Better manufacturers include Lumen data for their lamps (even the incandesc=
ents.)
Most of the PAR38 150W bulbs I see are significantly less than 2400 lumens.

Can you replace your fixtures with twice as many smaller ones?  150-W-equiv=
alent LEDs seem to be pretty rare (and =85 power dissipation issues!), but =
"75W equiv" bulbs are common (in the US, anyway.)
