Playing with TK41 Beamshots

LED Flashlights – General Info
1

I wanted to experiment with some longer shutter settings like they use at fonarik.com but my camera does not do too well at ISO 800.

So I used 13" shutter speed and f14 (instead of f16) to compensate for the ISO400 that I used. Light and camera were sitting on the back of my red Mustang, so you don't get a full 360 degree beamshot as the spoiler and body sort of cut off the lower spill.

This is the TK41 on Lo, it is almost a control shot

Medium brings out real light

Now the TK41 on High

And on Turbo

This is a shot angled the opposite direction down my driveway. That bright white thing to the left of the tree is my mailbox post, almost 250 feet away. Turbo mode

Thanks troop!

3

Wow. You think the TK41 is brighter than the HD2010?

4

I would think so but since I don't have the HD I wouldn't be able to say for sure. Anyone here have both?

5

My favorite flashlight. Nice pictures Troop.

6

I'm with you guys. The Tk41 is my favorite flashlight. It does everything except fit in my pocket.

7

Well, it fits but it spooks my wife when I carry it like that…

If you have the possibility, could you measure how much lux TK41 throws at 1m on turbo?

10

I don't have a meter that will do that, maybe someone else does.

It is the best thrower I have, but I don't buy muilti-emitter lights or multi-18650 lights.

Has same reflector as the HD2010 and should be same brightness maybe. That's why I wondered if a difference could be seen.

I didn't found lux@1m for tk-41 anywhere, but found a test for tk-60. It has the same head (or it looks like the tk-41) and the light output values are very close with tk-41. So just for info, TK60, Turbo - 45,936 Lux @ 1 Meter
