problem with light PLEASE HELP

In my veg room i am running 2 400 watt MH on timers. Both lights are brand new from HTG. Only used for 2 weeeks. So yesterday when the lights came on i went into my veg room and only one light was on. So i looked at the other light and it was off but you could see like a little glow inside the buld a blueish color. Well i unpluged the light for about an hour and pluged it back in when i went to work i came home and the light was on. So when my lights came on today i went upstairs about an hour later and only the one light is working. THe other one will come on like 1/4 strenghth one time and then turn off and stay off. It is still currently not working and is plugged in. Does andyone know where the problem is. By the way i put a $2000 order in at HTG and have already had to send 2 ballasts back and now this.
Thanks for the help

return their crap and try another company? didnt you get paranoid ordering from an actual grow company? thats a pretty quik way to get nabbed i hear. did you walk in to buy em?

i have my medical card and the town i live in cops dont give a shit as long as your in your limit. BUt i am trying to figure out if its the bulb or ballast or whatever the fuck could be wrong with it i need that light right now

Just to throw it out there, it could be a timer problem. Always worth checking

appreciate it but both lights are on the same timer and the other one works fine. they were both working fine for 3 weeks

It could of been the light overheated,or a power glitch.I use this:http://www.discount-hydro.com/productdisp.php?pid=78&navid=5

that sounds like a bad socket maybe they got really shitty equipment dude if you had to return other shit that might tell ya something. You might try just leaving it off and unplugged for a little then try to opperate it manually when you need to turn it on and off and see if that makes a difference

when did u handle lights with ur bare hands? sweaty hands produce oils that are bad for hps lights dat i know but never had mh
-any exposed wires?

just trying to help

The oil thing can just make large lights explode but I have never seen that happen anywhere ever in 20 years of trichomes sticking to 1kw lights and not exactly staying on top of cleaning them.

On the OP's problem... Did you give them time enough to fire or walk in immediately when the first fired. One may just take a little longer. The very first thing to do is tighten that bulb in the socket. I can't count the number of people who just didn't put it in tight enough and so they wouldn't fire but would sort of try. Happens all the time.

un plug the ballast....unscrew the bulb with a glove or something over the bulb as to not touch it with your hands....now look into the socket...theres a little metal thing that touches one side of the bulb when its screwed in...use something to bend that up a little like on a 45 degree angle than get your bulb and screw it back it...even when it feels in give it a few more tries as to push that thing back down to fit snug to the bottom of the bulb...fire it back up and wait 5 minutes to see if it starts...my 400w does that sometimes...they also turn on in stages...going from flickering to dim and than to full throttle...try this and let me know if this helps..;.if not id say that those assholes need to do a refund!!!......ive had lots of problems with hydro equipment....probably a whole bunch of stoners makin the shit...he he he...shhhh ....happy tokin!!!

is your timer rated high enough 2 fire both 400s? make sure your timer can fire both at the same time it might not be able 2

Not clear, but it sounds like set "A" works fine and only set "B" is giving you trouble. If that's the case, carefully pull the bulbs out and switch them - that will tell you if the problem is just a bad bulb, or if it is somewhere else in the system.

Come on, it ain't rocket science!

i would try seperate timers...

i know the timer you are talking about, i'm thinking one of the plugs on that may be for lower current appliances...
