Well, from what I have learned here, Don has said that a light designed to work only with 1.5V current is more efficient and will be brighter with alkalines and NiMHs compared to a light running 1.5V that can optionally handle >3V. This is an advantage for me, since I don't use 14500s.
I don't know, the only other XP-G R5 light I currently own is the Trustfire R5-A3, and on 1.2V NiMH it really is insanely bright. Could very well be 200+ lumens.
Mine got 115 at switch on with NiMH, 292 with 14500. The NiMH test might be on the low side and will be redone to get the 30 sec and 2 minute measurements.
If you own the Trustfire R5-A3 and you truly want "insanely bright", you need to try it on 14500's. To my eyes and others, it becomes about twice as bright.
I have brighter - it's close to 3x as bright at switch-on - if I were prepared to push the voltage higher it would just about touch 300 lumens at switch on - it gets 117 or a bit more with an NiMH.
Mine has only had an NiMH in it for testing. It is indeed a real screamer on 14500 and doesn't set fire to your hands like the C3 stainless steel.
After grabbing the image and doing a brutal unsharp mask in Photoshop, it is possible that it is an XP-G - the image is too murky to be certain but there appear to be 4 segments.
There is not really enough data in the image to be certain.
As fran82 said, if there are three dots visible around the die the emitter isn't an XP-G and it wouldn't be the first time DX failed to list correct specs...
Whoa, nice catch Fran82! Well, there goes a lot of the appeal of this light. Shame on DX and Eastward YJ for their deceptive advertising. I updated my first post.
I actually cancelled my order when I found out about the deceptive advertising of the claimed XP-G emitter at DX. The company (Eastward) appears to be willing to do custom modifications, we'll see if we can work something out with them.
Yes, I was looking for the model on their website, and I can't find it either. Appears to be very new. I searched all over Google, and I couldn't even find it on the chinese trading sites.
