sanjay's lighting info gives the geisseman 13k mega marine a par of 92 on an HQI ballast. the XM DE gets 60. That beats out a 250W 13k like the aquaconnect (62 par on an 250W hqi ballast).
When my bulb needs to be changed I'm switching to the geisseman mega marine. I had one before in a DIY HQI light and it was frickin' bright.
