And I seriously don't think 240000 lumen will light up a football stadium...
EDIT, a rough calculation: I found here in some FIFA-pdf that a decent lighted soccer-field for national games needs 2500 lux on the grass (3500lux for international games, and there's a bit more to it, quite fun to read the pdf). Say that an area of 7000 metersqr. needs to be illuminated, than that equals to 17,500,000 lumen, that is 875 Dale/OL-monster-lights.
oh
thank to you to informed me about dale
excuse me to i had mistaken
dale is great flashlight producer and assembler
i read the lighting football stadium pdf that have a lot of scientific information about how to brighten football stadium in perfect bright
17,500,000 lumen is great ultra illumination may consume a lot of energy to produce that
may be individual powerhouse need to provide power to bright on lights
i if can ,i want to buy Texas poker to experiment it
if to bright of 7000 meter square near sun shine you may use calculate the luster
in 80000 lumen per each meter it mean 80000 x 7000 equal to 560,000,000 lumen
to bright football stadium near noon time sun shine in summers long day
that all human in that place feel sweat!!!!
