Looking for PAR info on the 250 watt DE phoenix bulb...

[golfish]

I'm looking for some info on the PAR of these bulbs ran on the m80 ballest..
I understand that there are more things in play here, I'm just looking for basic PAR ratings.

Thanks

Kind of weird way to do it..but a start..oh and used electronic ballast.

Just a bit more cut from a thread

My reading with a 250 watt DE Phoenix 14K read at the light around 700+ but only a few inches below water it drops to 150 or so. The light is about 12" above the water.
(Ignore this, just put in for reference on the bottom part.)

. I've looked at the Sanjay site and he shows PPFD at levels of 125 or so when the meter is 18" away from the source.

a lot of Sanjays stuff is "lost to the ages" so to speak. Some can be found using the "wayback machine" internet archives.
