according to the description and what we're seeing that's not true dimming but your typical select-a-watt ballast where it has multiple power settings.

For true dimming the only one i know of that's readily available is the Sfiligoi ACLS system.

And regarding shimmer, my tiny Kessil a150 LED has more shimmer than my 250w halides had! Fixtures using many separate 3w chips don't produce the same shimmer as the cannon style pendant though.

I don't think you can beat MH, Imagine 2 400 watt MH over a 200 GL, wow but I just can't do it why, Costs, Heat, Glare, I have 2 Maxspect Razors over my 150 and They don't make a difference to the Fish that's for sure. The Corals seem to be happy, nice and bright, But what I enjoy is the Lack of heat, Lower energy cost, No difference in spectrum for awhile and they were affordable.

I hear people say you can have SPS with LED, that's a crock sure you can, They are bright.

Should that say "can't"?

Do people really still say this?! People have been growing SPS under LEDs for years now. Some people really need to get out from under their rocks
