does it have a ballast?

if its blue colored its m/h if its orange glow its hps

It didn't come with a bulb man^^

It should say it on the ballast OP

ahhh ok then yeah it should tell you on the ballast.

get a bulb and try it if u got a ballast
it wont blow up

its a MH lamp i found it on the net. is it worth useing for budding? i have a 400hps but its tide up right now can i use the mh for budding then switch over tho hps when its done being used at the other place? or should i stay with the cfls till im ready for the other light. never used a mh before that why im asking.

MH is fine to use in flower, some growers prefer metal halide instead of hps. Some say it gives you a better quality bud

m/h buds, and cfl buds tent to look prettier, but the density is with the hps!!!
