Yes it will draw closer to the 600 watt usage then the 1000 watt max.
Can you use a 600 watt bulb in a 1000 watt ballast.
You will need to use the 1000 watt bulbs in the fixture and yes you can dim it to the 600 watt setting.
Yes you can dim a 1000 watt bulb to 600 or 400 and the ballast will only use about 20 30 watts more than the setting it is on.
The up sides to this are the 1000w bulbs are much much bigger so the light is more evenly dispersed in my hood and through the canopy not only.
I ve been using a 400 watt hps bulb on a 1000 watt hps ballast for about a week now.
I am sure that a 1000 watt dimmed to 500 watts 50 will fire a 600 watt bulb.
I was told that a 1000 watt de cmh bulb would work just fine with a 1000 watt de hps mh ballast so long as the ballast is set to 100 1000 watts.
100 75 and 50.
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.
Just to clarify and make this make a little more sense to you guys that dont get it yet just like how dimable ballasts allow you to run 50 500w 75 750w through a 1000w bulb you can also run the bulb just fine on a 600w ballast at 60 its maximum rating.
The difference in the old.
If you have a 1000 watt bulb you need the 1000 watt model.
He said that cmh bulbs will even run on old school magnetic mh ballasts if the wattage is right that basically cmh ballasts are the same as old school mh ballasts.
This will refuce your electicity usage and it will reduce your heat by more than half.
In example if you have the switch set at 400 watt with a 1000 watt bulb in it it will use about 430 watts.
It produces much whiter light than when running on the 150 watt ballast but it still didn t blow up.
Anyway i run a 1000 watt bulb in a 600 watt ballast on my scrog for afew positive reasons.
Yes you can use a smaller watt bulb with a higher watt ballast your bulb will only use 600 watts it won t burn up.
Just make sure to get the model that matches your bulb wattage.
If the dimmer settings arent enough vivosun ballasts also come in 400 watt and 600 watt models that fit most hid lights.
I then put a 150 watt hps bulb on the same 1000 watt ballast.
