Where did you get the LD30? I ask because prior mentions and pictures here indicate several variations on that are out there.
Mmm. I like waffles.
Now that is a very sexy light you’ve made there MRsDNF! I like the shape of the head.
Looks wonderful… sure wish I had those skills! But, I really want one of these drivers. What is the draw with a single AA?
Amazing.
I know it’s a boost driver, but I still can’t get my mind around how its powering four XP-E2 with one AA? I try to do the math in my head, but unfortunately, I have a small head.
Did you have to file the 24mm optic down to fit?
What is the other XP-E host, and what are the lens dimensions. I’m looking for AA hosts that take a 20mm optic.
Thanks guys. The driver is this one.
The output is identical with either one or two batteries.Using one battery on a run time test output dropped from a starting measurement of 785 to 737 after seventy minutes at which time my pillow was calling. After turn off the light always starts on low.
I should of mentioned that the MCPCB sits on a solid three mm shelf. The head is all one piece apart from the brass bezel. The 17mm driver is soldered into a 18mm adapter which is pressed into the head.
The clip is a Titanium one from the Rey light, Titanium BLF light, as you could buy extra’s at the time. The long clip I normally use which is on the other AA light here was to long to fit on this light. The Rey Titanium clip works perfectly on this light allowing the light to be clipped to the inside of my pocket.
Tailcap measurements from my totally uncalibrated DMM using Turnigy LSD 2400 mAh batteries were,
Single battery, low .02 A, med .25 A and high 1.58 A.
Two batteries, low .01 A, med .13 AmAh and high .65 A.
The light is slightly brighter on high with a single battery on my light measuring device.
My review on the driver can be found here.
Edit. I should mention that the difference in readings would be attributed to the power supply used during testing and a different DMM used for the measurements.
The LED’s are wired up so they are all in parallel. If the driver is putting out its advertised .5 amp each led would be receiving 1/4 of .5 amp being .125 A. Not a lot hence I’m not sure if this light would be Dale approved. 
Of your not the only one with a small head as others here will tell you with the many PM’s I’ve had to other members trying to understand things. :disappointed:
This light was specifically built around this optic. The X^ Monster light Dale sent me was made by him before he had a lathe. He used his exceptional skills to make an adapter to fit the optic into the X6.
The mini C8 can be adapted with a pill to accept the 22mm optic. This uses a AAA battery.
As far as of the shelf hosts go I haven’t bought anything for specific uses like optics etc.
Wow, that’s really good! Especially powered by AA. Any beamshots?
Third picture is a beamshot. Seriously though I’ll try and get a few tonight.
Another gorgeous build, Steve!
great work as allways, enjoy that well earned holiday …
Great build!
Does anyone remember this smiley
O (“_” “O” ““) is sure fits here but the ”” is used for italic
Wth a single nihm on high giving you a tail reading of 1.58A would mean each emitter is running at 0.395A…I think….
Even though that doesn’t seem like a lot, it should push those XP-E2s nice enough, for how long is for you to find out.
That’s a nice little light, Steve.
I nearly came up with an idea for that quad board today, whilst under the influence of paint thinner fumes from trying to de-dome those damn Oslons…. :confounded:
Not really. The current from the NiMH has to be converted to voltage to turn on the LED. That’s why the tail-cap draw of the 2xAA is lower.
David is correct. The 1.2 volts of the battery has to be boosted to the voltage the led requires + whatever the voltage the driver need so 1.58 A at the tailcap probably equates to around .5 amp output divided x four as the LED’s are in parallel.
You had me laughing FmC. Did you do any good?
Night shots will be in the first post shortly. Dont scroll down to the last picture to quickly. You know how it is with Dales lights. 
Not sure yet, as I haven’t had time to put one in a torch…. I think I must have lost about three hours wondering aimlessly around the back yard…
Very desirable little light,especially the one-battery set-up. Very useful too, indeed I use my lights mostly under 500mA too.
Sweet build MRsDNF. Always dig your creations.
As the others said, Nice build! Good to see you cutting chips again.
