You have to take into account that LEDs have a threshold and that below that threshold they will NOT light. So IMO it would be better to put a resistor in parrallel that is able to draw the full needed current. When the light actually lights a slightly higher current is drawn, but I believe this will be within the abilities of the other hardware, as incandescents also have a bit of "play" to account for manuafacturing differences... But the most simple solution is to just keep THAT (or those) light with a bulb, replacing the HVAC-lights IS worth the effort (and cash). JAN van de Wouw Thinking Different... Using a Mac...
