K2 Viper 150w Bulbs

[swivel]

hey i was wondering if i can use any brand of bulbs for this fixture? I am new to metal halide. I was wondering what brand would be good for colors and growth? I'm using this for my 20g cube frag tank.

i believe any DE bulb will fire in that lamp. i've used too many to list in my older viper.
