Looking for Radium PAR Data.

Looking for 400W vs. 250W comparisons with same reflector ballast setup.
If you know of a good link to some Radium data let me know.
I have the Sanjay 250W link.
If you have personal data please list the reflector and ballast info.

 

wish i had some 400W info to give you... but i believe that i have thrown this one around before Testing 250-watt Single-ended Metal Halide Lamps and Ballasts by Joe Burger - Reefkeeping.com for 250W

I think the main difference for the 400W is that since it has more PAR being emitted, the intensity penetrates deeper.
If you find some PAR values for 400W please post the link

 

Thanks dingo.
I did find this one from Marc at melevs reef:
Melevsreef.com - PAR Measurements Taken
Some numbers that I wanted to see since he uses reflectors and bulbs I may get. The link you provided is good for comparing those bulbs. I would like to see a 250w radium test with reflectors and deep tank.
