Light Turning off...

[revhtree]

Any ideas??

One of my MH lamps will cut off every once in a while for no reason. It's ran on a reefkeeper2 and is set to turn off if the tank hits 82.5, but this is not why it's turning off.

plug it into a new socket w/ a different timer (not on the reefkeeper). this will make sure its not the reefkeeper turning it off.

if it keeps turning off after you do this, may be something wrong with the ballast or bulb...

basically just systematically eliminate the possibilities 1 by 1.

Yea I am sure it's not the RK..

Dang it! LOL!

I would guess the ballast is the issue.

I had a 4 month old set of hammy awhile back and one of them would go out, then when it cooled off would come back on

 

[revhtree]

Yea that seems to be whats happening!

 

[smcooler]

it could be the lamp, if the arc tube gets damaged or overdriven with the wrong ballast could cause the lamp to fail,HTH

Rev what fixture/lighting brand do you have?

I had the same thing happen and i had to change the fuses in my ballast every week until one day it just stayed on and I haven't changed the fuse since.

My was a current outer orbit pro.

These are 250w ARO Elec Ballast with 250w 14k Hamiltons.

my guess would be either the ballast or bulb is over heating

If you have an extra bulb, try it first. It is either you bulb or ballast causing this. Do you have two bulb/ballasts running? If so, try running the problem bulb on the opposite ballast. That should tell you if it is bulb or ballast right away.
Also, if this is a retro make sure all of your wire connections are good.

mine was doing this shortly before my ballast went out.

 

[revhtree]

Well it's the ballast! It is only a few months old from hellolights so I am hoping I am good.

Mine did it when my phoenix bulb hit 14 months. I changed out the bulb 3 weeks ago it has worked great.
