I'm gradually replacing halogen lights at home with LEDs.
We have a couple of 12V rails with a 5x35W rating when using halogens. When using the same transformer with LED's, can I use the theoretical maximum power? eg. If I'm using 5W LEDs instead of 35W halogens, can I mount up to 5 x 5x7 = 175 replacement LEDs? (If I could afford that of course).
Given that LEDs are not resistive loads, does this simple math apply? Or are there other factors that need to be taken into consideration?
At the moment, I'm leaving some halogens on each rail, as I've read that the transformer needs a minimum of resistive load (not sure what that minimum would be, nor I've found comprehensive guidance on this topic). The transformers are coil based (not electronic).
Any advice? Thanks.
