This evening I got a call from DHL courier saying I'll get a package. Sounds great! I wonder if it's from Ric, since I haven't got the tracking number yet.
Let's see what it contains..
Ok. Two BTUs. Hmm.. Let's open those small boxes..
Whoaa!! They do exist!
First impressions (and a bit more - I bet you are too anxious to wait for the full review, so..)
- These things are small!! (see comparison pic at the end of this post)
- Some 18650s won't fit. The length is not an issue, but thickness may be:
- Panasonic 3100mAh didn't fit to either of those
- XTAR 18700 2600mAh did fit to other, but got stuck inside the other
- TF flames do fit, same as unprotected NCR18650s
- Tube inner diameter is 18.80mm in one, 19.00mm in other
- No PWM
- Nice tint in both (not green at all, despite of being current controlled!)
- Bright enough, still not overdriven
- Gets hot on high
- Nice low mode (could be even lower for me, but this is good for most)
- Good mode spacing
- Modes are L-M-H, no memory (resets in 5s)
- CW is brighter, as it should
- "Titanium" color looks good (different, not gold, not black)
- Anodizing looks good
- TIR optics seem to work well (a bit ringy spill though)
- Threads were dry, requires lube (especially as being a twisty)
=> Highly recommended (just make sure that your cells will fit!)
Some measurements:
Length: 91.5mm
Head diameter: 24.5mm
Tail diameter: 22.6-22.9mm
Inner diameter: 18.7-19.0mm
Weight: 39-41g (83-85g w. batt)
TC currents:
NW: 0.05, 0.55, 1.90A
CW: 0.05, 0.55, 1.90A
Lumens (OTF):
CW: Initial 650lm. After 30s: 530lm, 200lm, 15lm
NW: Initial 550lm. After 30s: 450lm, 180lm, 14lm (some minutes later: 430lm, very hot)
And finally some more pics.
