The bulb completes the circuit and makes the ballast run off 400 watts.
Can you put a 600 watt bulb in a 1000 watt ballast.
The bulb didn t immediately blow.
The dimming does hurt the overall life of the bulbs in the long run but really 2 or 3 grows on a bulbs is about the max you want to really put on bulbs anyways.
I ve been using a 400 watt hps bulb on a 1000 watt hps ballast for about a week now.
But to put a 1000w into a 600w ballast pry wont work or could blow up in your face or burn your house down if you left it running.
100 75 and 50.
I then put a 150 watt hps bulb on the same 1000 watt ballast.
I am sure that a 1000 watt dimmed to 500 watts 50 will fire a 600 watt bulb.
You will need to use the 1000 watt bulbs in the fixture and yes you can dim it to the 600 watt setting.
If you have a 400w you can put a 430w in an hps ballast.
Are you guys just saying all this cuz it sounds crazy.
A ballast can throw as much as 1000 watts but only when needed to the bulb controls that what dont all you get.
I was on ebay pricing 600 watt ballasts and i noticed on one of the 1000 watt ballasts that the dimmable amounts were in percentages.
Or digital ballast where they have a 1000w max and dimmable to 600w and 400w with the 1000w bulb.
I was told that this works with ballasts like my 1000w de phantom and 1000w de sunsystem ballasts possibly with my 1000w nanolux but that isn t tested yet.
It produces much whiter light than when running on the 150 watt ballast but it still didn t blow up.
Yes it will draw closer to the 600 watt usage then the 1000 watt max.
