Existing 12V : 50w Halo conversion to 12V : 7.5 LED lamps...

Not having done much in the way of conversions of this type, i'd be obliged if any you out there can confirm or otherwise, that standard 12V 60VA TX's are not suitable to drive low wattage LED lamps.

I've been asked by a new friend here, if his shop light fittings that consist of 4 X 50W halo lamps can have direct replacement of 7.5W LED lamps. I'm pretty sure that these low wattage LEDs don't like the standard wound TXs and require electronic units. ...So what say you?? lol!!

He has around 20 of these recessed fittings to convert. So it could be a substantial savings for him, as his current lighting load of these fittings are running at around 4 KWh!!

Apart from my initial query, if these LED lamps do require one of these electronic units, are they available to drive 4 X LED lamps? What sort of price would these voltage/current based units cost in the UK, just as a comparison, as i'm pretty sure they are going to be much much cheaper here.

The light out was much better than i expected and not that much different, slightly narrower beam though like you expect with LED and the client liked the colour but i did use the proper driver which did the 4 lamps. Its just a shame about the fins clashing on his fittings but may work better on yours.

Ah, .... but yours were 11W, ...perhaps that's what the LED replacement needs, 11W's of LED power... lol!!
