Yes, in the LDD-L, with a gimped voltage range. ;)

I guess it doesn't really matter a whole lot, though.

I'd recommend to use the lower Vero series and just use more of them, that way you could use LDD drivers (which top out at 1A) or O2Surplus' custom A6211 drivers that top out at 1.6A, but unless your...

Youre still going to need drivers that give a minimum of 77v. Lowering amperage only lowers voltage by a small amount.

Depending on which bin you got, the Vero would more than likely give you far better color. On top of that, what are the dimensions of the tank? Having a 150w spotlight isn't great unless you're...

I am not a fan of using dedicated red or deep red LEDs. They are much too distracting. You're better off using a good quality high-CRI warm white to get your red.

Many manufacturers use Cree as a description and not a brand name.

Why did they recommend the XR-E? Those LEDs are very, very old and inefficient. The XP-G2 and XT-E are the newer 'modern' Cree...

What light is it? If you mean the Marineland 'Reef Capable' garbage, then it's stupidly low intensity.

I would not have drilled holes in the heatsinks at all - it may not seem like it, but you've actually reduced your overall cooling, as now as air travels through the heatsink it will have less and...

If I run everything at 700mA, the LEDs use around 199 watts including LDD and HLG inefficiencies, bumped up to 1A that goes up to 273 watts. The heatsink with them at 700mA gets around 45C, at 1A...

There is no such thing as cooling overkill. I just wish there was something I could do with my Nanobox housing over my reef. The heatsink is 1.9"x34" and is like 1" tall, so it doesn't have a lot of...

If the heatsink is 70-80C, then the LED die will be much hotter, usually 10-20C depending on the LED C/W, PCB C/W, and heatsink C/W. An LED run at 40-50C, which is typical of a well-cooled array,...

Think of the heatsink like a sponge. You can keep putting more water (or heat) onto it and it will continue to hold it. If you wring it out (or add a fan), then all of that water (heat) leaves.

This is not correct - the heat put out into the room will be higher no matter what, as the heatsink is only holding onto it until the fan can blow it off, the heat load is always the same.
