Its MV and I ordered this through a distributor back in 2001 It originaly was 175 watt with the PBP optical (the larger one) and then I ordered a R.P replacement ballast and door from Surplus City about a year ago and at the moment its 400 watt MV. I only had it installed for about 2 months and decided to change fixtures on my pole......You know me.
LOL I see. 400W with that reflector? must get HOT! I personally don't know why they offer plastic lenses for power brackets, highbays, and lowbays. IMO it should be glass...
Yes they do the PBS (smaller lens) is for 175 watts and below and the PBP (larger lens) is for 250-400 watts both are plastic. and I won't put a 400 watt lamp in with the SKYGARD it won't fit it hangs out the bottom about 4 inches, I bet it would get extremely hot problebly melt.
