My HPS lamp has been turning off every ten minutes, an unwelcome pattern I just noticed. It goes off for about 30 seconds and stays on for about 10 minutes in intervals. Does this mean I need a new bulb? New Equipment? Its been kinda hot and rainy here lately, I don't know if that makes a difference. There also has been several power outages due to some thunrderstorms in the past couple of weeks. I've also been noticing some stretching with my k train and wasn't sure if it had to do with genetics, but now I think it may be my faulty lamp. Please give me some good and swift advice so I can save my ladies!!!

sounds like it could be an issue with the ignitor....just a thought.

try a new bubl if that don't fix it get a new ballast.

is it a light that you purchased, as in it is basically a light you can buy at home depot for lighting up signs and such. if so then it has a photocell imbeded on it, and it will sense light, so once it gets so bright it senses it and turns off. and the process repeats.

solution: find where it is sensing it(normally a swirly little circle) just cover it with something dark.

obviously the ignitor is working because it lights it up to begin with, try setting a fan up to cool the ballast off, if that doesnt work then get a new bulb and you should be good to go.

start with diagnosing the problem and check it off. trial and error :)

Sounds to me that some kind of thermal protector is activating - maybe inside the ballast.

A lot of these ballast assemblies have the ignitor and other bits inside the case housing the ballast. Makes replacement of duff components difficult and often expensive.

I prefer to have a separate magnetic ballast and the ignitor wired externally to that.

And if the bulb is lighting up OK, the ignitor is probably sound.

Aloha !


IT IS THE LAMP


When a lamp starts to fail iy cycles , the interval will get shorter and shorter

When an igniter fails, the lamp won't start.

Well the lamp has the ballast built into it, I got it from HTG Supply. I had a fan blowing air on it and thought that might have been the problem so I took out the fan, but waited 30 minutes and noticed it clicked off 3 times. I just started using this lamp 3 months ago even though I got it 2 years ago, I had it in storage since I wasn't using it. I will go ahead and buy a new bulb. Thanks for all the advice.

Another question, can I just purchased a 250W HPS bulb from home depot instead of ordering one online and having to wait for it to be shipped? Or do I have to use the specific SunAro Max bulb?

you dont HAVE to get that exact bulb, you CAN go to lowes or home depot and get a 250watter, but the ones that you can buy online(that are typically more expensive) are spectrum enhanced, meaning they emit more rays of light that your plant loves.

I just got back from Home Depot, and decided to do away with my HPS and switch to CFL's, They only had 3500 K Cfl's so I got those. Hopefully less heat will be generated.
