I'm afraid this is not bright enough for anything but examining normal pupils.

If this had a glassbreaker I'd be all over it.

SokoThis is designed for patient examinations. Being able to have the light not change the true color of the tissue being looked at is a big deal. Doesn't neeed to to be real bright as you are looking at objects very close.

how can 4.2 lumens = 950 lux? Did you mean 42 lumens? Seems like 42 lumens is a more likely figure for a product like this...

SuperSumoYakuza I'm no expert on this, but I understand that lux is a measurement of intensity. If you consider that it's listed as "Beam distance: 950 lux at 20 cm" (slightly under 8inches), I think that's kinda plausible.
Using this lux-lumens calculator (http://www.ledstuff.co.nz/data_calculators.php), to work out their specs backwards, to get 950lux at 20cm, with a 4.2 lumen source, the beam angle needs to be 21.5, which looks plausible. If it was 42 lumens, it would then be 9522lux at 20cm.

" One lux is equal to one lumen per square metre:1 lx = 1 lm/m2 = 1 cd·sr/m2. A flux of 1000 lumens, concentrated into an area of 1 square metre, lights up that square metre with an illuminance of 1000 lux. However, the same 1000 lumens, spread out over 10 square metres, produces a dimmer illuminance of only 100 lux. - https://en.wikipedia.org/wiki/Lux"
