250 watt 20000K DE users

DarG · 05/11/2007, 02:12 PM

Looking for input from anyone who is using 250 watt 20000K DE Metal Halide.

Are you happy with your lighting, color, growth / health of corals? What corals are you keeping? What supplemental lighting are you using?

Thanks for any input.

What manufacture are you asking about?

i used a 20k de bulb and didnt like the color output, it was WAYYY too blue...it almost looked like the current 65w dual actinic pc bulb, color-wise. i replaced with 14k bulbs and the color output is perfect now.

Just a general question, not any particular bulb manufacturer. The information I'm looking for is generally related to par and I need some input from users of 250 watt 20000K double ended bulb users to satisfy a curiosity. So, do you use them?
