The wavelength is 256 nm from an unshielded "fluorescent" lamp with a quartz tube. It's definitely different than a so-called black light. There are no cheap answers, not only is the lamp special but...

From their site:



Less than 10W power, or about the power requirements of a single modern LED (Cree XML).

I only need four channels, but I need it replicated at least three times to drive three planned "clusters" of lights over my 200 gallon.

And I'm not good at programming Arduino. Unless you can...

I'm interested, but would be using a lot more than 4 LDD's - probably somewhere around 12. Would this work with your setup?

The price tag is pretty competitive.

If you can believe the manufacturer's statements, a 200 W induction light is close to equivalent to a 400 W MH. Figure a five year operating lifetime, you're...

You can always go lower in current. 600 mA would be fine, and would extend the lifetime of your LED's.

Going higher with a resistor in series with your LED's will still drive everything to the...

Giving in to my water - Planted tank with Africans?

I think that 80 XML's will be overkill. You'll be at 400 - 500 PAR. There are some spreadsheets here for figuring out how many LED's and how much light, Hoppy's set one up.
