Wish i had a 400 watt HQI ballast

I would like try but don't want to be disappointed if it is dim i have a Hamilton fixture with a 20,000k bulb and dont like it at all looks washed out Maybe ill try the XM 15000k or 20,000 not what would look better

For technical data on many of MH bulbs, you can find them at Sanjay's database:

For more technical data and some color comparisons, you can check out this site:

BTW, with a little bit of color spectrum knowledge, you can pretty much figure out what a bulb will look like with your ballast using Sanjay's site (by reading spectrum plot).
I am using a pair of XM 10KK and found them a little bit yellow so I supplement them with some blue T5 bulbs.
