|Modes:||3: High, Low + hidden strobe|
|LED Type:||3 x XM-L T6 3C (NW)|

|Date Ordered:||March 2012|
- Bright!! (-er than my DRY!)
- Available as NW
- Good runtime with four cells
- Side switch (suits this format very well)
- Well spaced modes
- Hidden strobe
- Tailstands well (and can be used to illuminate the whole room )
- Good build quality
- Nice color (something else than "normal" black / silver)
- Comes in a nice box, lanyard included, suitable for gifting!
- PWM on low mode (~200Hz)
- Positive pole of the cell needs to be smooth, or it carves the metal from driver board (see image below)
Features / Value: ★★★★★
The light comes in a nice package:
..which contains the light itself, nice lanyard, one extra O-ring and a manual (of some sort - Chinese only!)
Features are good: Two well spaced modes (about 2200 and 300 lumens OTF), nice electric side switch (reverse clicky) and hidden strobe in case you should need it.
UI is good: No memory, so the light always starts on high, which is the most used mode in this kind of light. Another click and you can enjoy the low mode - third click to turn the light off. Strobe is initiated if the switch is pressed two seconds when the light is on.
If anyone is worried about the electronic switch turning on accidentally, I can comfort you by saying that the light can be locked out simply by unscrewing the head about 1/8 - 1/4 turns.
FX-32 and DrJones measured the parasitic drain, which was 1.5mA, which can be considered negligible (with four cells totaling about 10Ah), so no problem there either. Thanks to both of you for helping with this important measure!
Value for money: VERY good. This must be currently the best 3 x XML-L budget light!
Design / Build Quality: ★★★★★
Design is nice. Short, quite thick and with side switch. Fits my hand perfectly and at least I like the side switch better than DRY's tailcap switch.
Color is a matter of taste. I hesitated at first, but have learned to like the color very much. IMHO the color looks even better in real life. [Maybe the Enzo Ferrari "syndrome" kicked in: "The car is beautiful when it wins" -> "The light is beautiful when it's brighter than competition" ]
The anodization is good overall, glass lens looks nice, and the switch feels as good as an electric switch can feel, so let's see some details..
Cooling fins and the electronic switch:
Three well centered NW emitters, ready to push out some serious amount of lumens:
The threads were smooth, but very dry - requires lubing. The O-ring is well placed and it keeps in place very well:
A look to the inside. Four cells in a smallest possible formation. Nice! Also longer cells like XTAR 18700 fit fine without any problems.
Note the scratched metal on the driver board. It was caused by a sharp edge in the positive pole of some of my XTAR cells!
And please ignore the small dents in the end of body tube - they were caused by my current measurement actions..
Another photo with the cells inside the body tube. This shows how the positive poles are pressed against the driver when screwing the head to the body.
Head diameter: 59mm
Body diameter: 50mm
Tail diameter: 54mm
Weight: 531g with 4 cells (= ready to use), 341g without
..and here's two pictures confirming the measurements:
This light is actually unbelievably short, for example when compared to DRY:
And the bottom line in the quality: Absolutely nothing to complain! Surprisingly good in all aspects!
Battery Life: ★★★★★
Good! Four batteries will allow fairly long runtimes.
I tried to measure the current and got results of 5.2A on high, 0.45A on low. [NOTE: The wiring required for the test might cause the result on high to be too low, especially when comparing it to the output (and measurements on thaicpf)] Edit: Re-did the measurements: about 7.5A on high and 0.65A on low. [But I think the wires were still restricting the current. Most probably this monster is eating somewhere between 8A and 9A]
This would give almost 1.5h runtime on high, and over 15h on low!
Light Output: ★★★★★
This light is a bit brighter than my DRY NW, so I would classify this as "very bright". Ceiling bounce was measured about 10% higher than DRY on high, and the beamshots below seem to confirm this.
There is some thermal sag, but less than with DRY in Turbo mode, especially the first 10s were bad for DRY. The big body with nice fins seems to take the heat quite well!
Ceiling bounce figures for a five minute run indoors, ambient temperature 24 degrees Celsius (DRY Turbo vs. King High):
After the five minute run the DRY was "almost too hot to touch". King was only "hot", significantly cooler than DRY.
I estimate (ceiling bounce + "known" references) the light output to:
- over 2000 lumens on high (maybe around 2200-2300?)
- about 300 (or a bit less) on low
Beam intensity (measured at 4m, calculated back to 1m):
DRY NW Turbo 20.1kcd
King NW High 22.7kcd, Low 2.7kcd
Two white wall beamshots (WB: Daylight)
Outdoor beamshots (Distance 90m, camera settings: 70mm, 1.3s, f/8, ISO400, WB 4800K)
Comparison to DRY NW on Turbo: (Mouse over for Skyray King)
Very good flashlight with nice finish for anyone who wants to put out massive amount of neutral white lumens.
This light is actually my new favorite 3 x XM-L and has replaced the DRY NW in most cases.
The End (pun intended):
Thanks for reading & watching. Hope you enjoyed the review!
