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.
