70w mh has trouble firing...
 

i'm running a 70w mh with an electronic ballast, and it seems like it never wants to fire up by itself,...i hear it trying, and nothing...so i take the glass out of canopy, and make sure the bulb is sitting properly, and then try it, and it fires up....

what the hell is going on?

so i tryed what i normally do, then i just ended up giving the fixture a few nice taps as it was trying to fire up and BANG there it went...anyone know what could be causing this? the bulb maybe??

if you have a current light...some of the bulbs arnt burnt in right at the factory.....email them and they will send u a replacmentment free.:razz:

What kind of fixture are you using? Maybe the bub isn't making a very good contact on one of the sockets.

I'm gonna guess it's an ARC ballast, save some headache, aromat ballasts are available on ebay. I gave up on my ARC, not worth the hassle sending it back repeatedly.
