M Monkey19939 New Member Jul 16, 2007 #1 I need to drive an MR-16 LED lamp using a 12/24V Incandescent Light Bulb Dimmer. Problem: that dimmer is expecting some very low resistance loads and MR-16 LED Lamps are designed with IC LED drivers (very high resistance). If I connect a 10-ohm 10-Watt Resistor in parallel with this MR-16 LED Lamp then it works. But wasting lots o energy on that Resistor. Solution: a trick circuit (low resistance and low current) to turn ON Dimmer so MR-16 LED Lamp can function normally. Thank you for helping out Attachments Dimmer.pdf Dimmer.pdf 127.6 KB · Views: 3,800

Hero999 Banned Jul 17, 2007 #2 Is this an AC or DC circuit? Perhaps it might be easier to build your own dimmer from scratch.
