UDO - My measurements are OK. I also am very sdhfkjsdhfkjs of what is happening, specially about 1,8A current draw for 14500 and only slightly increase in output
The PCB of mine is RED too, the same pcb as always, "sandwich" driver, you can see 3 solders which join the 2 boards
Just made this two pics into gif. Both were shot from 2m away at iso 80, 1/25s, f2,8. Brightness comparison between ni-mh and li-ion in Skyray S-A1, both batteries were fully charged:
I have looked at this light for so long ..Old4570 liked this light too .I've meant to buy this one for a long long time ..lets do it ..I can wait 3 months for them to send it ...why not !
Someone can tellme how to correct those BIG images and put thumbnails or more adecuate sized?

To go back and re-edit them just highlight a pic in your post, then click the insert/edit image button and look on the second tab called "appearance". There you can type in the size you'd like. I usually go 640x480.
Very nice review Fran, that's an impressive output level for such an inexpensive light. Thanks for bringing it to our attention. Hmmm, so no pocket clip and no tailstanding. Those are two very important features for me, unfortunately.
Hmm, bright on Eneloops you say... I wasn't impressed with the two I had looked at, when they were on sale for small money on DX . Every one of the 8+ Hugsby's P31/P32 I checked were brighter. You must have a new driver version.
Hugsby P32 left "old" Skyray SA-1 right (look how much dimmer the side spill is)
(pic has an angle to it, beam radii are the same, distances from wall are the same, both on "fresh" eneloops)
But...... the dude is. Mine is brighter due to a possible new driver revision? or yours are not bright due to QC issues? There is the question.... chinese cheapo lights..... that has happend to me with other lights. I order one light on January, it is good, I order the same light on June, is bad.....
It wasn't just one but 2 Skyray's, that would mean that there was (or is? beamshot was made November 2010) most likely a complete batch which is considerably darker on Eneloops than the Hugsby's. Just a heads-up for potential buyers. Here is the old thread about them back in 2010.
Also your estimation of 150 lumens (OTF) with 1.5 A (on the tail) strikes me as very optimistic. The theoretical ouput with a perfect driver and no loses is 120 Lumens. (1.5 (tail) /3= 0.5 A , Q3 at 0.5 A (to LED) ~120 Lumens) Either your DMM needs a calibration or you are using China-Lumens. ;-)
Yes, somehow I am using china lumens. I dont know the exact amount of lumens, I only can confirm that is about 30% brighter than all the other lights I have (F20, AA-S1 etc)
My multimeter is working perfectly, I have checked and rechecked it measuring other currents I know and no difference. Also I changed the battery and the measurements are the same
Dons UniqueFire AA-S1 needed 2195mA to reach that 100 Lumens on NiMH and your Skyray is 30 % brighter at only 1.5 A ? Something still is weird. I had very similar effects when I used the inferior leads on my Voltcraft 91 DMM (cheapo 10-15$) and when I used a 100+ Euros Metex 3630d I had up to 0.5-0.7 A higher current readings. What DMM are you using? Do you have the possibility to cross check your DMM against another one?
