Lighting

does anyone out there use 4000 kelvin metal halides??????

I used 4000k for years , soft corals do fine under them. They do look yellowish. You can use actenics to reduce the yellow. I only stop using 4000k this year,I went to a 6500k bulb. I ran 4000k bulbs for about 8 years or more. The reason I used them they were readily available and I did not notice the yellow that much; Until I started to check out other reef tank lighting.

4000K would be awefully yellow. I think the consensus is that 6500K is good, and 5500K is not as good.

4,000K, you find those at a antique store?

I don't think you are going to find many people using anything under 6,500K.
