400w hps dimmable ballast

[TheAmuck]

So i was using this ballast for my last grow but In the last week it'll shut off when I put in 100%. I had at 75% for 5 weeks then went 100% for the end then I noticed it turns off could this be the lamp ?ballast?or is it pumping too much power for my outlet, btw the fan inside the ballast stays on after the lamp turns off

I'm just wondering if I should buy an new dimmable ballast or lamp

What size bulb are you running? When I dim I have to use a 400 watt but on boost I use a 600 watt

It's a 400

Sounds like a bad bulb. running it at 75% may have shortened it's life span.

Okay cool man I'll be replacing soon , its I was tripping out it work fine for 5 weeks then after it started shutting off, I has been using this build for a couple cycles to -?

Yeah I've had this problem many times it's the lamp that needs replacing

I would replace the bulb and see if that fixes it. You don't have another bulb to test it like an mh, you just run hps?

Na just hps it only stays on when the ballast is on 25% or 75% so it's working now but once I hit the 100% it switches off I'm hit the droe shop manana
