165 watt LED

How high above a 29 gallon nano cube should I mount these lights? What is the intensity that I start at and how often should I increase?

total wattage doesn't tell us anything, what is the wattage of the individual LED? You can have a 165 1 watt led's and they would only be good for a couple of inches penetration.

8-10 inches should work, start them pretty low 10-20% and go up noore than 5% a week until you reach your desired level.

I keep seeing this statement and I have no idea where this myth came from. As an electronics technologist with a major in microwave communications I will tell you one thing:
It had NOTHING to do with individual led wattage and everything to do with TOTAL wattage. Total wattage and efficiency of the LEDs. We are not shooting light bullets at the tank where size matters, but blanketing the tank in waves of light where the total matters.

That being said, most smaller LEDs do have lower efficiencys in the 30-40 lum per watt. Some manufacturers brag about 70 lum per watt. Bridgelux exceeds that and Cree are exceeding 130-140 lum per watt.
But there are some small wattage LEDs in the 70-100 lum per watt that are just 0.2 watts. But 10 of those are JUST as good as a 3 watt LED under driven to just 2 watts if it's efficiency is also 70-100 lum per watt.

So let's stop spreading the myth and concentrate of led quality.

Bridgelux are very good
Cree are the best

At least for now.
