Custom RGB+W COB LED fixture driver

[Saucy]

I have a RGB+W COB LED that I want to turn into a custom aquarium light for my aquascape.

I'm wondering what Driver I need to buy if I want to be able to independently dim any given LED group on this COB (Red, Green, Blue, White) to customize the end result coloring for the light. Do I have to buy 4 dimmable drivers (one for each color) in order for this to work or are there drivers out there that have multiple channels for dimming? This project would be powered by Mains voltage. Should I be looking at Constant Current Drivers for this application?

I also don't have an issue underdriving the LEDs to cut down on heat and extend lifespan. I don't necessarily need the full 100W capability advertised if that helps my situation at all. I assume the 800mA used in the tables below is for the max rated output of the COB?

any input is appreciated, thanks!

RGB+W COB LED 4040 100watt
Color	Voltage	Current	Lumen	Wd/CCT	Series/Parallel
Red	22-26V	800mA	800-1200LM	620-630nm	10S1P
Blue	27-30V	800mA	400-600LM	460-470nm	9S1P
Green	27-30V	800mA	1400-1600LM	520-530nm	9S1P
White	27-30V	800mA	1300-1500LM	3000K~6000K	9S1P

Infinitely variable colour might seem attractive but only using the basic RGB and switching them on/off can often give the colour you need. Sure you want 'full' control? If so then, yes, get individual dimmers (simple PWM).

Heatsinking WILL be required. I have an aquarium light and it MUST be submerged to prevent overheating and it's not even 100W!

Thanks for the input, I do plan on heavily Heatsinking this.

So I found a Driver that appears to be mostly perfect for this application with exception that the input voltage is for European mains (220VAC) instead of North American (120VAC). Could I just use a 220v to 110v adapter to power this?

4 Channels Constant Current 75W Dimmable RGB/RGBW LED Driver with RF SRP-1009-75CCF

The SRP-1009-75CCF is a ENEC approved 75W constant current RF LED dimmable driver with 200-240VAC input and 4 channels PWM output. The output current is settable from 250mA to 1500mA by DIP switch on the driver.

Using a 110 V to 220 V converter is a clumsy way. 110 V controllers (Tx + Rx) are readily available, e.g. this one.
Also it seems that you'd have to buy the remote control transmitter separately.
