I love these little baby 1 x AA Ultrafire C3 hosts they are so cute..

I bought the host off eBay, The heatsink and focus adapter came from Moh (think I he closed up shop before it arrived).

EDIT: Rayfoss sent the replacement sled to compensate me for the PHR in the original sled. Unfortunately it was also a "fake" S06J. The sleds were marked as "Manufacturer Refurbished" and had the blue dot on the diode as in the BDR-S06J group buy thread. Stay away from Rayfoss.

I am feeding it with about 115mA using the original Cree driver that came with the unit. It was putting around 350mA into the white LED, so i looked up the data sheet & started mucking around with resistors, turns out the ones already in it worked fine with the higher diode voltage drop. It's driving about 95mA at 1.5V and 120mA at 4.2V. I have tested it up to 7.2V (2 x 14250's or 1/2 size AA's) and the driver only gets warm at 7.2V after a minute or so.

I am very pleased with this, hope you enjoy it:

Obligatory beamshots. The first two are from my daughters Samsung - it seems to capture the colour better. The last is from my Canon A720:

The C3 build nice small build. I also like the host a lot.
How do you know the BDR-S06J sled is fake ? I would file a complaint against Rayfoss :(

The diode I got was the same as in this thread, Blue dot, three pins soldered etc. I didn't discover the scam until I had removed the diode from the sled, so probably no warrant on it now but I will tell everyone I know not to buy from them...

EDIT: The new sled arrived and again it had a PHR diode in it as per this thread. Not so happy now. They did have it listed as a "Manufacturer Refurbished" on eBay.

UPDATE:
I emailed Rayfoss and they asked for pictures of the sled they sent me. That's when I saw the PHR-803T sticker on it. Rayfoss have agreed to send me the correct sled.

Good on them for admiring liability and I am very happy and they corrected the mistake to my satisfaction :)

Blast! I had this exact build in mind! Same exact set up! Beat me to the punch! If only my 803 came in sooner :whistle: Oh well..
Nice job on the build! Looks great! I hope mine comes out as well as yours!
+1!*

*when I can... I need to spread some around first

Thanks for the rep-raincheck lol.

One thing, you should watch if you want to use the existing driver, stick with the a single 3.7 V to 4.2 V cell. The laser diode in this LED'd on Friday after I switched it on with the 2 x 3.6V 14250's in it. I think the initial startup voltage on the driver is a bit high running at 7.2V.

I'll put another one in with a better driver or use the host for a BDR diode I have coming.

Nice build, I'm going to look around to see if I can locate a host like that.
