Ok its about time for me to change my bulbs on my MH setup (~2 yrs old). My ballasts are IceCap 250-I. I know they are specifically tuned for Iwaski bulbs, but they only come in 6500 K and I was just curious what would happen if I put a higher K bulb in which of course would not be Iwaski. Come on I know people have tried this before . Thanks.
