After very vise advices here I decided to switch to Bridgelux BXRE-65S1001-C-74
BXRE-50S1001-C-74 . 6500/5000 k 2:1 ratio, how many units I will be need total for my 120 cm tank
And what driver and power supply will be suitable , I heard good thing of mean well products
First thing, though your choices are just fine, going only as low as 5000k doesn't give a realistic sunset/sunrise IF that matters.
Lower k good whites also have a better red component. There is a risk of personally not using them as much (lower current)
as you would diodes at 5000K.
Next drivers will depend on if you plan on controlling them and what control..
Third if you use 1w/gallon 300L =80gal 80W evenly spread out over tank.
Shouldn't be a problem since 2 rows would be better than one strip..
Soo 6 of each, 2 rows of 3 pairs.
More than enough light.roughly 12x 17W = 204W.
dimming will be important.
Good thing is a single channel (either 6500k or whatever) is enough power..
In other words overkill but good for uniformity.
NOTE: WATTS is not a good predictor of output but it is use-able if one is aware of issues.
Most common system of drivers is LDD-h's (or possibly LDD-L's but w/ a caution), 5V PWM based controller and in your case 48V power supply w/ sufficient wattage.
Instead of strings picture one COB. BTW more than one Meanwell LDD driver on one channel in this system.
SOOO decide on controller.
You ca nadd circuitry to change a 5V PWM to say 10V analog (0-10v dimming) but just adds cost and a bit of complexity.
