I'm on a high just absorbing all of this information lately, thanks a ton to everyone that's helped so far!

Based on my current light budget, here's what I'd like to put together:

5 x Samsung FB22B https://www.digikey.com/product-detail/ ... ND/6624010

1 x HLG-320H-48 running parallel https://www.digikey.com/products/en?mpart=HLG-320H-48A

Some questions I still have that I'm hoping you can help with:

1. Is this a proper driver to run these at 75%?
2. What would the total watt off the wall end up being?
3. How much space could I cover with this?
4. Heatsink - I know I can probably get away with just aluminum channels here, but I am in a pretty hot area so I'd like to stay as efficient as possible. HeatsinkUSA is out of stock of the 1" wide heatsinks.. would I be OK attaching them to the 2" wide instead? http://www.heatsinkusa.com/2-079/

Actually I figured out the different model numbers (Samsung doesn't make it easy on us!) and looks like using the calculator here http://ledgardener.com/parallel-strip-build-tool/ I would be pushing it with the HLG-320 and better off with the HLG-480?

I was waiting for one of the strip guru's to chime in but...
1) I would go 480.. then you can go 100% if you want and with question #4 they can handle full power.

2) easiest way is get one of those meters you plug in the outlet.. another is hook up a multi meter testing at different settings on your dimmer.. use V x MA=W. the AC side will be slightly different because of driver efficiency.

3) I would assume 4x3? maybe 4x4... that's more for a strip guru.

4) of course!!! who wouldn't want a extra inch! ( sorry it was set up to well) bigger normally is better in most cases. ( coming from a giant lol)

A 480 would allow you to push the limits of the strips but a 320 would be safer. The 480 is more than powerful enough to overload those strips. I’d go 320.

If you know what your power is on the DC side, you can use this along with your driver’s efficiency to figure out wall draw. For example, if your strips are getting 300W and your driver is 94% efficient at this power, you can go 300 * 1.06 and determine that wall draw will be 318W. 318W/120V will be a draw if approximately 2.65A on the AC circuit.

If we look at this in terms of quantum boards, this would be 72 diodes per strip * 5 strips = 360 diodes - just over the number of diodes on a single board. That’d mean you could do about 2x2 to 2.5x2.5 or so.

As JGG said, bigger is better for heat sinks.
