The cree LEDs are US made and they are all tested and sorted into batches so you know exactly what you are getting, I think that is one of the main reasons people like cree.

I would think that if all the LEDs are the same model from the same batch that the differences in them would be try minor, none significant.

My understanding that running in parallel voltage stayed constant and that amps were distributive. the 3050 are by far the best choice after researching on the cree site and playing with there programs that calculate output and efficiency. The 3050s are up at 150-160 lumens/watt in the 1 - 1.4...

One thing I have been wondering, but have yet to find a definitive answer about is, do you actually need pucks when running from a high power power supply. For example, let's say I have a cv/cc power supply, and it outputs 48v and 5 Amps. The cree cxa3050 runs in a range from 1-2.4 amps, would...

This is the initial build that I found: https://www.circuitsathome.com/diy-2/high-power-led-grow-light-a-build-log Then I ended up here, same concept though, using CPU heat sinks. The biggest thing I have yet to fully flesh out is how to handle splitting up the power to run it to the pucks...

I think the ANP151-110P-277 would be pretty ideal, but I have yet to take my DC electronics classes :). It looks like it is a very new product I am not seeing any pricing information, I am not sure if it is purchasable yet. I think the big obsticle is likely cost, you would need one...

I think there are many people including my self that signed up on this forum specifically because they are interested in cree LED grows, my self included. I have been researching many different build possibilities with the cree LEDs. The problem I have run into in relationship to the 3590s is...
