400 watt hps brighter than 1000watt hps

wired up my 1000watt hps ballast, put on a brand new Hortilux super hps bulb, and its not as bright as my old 400, whats going on?

it's a different color, more yellow but only half as bright.

did i wire something wrong?

are you compairing them side to side or from memory?

maybe your mistaken

side to side, they are both on

is it the right bulb? sorry for the obvious questions but just trying to cover the basics

Which ballast do you have and where did you buy it? Link?

Where did you buy the hortilux? (thinking maybe someone ripped you off with a used bulb)

Did you leave it on long enough to fully warm up?

bought at a local store. had the light on 12 hours still not bright

noticed was using a pretty small power cable, could that be the problem? going to switch to lower guage wire.

No the cord would have gotten warm or hot if it's too thin... Replace it if it did.

Take the bulb back, it's either defective or you maybe got a used bulb someone already returned.

theres no way improper wiring of the ballast could cause this?

if the polarity was reversed could that cause the problem? i think we jst f'd up wiring the ballast
