OHHHH you're lighting your planted tank! In the PM you had sent I thought you were doing a reef lol, that's why I sent you to my big reef lighting thread.
Cool white LEDs are blue LEDs with a little bit of phosphor applied to them, and remain mostly blue spectrum. Plants want way more red than blue for photosynthesis. I've had the best results recommending a 1:1 ratio of warm white and cool white LEDs.
The Bridgelux chips (the BXRA3 series, the Vero series) have the best color of any listed, and have excellent efficiency, as well. The Luxeon M is not readily available in warmer whites, so I would scratch that off the list.
If you want more even PAR across the tank, then I would use '3w' class chips. If you want a more metal halide approach with more intense shimmer and higher intensities in certain places, then I would use the Bridgelux BXRA3 or Vero in clustered pairs. Both put out enormous amounts of light without a lot of current (they are multichips, so their forward voltage is higher, but higher voltage lower current drivers like the LDD are dirt cheap). Hoppy's PAR calculator doesn't really work all that well with them, so it is difficult to calculate what your PAR will be, but if you keep to using the same amount of lumens that the calc tells you to use, then you'll be in the ball park. There are no wider reflectors at this point for the Vero 10, so the BXRA3 may be your choice, along with the Ledil Brooke W reflector (which is 50 degrees). You can run two BXRA-3 in series per LDD. In the past, I ran two parallel strings of two from a single LDD-1000H over my reef tank, and let me tell ya, it was some intense light.
Also, I'd recommend to use a Meanwell HLG power supply to power the LDD and not the LEDgroupbuy power supplies. They're more efficient and much higher quality. Wattage depends on the final calculated wattage of the LEDs you want to use, add up the watts and then add 20%, then pick the HLG-xxxH-48 or 48A that corresponds closest with that wattage.
Hoppy's calculator suggests ~32x LEDs at 700mA 220lm each, using 60 degree lenses and the lights 8" above the top of the tank. That's about 7000 lumens total. Using the BXRA3, you'd want to use 4x BXRA-30G800-B-00
and 4x BXRA-56C1100-B-00
at 500mA each. That will give you around 9,000 lumens or so at full power, so you'll have wiggle room. These
are the reflectors you want. You'd need four LDD-500H, and an HLG-100H-48A
to power them.
