You may already know this, but "lumens" can be misleading. From the Wiki: '
The difference between the units lumen
is that the lux takes into account the area over which the luminous flux is spread. A flux of 1000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1000 lux. The same 1000 lumens, spread out over ten square metres, produces a dimmer illuminance of only 100 lux. Mathematically, 1 lx = 1 lm/m2."
IOW, that LED is claiming 7-8000 lumens across 140 degrees--which is one hell of a wide spread for that much brightness. Maybe 10-12x more than the typical "flashlight" beam, considering it goes by square not linear spread.
