the M81 is a Hqi ballast for 150 watt.

I think from what I recall they are nothing more than colored glass. I will see if I can find out anything for ya.

If you read down they also list a recomended starting voltage, which means you need to put a starter on your ballast also.

another thing I have noticed is that they are listed as having a wave length of 465nm so I am trying to find out if this is a Peek value or a average.
