5Amp Constant Current LED Driver
If anyone has any LED projects without on-board regulators, here's a cute 5A Constant Current/ Constant Voltage board I'm using for mine. So far I don't hear any RFI out of it, but will look on the an...

One thing never mentioned here is that the current draw from an LED WILL change upward as it warms up, and it can roll right through the max current for the device if you are running it hard. I have that problem with LEDZILLA, and resistors wont fix that either, so the second board I bought will replace the V only regulator on it.
i will say i see the exact opposite with a led array

i have this hooked to a lab dc CV,CC PSU, after about 1 minute it starts dropping current requirements, roughly 1ma a minute, that said it is regulated as it doesn't drop regulation till about 10.5v
