HPS ballast, MH bulb

[suver569]

I've read that a 400W HPS ballast will run 400W MH bulbs (overdriving them to 430W I believe).
Anyone know if a 150W HPS will run 150W (or 175W single ended for that matter) MH bulbs?
The ballast is a Universal HPS, part number s150mltlc3m if that helps.
Thanks for any info.

what is teh ANSI # of the ballast you are looking.
Some Merc Vapor Ballasts will run the Sakis, as they are auctually a Merc Vapor, rather than a halide bulb.
