Hi I'm working on this project and the shop send me the wrong voltage LED driver that I've asked for, but I'm just wondering if it would in fact just work. Here are the details:
LED Driver Specs:
Output 30-36V 1200mA 40W
LED Specs (planned to put two in parallel):
20-25V 600mA 20W
The wattage and amps add up, only the voltage don't.
If this would burn my LEDs, I'm thinking of adding another two small loads in series to each of the two LEDs that takes up around 3-3.6V and 3W. This should sum up to 28.6v total which might be close enough to not to burn things out but eats up 3W from the LEDs which technically makes them not operate at maximum power.
What do you think?
Btw, does anyone have a way of how to calculate/estimate how big of a heat sink I need for these super bright LEDs? I have some small CPU fans that can also be used to cool down my LED shell which itself is designed to dissipate heat.
Thanks and appreciate for any help!
