Hey guys, this is my first time---well, actually using on my second grow cycle---but I was previously using it single bulb at 315 watts.

Last night, i unplugged the ballast and inserted the second unused bulb. Waited for 8 oclock for lights to come on. . ...and nothing.

B.Lite 630 watts CMH. I don't see any external fuse slots. Ive plugged it into other outlets, still nothing. Switched the bulbs, nothing. Took out the newer bulb and back to the original usage, still nothing.

Just wondering if anyone is experienced with this fixture? Any help would be nice, thanks guys.

Oh BTW, the burnt looking bulb is the newer one. The not-burnt looking one has about a thousand hrs on it.

If its in circuit.
I do not have that brand ballast but from everything I have experienced, the dud or burned bulb will keep the other from firing. I was never able to run mine at 315 only 630. And if one went out, the whole fixture wouldnt fire.

I guess, if you were able to run a single, do you remember what side it would fire on? Try both bubs. Sorry not much help here, all my nanolux 630's would only fire when both bulbs were in and working so maybe this brand is different. Hence my comment. Hope you figure it out.

Yeah unfortunately i went back to the original working setup with the working bulb, nothing. Tried the other socket, nothing.

Have you checked the cable from the ballast to the wall the IEC320 cable. I've experienced where those are fucked even though they look fine.

it's likely either the cable. Or the ballast is dead or finally both the bulbs are dead. I recieved 6 Phillips bulbs from different online orders and only 1 of them worked out of the box without having to do a return. I think it's cuz Amazon are wankers and just drop the bulbs at the door.
