Suggestions on LED bild Part 2

[tangstank]

I'm downsizing to 180 gallon. For the new setup I want to have just a few LED's (currently have have 60 (3 watt) x 3 panels) & I want to go with 4 (50 watt) x 3 Panels

On each panel I'm thinking of
50 Watt Royal Blue x 2
50 Watt 6700K White x 1
50 Watt 10000K white x 1

I want to go with CREE XTE 50 Watt LED's. Each LED has a specification for 33-36V 1.5 Amps & I need to have the capability to dim using my Apex.

I'm expecting the panel to cover 2' X 2' area to a depth of 2'.
What do you think of this approach?

I have 6 x Meanwell 60-48d drivers. If I use 1 driver for 2 LED's in series, I would be powering them with 24v each 1.3 Amps. Is this doable?

Please suggest

I think it's an ok approach. Honestly I would consider adding in a few more colors. I'd strongly consider adding in some 420nm violets, 470nm Blues, Phillips rebel es Lime diodes, and a handful of warm whites. What you have would be fine but I think broadening your spectrum some will improve the visual appeal. The 420nm will help tremendously with growth, and the Lime and warm white will help with color rendering quite a bit.

Nope.. your numbers/terms are switched
In series they won't work as you would need a driver with an output greater than 72V to overcome the combined forward voltage.. which the ELN is not capable of doing.

In parallel (yuck) it would be 650mA per LED which is underpowering them.
Not to mention LEDs do NOT parallel properly as they tend to not share current equally so its generally avoided except for those that don't have the money to do it right.

For those LEDs you need 1 LED = 1 driver

and "tight" clusters of LEDs = great color mixing but = potential spotlighting and thus you need to raise the light higher to spread out the light.
