This is a link to a thread on RC that is very detailed and very comprehensive, its on 250 single ended metal halide bulbs. And it encompasses just about all of them. the neat thing about it is that JBNY, (the guy doing all this work) is comparing all the bulbs with different ballasts, so you can see how the different combinations effect PAR. I hope we canget JBNY over here. He had just started posting over on RAG, when everything got crazy.
Important things to note....
1... JBNY doesnt work for anyone in the industry, he's just a hobbiest like you and me. He's doing this for knowledge and enjoyment of the hobby, (altho I suspect he quit enjoying these tests somewhere after the second month of steady testing bulbs and ballasts!)
2...This testing only encompasses 250 watt Single Ended bulbs. He's not comparing 400 watts or the 175watts, just the 250's. I dont know how much things will translate over to different wattages...(ie, if bulb Q gives off a PAR rating of 600 while being fired by ballast X in the 250 watt configuration, the same combination in 175 watt configuration wont necessarily produce a PAR rating of 525)...and JBNY doesnt even begin to try and draw correlations between his tests and other wattages.
Basically this is a great thread for those interested in learing alot about the different bulbs and ballast combinations and how they can effect your animals.
I hope you guys all find this interesting, I certainly have...
