can i use a 200w e40 envirolight in a 400w hps ballast??

HI ALL I NEED A LITTLE HELP!!!......................

WELL IVE GOT A PLANT HAPPY IN 8TH WEEK FLOWERING UNDER A 400W HPS (NEEDING ANOTHER WEEK OR 2) AND I WAS WOUNDERING IF IT WAS A GD IDEA TO PUT A 200W E40 ENVIROLIGHT IN THE 400W BALLAST TO SAVE ON ELECTRICITY SINCE I LOST MY JOB AND SKINT AS THE QUEEN. I PUT IT IN TODAY AND IT ALL LOOKS GRAVY??? WHAT DO YOU ALL THINK GOOD OR BAD IDEA.???????????

bad idea, stick with the hps.

bad idea major fire hazard, the bulb could blow up for having too much juice pumping into it.

We just went thru this last week, lower wattage bulb inn a bigger ballast should cause the bulb to explode.

On the other hand putting a larger bulb in a smaller ballast is supposed to work.

We can't get 100% verification of this but have found enough to make it believable.

If you want to put the bulb in and see if it explodes we will know that at least we are 100% on that question.

Aren't envirolights those large cfl's? That would be sooo cool to see what would happen if you tried to run one of them off a HPS ballast.

If it makes any difference i think its a self ballasting bulb in which case im no expert but it will run perfect straight from mains electricity (plug), so its going through a ballast reducing it to 400w then the bulb again reduces the electric to whateva it needs. Is there anyone knows from experience.

i know from experience that if you put things where theyre not supposed to go, bad stuff usually happens

just plug the bulb straight into the electric using a lamp lead and avoid the ballast.

no.no.no.no.no.no.

so in short theory stick a plug on the wire where i'd usually have it in ballast??? sorted. can't beleive im that skint i cnt afford to finish a grow with pride haha. thanks for the help boistly!

two weeks work of 400w hps lecky aint gonna be shit, just use the HPS to finish.

just buy a lamp lead, there not expensive at all.

completely agreed with Mammal, I don't see you saving that much money by doing so. finish off with the 400w hps.
