I have a bunch of 10W lamps (like this one) with incorrect power adapters for the emitters - the drivers are meant for a 1x9 configuration (35V, ~300mA), LEDS are 3x3 (~11V, ~900mA).
I am fine with running them at 1/3 power, for now.
Question: what happens to the remaining 2/3 (~23V, 300mA)? Is it radiated off in the driver (and is that a concern, like a short circuit might)? Or does the driver deal with that differently?
