MAGLITE 3 D

I have received some e-mails and PM’s asking me to do a beam shot of the maglite 3 D, a light that is very popular in the law enforcement circles and with outdoorsman.

The light is billed as outputting 39 lumens; this is true with fresh high quality D batteries; however as alkaline batteries sag a lot under load, this output is maintained for only seven minutes, when it drops to 75 % of the output.

After one hour, the light is doing 50 % of the output (or close to 20 lumens).

Yes, I know this is probably a surprise to many fans of this light, so here is a chart that will explain graphically what I just wrote.



Here is the beam shot, from 26 yards and coming from the second story window, as always my deer and bear are at 12 and 18 feet from the camera.

Maglite 3 D 39 lumens (fresh, new batteries)



And here as a way of comparison, the
BOREALIS 1050 lumens (made on the same 3 D body)



Cheers
