I got 2 origanlly with a beamswork light. Noticed they slid into the fan slots on a makersled heatsink on a past diy build orderdoand extra so I'd have two for this build from "topdogseller" on eBay@Kampo where did you get those fans?

So, I'm looking at this board. The blues draw 1.5 peak amps. The Mean Well LDD puts out at most 1.5 amps. Is there enough power two drive two of these in series off a Mean Well LDD? I get that full power would probably burn out any corals but is 750ma enough?
Whoops! Basic physics fail. ;EggonfaceIf wired in series you as voltage not divide amps. So for 2 in series you would need 5 Ldd.
395 - 600
450- 1400
420- 600 (says 1amp but don't think there are any Chinese 420s that take more than 600
480 1000
White 600
That's how I wired mine
my friend did just like this with 24v 5a power supply and its working without any problem. Yes better with cureent limiter, but you can run without 2,3 year with good cooling.Sorry to inform you but you can't use that controller (well you can but not how you are suggesting) to power constant current LEDs.
Constant current LEDs need a driver to moderate voltage. Even being 1 volt off specs can mean giving a led thats raited for 600mah 2+ Amps they will be very bright for a short time.
I will use 24v 5a power supply

@Kampo, it just occurred to me, looking at these (I'm not super experienced with LEDs though I get the concept). These will require a CV driver, right? The drivers I was about to order were LDD CC drivers but these LEDs take a fixed voltage... or am I misreading/understanding something?If wired in series you as voltage not divide amps. So for 2 in series you would need 5 Ldd.

Constant current. But you can look up the specs to know roughly what voltage they will be at a certain current.
constant current driver basically just ramps up voltage to a led chain until it's running at it's set current.
I see a lot of talk about drivers and arrays but does anyone have any advice for power supplies? I ended up settling on the 5 channel custom cree arrays. I bought 4 but will probably need 6-8 for a 480 gal tank with each one able to draw 5 amps. I'm having trouble figuring out what power supply would be able to meet my longterm needs

What do you think about 60° or 90° Honeycomb Lens form topledlight?
Or does the Wide Angle TIR Lense Kit fit the round 120mm or square 100mm PCB?
It might be better to build a Diffuser like the name Brands do it... or?
P-CC looses only 20% with Diffuser but the light spreading is much better... T5 like or?
All so i would like to be able to drive @ max & dim them down...
The XP-G3 (2-3°C/W) with 2A there is no LDD Driver they sound nice with Overpowering
I found a power test @ German Forum they took 16,6 A & 5,42 V ~90Watt for 10Sek! ;Spiderman "Sweet Spot 6 A (1622 lm @ 3,76 V / 1440 lm @ 85 °C Tsp)" ;Stig

I all so think about ordering an empty Chinese 5 channel PCB, soldering paste & the 3535 SMD´s i want... soldering with a hot plate doesn't look so hard (never done it)...
Or the Type 3 (& maybe change some later)

I would like to know if these boards provide that glow like in the photo.
