These work great. And are cheap.

I prefer wide lighting closer to plants. I use 8" raptors and Magnum xxxl's with SE.

Yes I'm definitely going to be ordering a couple extra ballast's and bulbs.

The problem with people blowing there bulbs is there not using a square wave ballast and a 6kvps hood, the standard 5kvps hoods are fine for HPS and MH DE's but not for CMH DE's.

I too perfer a much wider
hood than the small ones that most newer lighting setups come with

There is another thread about the 945's I will look for it. They were blowing on a few different ballasts I think.

Does the bulb manufacturer specify which ballast manufacturers? Or just Square wave?

I find it hard sometimes because they obviously just want to sell product. So much china crap these days and no shortage of BS marketing. The Mags are still way more reliable which is sad.

I thank as long as ballast is a ture square wave with a 6kv hood should work fine, I guess I will find out soon

Okay just to give an update. Growers wanting to go CMH you need to make sure you match your bulb voltage with your ballast out put voltage and not input voltage. You will probably have to call the manufacturer.

Update I have a couple of bulb manufacturers testing there bulbs with different ballast manufacturers. I will arrive in China in April to go over testing results.

Update, all manufacturers of 1000 watt CMH bulbs have failed testing. Will need more time to improve the bulb.
