DX (Reviewed Apr 9th 2008)
Throw: High 9500 lux Low 1800 lux (1 x 3.7v 18650 @ 4.15v)
OLD Lightbox: High195 lux Low 36 lux (1 x 3.7v 18650 @ 4.15v)
Intro
- It's a 2 mode 18650-only light that is very bright and has solid feel.
- It is overall a bit smaller than the DBS V2. Same length as WF-400.
Build Quality
- Uses a silver core Cree Q5. Not sure what exact bin code. Neutral tint.
- Textured aluminium reflector. Thick 37mm glass lense. Flat rubber seal.
- 2-mode reverse clicky with resistor. Tail stands though not 100% stable.
- The clicky isn't that easy to press without using the tip of your thumb.
- It uses a standard looking 3 way clicky switch. Feels nice and solid still.
- Nothing seems glued. Cree Q5 is on a star base screwed on to pill.
- Pill easily rotates out. Big copper-like pill. Seems very easily moddable!
- Finish is great. No faults. Perfect square indents on the head. Quality!
- Grade 1 anodizing has a good thick "feel". But it scratches still...
Light Output
- Beam is clean. Big and wide bright spill. No distinct artifacts/rings.
- Hotspot is quite tight and well defined. Very bright hotspot. No holes.
- This light can throw. Even if it's an OP reflector. It does a great job.
- I was able to light up building tops in Sydney CBD over 150m away at night!
- Light tint is very good. Not too white. More neutral to warm tint.
- In Low mode, the output is significantly less. But it's not super low.
In Use
- Fits protected 2500mAh Trustfire 18650 without any issues. No rattle.
- Gets quite hot after about 15 minutes of use. But it's still bearable.
- Runtime graph is very similar to the DBS V2 graph. Similar output also!
- Comes with a decent man-sized thick round lanyard. One hole in tail.
- In low mode, it runs for over 7 hours of super constant brightness so far.
- More exact low mode runtime will be tested when time allows.
Final Notes
- It's an excellent 2-mode 18650 LED torch for this price. But no HAIII.
- I give it 4 stars coz it's extremely bright and well built but not the best.
- Mny report that it gets too hot and possibly killing the emitter coz of it!
- FYI - Eastward
YJ-18WD /
YJ-18WF has HAIII but is same price!
UPDATE
- The Cree emitter is now not as bright as before. Output is halved.
- Pulls same current (~1.5A) from battery still. Just the LED is half-dim.
- Either driver is killing the LED over time or I'm unlucky on the Q5 emitter.
- I've now put in a replacement Q5. All is good again and super bright.
- My Fenix T1 did the exact same thing within 3 days. Bad batch of Q5?
- Wolf359 also reported the "dimming" effect. Seems to be common???
RECOMMENDATION
- For those who are inclined, try improving the heatsinking of the LED.
- By dismounting the star and applying thermal paste on the bottom of it.
- or.. Use it up to ~15 minute bursts at a time. Over an hour is not good.
◎ Measurements
- It pulls 1.50A from 1 x 3.7v 18650 @ 4.15v
