Size comparison with TK11
The walls are pretty thick
Reflector size comparison.
From left to right: Romisen RC-P3, Olight T25-T, Fenix TK20, Fenix E20, Fenix L2D 100
Runtime is slightly shorter than advertised.
I have some troubles with correct white balance. I usually use Fluorescent-H, the LEDs look the most realistic with this setting. But TK20 looks too red (or too yellow or blue with other settings). To my eyes the Fluorescent-H white balance is still the most accurate. Just remember that it is slightly less red in the real world.
Some white wall beamshots with other lights:
Some garden shots:
Fenix TK20 - Olight T25-T - Fenix TK11
Fenix L2D Q5 - Fenix E20 (spot) - Romisen RC-P3
And the last comparison with Olight T25-T
The rubber grip - has a good grip
but when changing modes via twisting the head it has a tendency to roll round the body so you have to hold the light firmly (i hope this sentence is understandable
). Doesn't affect the real world usage by much but Fenix should solve this issue.
The throw is great, comparable to Olight T25-T, Streamlight Scorpion LED C4, or TK10. Much better than L2D/L2T/E20.
IMHO this is overall very good light. Tint might be too warm for someone but I think that especially incan guys should like it. But it wouldn't be bad if Fenix made Premium R2 Wh version. Probably it would be the brightest 2xAA light available.
