Hi everyone,
noticed a thing here, I cant understand...
I have this quad light here at the final (mechanical) stages:
before final installation with driver and sense resistor, I have my lights run on different levels for some time, just if that might make some differences to non used emitters.
The setup is as shown (wired) + a 4-cell Li-Ion pack + a large 5W poti.
When set to any drive current, this one increases (sometines considerably) when the assembly gets warmer.
:thinking:
Should the emitters not get less efficient when warm?
