One reason why the 5w halogen may not work in the track light is some tracks that are low voltage use somewhat of a hybrid transformer/switching supply and have a minimum draw and will not operate unless that minimum is fulfilled but that all depends on the supply
yeah, I suspect the same thing too. but then I went barebone and connect the 50w halogen straight to the circuit and Arduino, didn't work. I don't think I fed enough current to make it 50w. Pretty sure I have 12V though.
So, say, will it work if I use 16V or 24V power supply?
