I’m considering buying a Cree CMA3090 to play with . I was originally going to get one of those mystery “100w” leds on amazon / ebay that seem to be popular on youtube, but they usually had a low cri or it was not displayed. Or they just suck sometimes?
Was thinking one of one of these drivers to power it off a 12v agm battery. Do yall think these drivers are a good choice?
THIS or THIS
I should be able to set the current of the driver by measuring voltage across a really beefy shunt resistor right? (than calculate current)
I guess people usually use a low oem resistor as to not interfere with things they measure, but for my application wouldn’t I use a higher ohm resistor to not damage the driver when testing?
