Rated 3 out of 5 by Theriaultb Solis Tek ballast / No Go
This bulb does not work in the solis tek stk600 ballast. The stk has a fault protection that senses something isn't right and shuts the bulb down. The ballast has a toggle switch setting for 400w and 600w in both mh/hps.
Bulb looks well built and doesn't have have a green tint in the glass which would normally block out the uva/uvb spectrums. If it worked in my ballast I would have given a better review. May want to call up your ballast manufacturer before buying bulbs to make sure they can run before investing your money on something that will sit around and gather dust.
