bought a torch with Cree XM-L T6 led emitter, claims to have 1,800 lumens
while in practice probably has around 1,000. The light beam is almost as
bright as the headlight of the car, clearly illuminating treetops across my
yard, some 50+ meters away. I have no slightest idea if that is sufficient,
will see that in a few weeks. But the light is bright enough that I would
not look into the beam, tenfold that sounds like a dangerous thing?
