Re: MH Lighting/Ice Cap ballast
Tom Barr asked:
"Has anyone purchased the new electronic Metal Halide Ice Cap ballast on
the APD ? ::snip:: "
I bought an IceCap with a 175 watt 10,000K bulb because the higher kelvin
bulb suposedly had a higher PAR rating. The plants didn't like the blue
light so I switched to a 5500K bulb. It was WAY too yellow after seeing the
blue/white light of the previous bulb, so I switched again to a 6500K
Coralife. This is a happy medium in terms of color rendition and plant
growth. Throughout all three bulbs, the IceCap produced an annoying flicker
at odd times of the day. I downgraded to a coil/capacitor ballast and am
very happy with the end results of all that experimentation. If I ever do
another tank, I'd go with an 6500K Iwasaki 250 watt standard ballast.
