Review: Skyray King (3xXM-L - 4x18650)

Awesome review _The_....One question, are the three reflectors for the KING the same size and depth as the DRY? 5.2a on high mode is amazing!

Thanks for putting all this together to share with us.

So because they're in parallel does that mean it's sucking 5.2A from each cell? That would be ridiculously too much for the XM-L. It would basically be counterproductive. Although, I don't quite know how to translate 4 cells powering 3 emitters that are also in parallel. For my feeble brain it seems like it's overboard.

No, total input current is 5.2Amps (in the’s measurement) that means that the current divides into four because they are in parallel. One voltage, four currents. In this case, each cell gives around 1.3Amps.

This is an important review. I don't regret buying the Dry but if I had it to do over again, I would gladly pony up the extra $20 for this 4-cell powerhouse. This form factor is hard to make pretty but the King almost manages to do it. I love how the tube is cut round for the batteries and the side switch is to die for.

Better looks, higher quality and the piece de resistance; mo lumens!

So I have to cycle through low and strobe everytime I want to turn it off? That may be a dealbreaker for me. My Coleman MC-E does that.

No, you would just cycle through low mode. The strobe mode is sort of hidden.

Although, I don't like the concept of cycling through any modes to turn a flashlight off. It seems clumsy to me. And with these budget lights I'd rather not have an electric switch. It just seems like there's one extra thing to go wrong.

Just think of it as a double-click when in High and one click when in Low :)

YOu could be right about the switch though. That's what putting me off too

Nice _the_ review.

IMO 5.2A = 1.73A per LED(not include other factor ),still too far from 2000 OTF. May be something wrong about measurement or anything both Sky Ray King and DRY .

Someone measured Sky Ray King is around 1600-1800 OTF.

1.73A in bare lumens would be 600, for the XM-L T6 efficiency bin. So emitter lumens. Now we need to take into the consideration the reflector and the glass. That will cut a certain percentage from the light. I would go with POK's 1600 lumens estimation.

Is it not possible to just measure the current draw on one 18650 and divide that by 4? Or is the current draw on 1 cell too high?

And at 1600 lumens, it can't be brighter than the DRY on Turbo then but according to the's pictures, the King is brighter.

That is our estimation based on the current, which is not a precise one, as the current reading itself may not be precise.

My flux estimate is nearly 2400 lm, so I think each LED gets >3A.

But how are you obtaining that flux estimate? Light box? Lux meter? Power draw?

Both torches are CW. Looks like DRY still has the lead to me, which is inconsistent with most tests so far from the and drjones.

Damn, some great pics there!

Not sure should I or shouldn´t I...

Well, it would be interesting to make a measurement with that integrating sphere and compare it to my previous DRY´s figures.

I re-did my wiring for current measurement and got now results from 7.0A up to 7.7A, which might be nearer the real value. [I'm still not sure about the wiring.. It might still restrict the current a bit?]

Holding the wires and operating camera at the same time isn't easy, but here's some kind of proof of the measurement:

And as I was at it, I thought that I would measure the beam intensity at the same time (@4m, calculated back to 1m):

King NW High 22.7kcd, Low 2.7kcd

Added the following to the review:

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.

Amazing! How´s that possible? 8)

Driver-efficiency or just plain raw bulk on cooling?

between this and dr jones, sounding like driver, and maybe even cell? efficiency
