I cant find the par value site yet
the last link was just to show that a xenon is infact a mh using same burn temp and metal salts,also that last site was mentioning how a xenon produces light more efficientlly than an led by 3% I think it was. That was to put to bed the notion that xenon is less efficient than a traditional mh. I'm sorry I'm in the middle of a move and dont have much more time for research but im sure if you look you can find the par value site....or you could just take my word for it lol The results were this watt for watt the xenon hid has a slightly higher par value than a traditional mh.
My personal thoughts remain that with a little tweaking this technology is perfect for a nano reef 14gal and under where a 70w halide isnt practical. Xenon hid will never replace mh 70w+ because its the same technology just different firing gases that arent needed in a bigger bulb.
I enjoy debates like this,I hope no one takes me negatively just bothers me when people dismiss something without either trying or researching it first.
The fella here powering his 5.5 is happy with the light he claims no heat issues and looking at the pic his tank is glowing something fierce,his corals look happy and have good p.e. As for the comment that your corals have p.e even in the dark...well duh but try keeping them in the dark for a week
or two (the time he's been running this light) and see what happens lol
