Sometimes we don't get what we pray for. Sometimes we get much more.
I will be ordering an
XR-E neutral Q4-5B (3.6v - 8.4v) 3 Levels
PM sent. Ready to send PP.

Received mt XPG dropin today. Just want to say it has one of the prettiest beams Ive ever seen. Almost perfect for my taste. Lots of throw with plenty of flood.
Oooh. Got my R4 today and quickly installed it in a SF 6P. Excellent beam quality and lots-o-output. More flood than my R2's, but I'm not comparing apples to apples WRT reflectors.
This is my second drop-in from Dave and I've been impressed with both (the other was a MC-E). I think I need a SST next...

I see all the dropins are 6v max.
Any future plans to make something in lets say a 12v capacity ?
I have single level to 18 volt @1.4 amps I had to have those made.
There really are few options at the amperage you all want the leds ran at. These 8.4 running at 1.2amps are the first I have been able to find.
There are 12 & 16 volt that the flashlight manufacturers use but most of the time they are 800ma to 1amp and that is it.
Is it possible to stack 2 or 3 converters? For example, I have an Aleph LE (DatiLED) with 2x SOB917 drivers, putting 1.8A to the emitter. It's a DD LE, and really honks with 1.8A. Being a buck, it takes much more voltage, and provides extra drive current for the hungrier emitters.
The biggest problem is finding a driver that is 17mm to stack. I just stacked two 1.4amp for Sgt to get a full 2.8amps on a SST 50 but of course it was 6 volts since they were 6 volts. My 1.4amp drives that take 18v are too tall to stack.
Even the flashlight manufacturers have an option I dont' they can design the can to fit larger drivers.
The sob are too small for these modules, sharks too big I keep looking, I am actually trying to get the 8.4 amp made with no flashes on the low super low but it is vacation time over there.
Does anyone, who uses these with 18650's, have an idea how long they run?
say sst-90 or mce? and does the head gets hot after 10 minutes, for example?
I just picked up a FiveMega 3 "C" cell body/clicky.
I figure 3 rechargeable C cells fresh off the charger would be just a tad over 12v.
This body is compatible with Surefire 6P heads, so I was looking for a dropin that would take advantage of those large C cells as far as max output(Great throw) and runtime go.
We could do a 1.4 amp one level XPG or any led that we can run at that amperage. The one level as stated are good to 18v.
I also could wire a MCE 2S2P and then that 1.4 amp driver will run the MCE at full power. I made a mag for big chelis wire that way with that driver and it is very efficient and quite bright.
After that I am about out of options
The 1.4 amp one level XPG sounds really good.
Roughly, how many lumens are we looking at?
Will it have decent throw? I love throw
What type of runtime do you estimate on those 3 c cells?
I did a couple like this for two members and the out the front was measurement was 350lumens.
As for throw I like the throw of it but some as you can read
think it has more spill than the R2 which may be the wider viewing angle the XPG has.
I can also use a R2 XRE /XPE or this new XPG R4. I myself think it is a good mix of the two.
It is here! I need to shoot you a PM.
Paypal sent for one D26 SST-50 module, smooth reflector, L/M/H functions, powered by one 18650 battery.
of all the new offerings to date is the XRE R2 still considered the best thrower?
we exchanged emails about 2 weeks ago regarding the XRE R2 being the best thrower you have, but now I'm wondering about the XPG R4. can it out throw the R2?
i'm looking for the best thrower available: smo reflector?, 1 level (max output), regulated, SF 6P host (i have one bored for 18650 if i need it)
what would work better for this application: 2 x rcr123 or 1 x 18650?

for the XP-G on my pill/pedestal setup.
thanks for your time on the PMs'..
It is just so subjective, I would say you can't go wrong with it. Alot of the folks think the XPG is more floody and with the wider viewing angle it probably is but I myself think it ranks with all of them XRE,XPE, XPG but that is just me.
They are all very close in performance but the R2 XRE pushed amp wise very well could be.
PM sent re single stage XP-G and shipping to Australia.
XP-G R4, single mode, 1.4amp. + Int shipping
For SST-50, 3 level, no strobe, as per our PM.
(Dave, you can thank PSM, he talked me into it)
I prefer to have the OP reflector for that SST-50, not the smooth.
(actually a VLOP reflector would be great if possible)
