MR16 Lamps
 

I have a fitting with 4 MR16 lamps and I would like ot consider changing to
LEDs.
In the base is a round transformer. Am I right in thinking that I need a
certain minimum load on this and I may have to retain at least one halogen
lamp to do this.
Alternatively should I remove the transformer and fit an LED Driver.

Any suggestions? It is the type where the lampholder can be slid along
conductive bars.

If its a transformer there should be no need for a minimum load.
The lamp needs to work with 12V AC with a reasonably large tolerance,
which they all do AFAICS.

Its SMPSUs that need a minimum load.
LED drivers are just a SMPSU that is designed to work at very low loads
and still give a constant voltage..

It might save you a tiny amount of electricity if you do.

Make sure there is plenty of ventilation, if the base gets hot the LEDs
will fail early.
