamps were 12 volt only. Never occurred to me that there's a 240 volt option. Much to learn about LED lighting eh !
Thankyou for your reply. Nice 'n' easy solution. Cheers.

Not sure I'd want to run wiring designed for 12 volts at 230.

No, that would be incredibly dangerous!

The fitting has been designed and manufactured with a 12V transformer feeding 12V lamps. The internal wiring is unlikely to be rated for 240V and the lampholders definately will not be safe to use at 240V.

Please don't convert your 12V light fitting to 240V, this carries significant risks and could result in a fire or (potentially fatal) electric shock.

Hi. I hang my head in shame and hang up my tool bag. I must have had a brain fart or something...
My apologies for suggesting using 230V capsules in a fitting not designed for 230V.

Thankyou l had considered this too. How very dangerous this would become ! Back to square one, the search continues.

I expect that the drivers you have been looking at are constant CURRENT?
You need constant VOLTAGE.

I have seen 24v GU4 LED capsules
so you could use those with this round 24v LED driver

EDIT
AcTEC do a 12volt version that may fit, then you could use your existing 12v GU4 capsules...

Thanks for your reply, however, this is evidence of the problem I'm having. Its either 12 volts but the wattage isn't high enough or if I want to up the wattage to at least 20 watts, then for some reason the output voltage goes up to 24 volts !!!, or more.
Just can't seem to find a 20 watt 12 volt one that's round or small enough to fit my fitting. Cheers anyway. The hunt continues..........

Yes, thankyou, I stopped and thought about it afterwards, I won't be doing that ! Thankyou for your reply. Cheers

No worries this end, I got caught up in the moment, thinking, wow ! you've given me an easy solution. Then I stopped and thought about it (as you do) and I thought , Hmmm, hang on a minute. I know the thought was there, cheers.

Howz about this one:

https://uk.farnell.com/traco-power/tmw-24-112/power-supply-ac-dc-12v-2a/dp/3777602

A bit expensive but a quality item and would do the job, assuming depth of 24.5mm is not too tall!

Or here's a possible cheaper option, if you could separate the wiring into two groups of lights, you could fit two of these, each driving half the bulbs, but I'm a bit wary of the suitability of the current rating for continuous use, the actual o/p voltage tolerance, and possible safety implications:

Thankyou for these, It's time to have a chat with the missus methinks. Nearly 40 quid is more than the light fittings are worth. Even she wont go for that ! The cheaper option comes really close though but at 18 Watts, they're just not gonna do it. From what I can glean from the net the wattage should be marginally greater or equal to the demand.
