terralux 300m not a lot brighter than a TK10?

[Barrie]

hi to you all
i got a terralux 300m for my 2D mag to run on 6xAA
i am waiting on the AAtoD holders coming from KD so thought to try out the terralux i would try my 3AAA to C-cell holders
so put in 6x1000mAh rechargeable AAAs and of i went on a night walk with my dogs for a hour to try it out in the dark
i was a bit surprised to find out it is not much brighter than my TK10 when tried side by side could this be that the AAAs don't deliver enough power:thinking:
or is that as good as it gets considering the TK10 is rated at 225 lumen's and the terralux 500-600 lumen's i thought there would be a noticeable difference to the eye

Probably too much internal resistance and/or voltage sag. 6xAAA is not exactly a stellar power source.

also, the 300m is 600 lumens over 3 leds, 200 each then, in a single spot the TK would be the same, if your in the woods the floody terra would win hands down illuminating everything. where as the TK is bright only at one spot.
I have a 200 lumen kd q5 mag and out in the open fields its the same as my terralux too.

It's difficult to make comparisons by the eye because of the TLE-300's hotspot-only hybrid beam. Your TK10 probably throws a much smaller hotspot about the same distance, but you have to note how wide an area you're illuminating. The Fenix provides a lot of nice nearby flood, which the TerraLUX doesn't have at all, all its light goes straight forward.

The easiest way to see the difference is the ceiling bounce. When you shine a flashlight at the ceiling of a darkened room, the room as you see it is now lit only by the *total output* of that light - you've removed the element of beam profile and can now see, at least roughly, how much light is being emitted. The test goes something like this; Standing in a pitch black room with two flashlights you want to compare, you shine the first light at the ceiling - you have to shine it in such a way that you can't see the end of the flashlight itself or the beam profile, so pointing it up near your ear works nicely. Now you're seeing the room lit by the total output of that light. Next, close your eyes, turn off or cover light one and switch to light two, and open your eyes - is the room brighter or dimmer? The answer will reveal which light has more *lumens* regardless of *throw*.
