Hi guys,

Quick question regarding 5x MR16 (Gu5.3) Led bulbs in downlighters. The customer used to use halogen but has moved over to LED. They had stopped working due to a faulty 12v transformer
I've just replaced the transformer with a constant voltage driver (1-25w) but with any more than 3 bulbs inserted then they all seem to flash. Due to time I left it working with 3 and was due to return to sort it but she says her son has replaced the driver with a 12v transformer and they are all working fine!

MR16s don't have built in drivers do they?

Cheers in advance
