HQI vs. Regular Metal Halide

[RayAllen]

I ran a Mini PFO HQI Pendant with a 12k reeflux. With a IceCap ballast. NICE! I miss it, lol

i run a reeflux de, on a coralvue ballast(electronic), bulb is 6-7 months old and i havent noticed any issues, you can check out my setup to see how small the ballast and pendents are

i ran the same for more then 12 months at a time with no problems

The DE lamps where coral vue 14K 250w(before Reeflux) and coral vue electronic ballast(which I still use, but with SE Reeflux lamps. I use a light meter that measures foot candles, when the lamps where new I read 3800 ftc at the water level and when my SPS crashed I read 1500 ftc. And you could not tell the difference by looking at it, there was not a color change in either lamp, nor could you tell the lamps had lost so much.

How long did that reduction take? About 6-7 months?

I've always thought DE had more "pop" in their color and better depth penetration than SE. But, again that's just a personal preference.

Coral growth wise, I haven't seen a big difference in using 250w SE and 250w DE.

Justin if you are talking about my experience 8 months. When my SPS crashed I checked everything and when everything checked out OK I checked lighting and found thoses results. And I know a light meter is not a par meter but over 50% drop in lighting output I would think would be proportional to 50% drop in PAR output. Since DE is smaller than SE you would naturally have a more dense light in a smaller area, kind of like a flood light versus spot light effect(probably not a very comparison but hopefully you get the idea)
