MR16 LED's

[Hawk]

Hi,

I was in the wholesalers last week and was getting MR16's to use as a demo for a client. I was going to get the driver to go with them, however the sales rep said that you can directly replace the current halogens with the LED's.

I did as he said and they seem to work fine. I thought that all LED's needed a constant DC supply. Is this not so?

the led spots (gu10) have the driver in the lamp

Thats why there more expensive

Yeah but for the mr16's I would have thought that you would need to take the ac transformer out ant replace it with a dc driver. Ideally I would take the mr16's out and use GU10's, but it is a large premises with time constraints.

Some elv halogen transformers work with led lamps. Some don't. I just replace with 240v led in the case of downlights to avoid any titting about anyway.

Yes some work some dont...


Its generally the older transformers that aren't compatible...

Some old transformer will work for a while but will burn out quick

I have been using OLD wire wound Thorn EMI TQPS 225 transformers ( over 15 years Old ) to power my MR 16 LED`s for the past 6 years I have NEVER had any problems with wire wound tranny`s or LED`s & I can now run more lamps per tranny. It`s only the electronic controllers that I have had that failed !
On the point of GU10 (230v) versus MR 16 (12v) I find that the MR 16 (12v) last longer (in fact the only one`s that I have ever had fail, were because the electronic tranny failed, don`t know why, but the 240v GU10`s I have had many fail, presumably more electronic components to go wrong,
