Nicer than mine… Good job, djozz.

I have 3 4070e leds, but saving them for FW3A.

Very nice! Purple light is quite cool. Something different!

Nice build djozz, like it a lot. Cool customization on the bezel, tail and bake.

also liking the XP-L HI throw g_damian.

Got a few C8F hosts to play with. Just haven’t touched them since modding the first C8F I got as complete light.
Thanks for posting your info and specs guys.

I’m just getting back into modding and upgraded a Thorfire TG06S with a FET, XPL2 (4000K) and Efest 14500 (2017 ver).

Not sure how many amps its pulling but based on battery sag and XPL2 Vf, it’s hopefully somewhere around 6-7 amps for 1700 lumens!

Pretty bright for a keychain flashlight and blows my old Astrolux A01 out of the water.

I highly recommend the TG06S as a 14500 modding host/EDC. They can be had for around $13.
The XPL2 die is exactly the same size as the XPG2 it replaced so no need to mess with the reflector either.

Thermal management is OK, but it didn’t heat up as fast as I was expecting. I think the aluminum pill/shelf is a bit thin.

I have upgraded a cheap silver S2+ from GB which had the V21A xpl hi and 3/5 mode convoy 105 driver.
Replaced it with an XPL2 HD 5000K and a BLF A6 driver to make a small pocket rocket, it gives a lot of light, did not measure current draw, but i am not happy with the tint, it’s ugly as hell!
Hot spot is OK but it has an ugly yellow corona which is very annoying to me.

Instantly ordered a XPL hi 4500K 4B from KD.

3.45 × 3.45 mm for both right? Unless I screwed something up (which is common).
The factory centering ring fit just right for the xpl2 so I’m happy Smile
My builds rarely go together as smoothly as this one did.

You are talking about the package size, 3.45 × 3.45mm is the standard “XP” package size.

The die is the yellow part of the LED that actually lights up. The die of the XP-L2 is just about twice as large as the die of the XP-G2 (depending on which version of the XP-G2 you mean, Cree modified it a few times). This means that in the same flashlight the hotspot will be twice as large when you replace an XP-G2 with a XP-L2.
This is also shown be the higher maximum drive current in the datasheet.

That’s funny, I also thought the overall size of the XP-L2 same as XP-G2. Bringing this kind small detail is so educative. Footprint is the correct word, not die. So now I can say that XML has same footprint has XML2 but different die. Thanks for the reading!

In Cree parlance, the footprint is XM, XP, XR, XB, etc. The die size is L, G, E, etc.

So XP-L and XM-L2 actually use the same chip (the L2), but one is in the bigger XM casing and the other is in the trimmed XP casing (you can see the 4 “slices” taken off the dome).

That’s not even counting the XHPs, the MTs, etc.

May I introduce BLF Q8 Janus:

2 Heads, one white, one with red, green, blue and amber LEDs, heads and color LEDs individually controllable.

The modified MCPCB with XP-E2 color LEDs, and my driver which is used in both heads. In the white head populated with FET + 7135, in the color head populated with 4 × 7135 for each LED. MCU is Attiny 841. Full ramping UI of course. The reflector bottom had to be grinded a bit to make room for the outer LED wire pad. Reversed MCPCB polarity (batt+ at the outer trace to keep grinding at a minimum).

Cut a solid 6mm brass rod and soldered a spring on one end in order to bring batt+ to the rear head. Used tape to isolate the rod and drilled a hole in the tail PCB.

The threads at the rear end of the battery tube are too short to reach the driver board so I made cut outs (for the PCB screws) to a copper ring and put this ring on top of the PCB.

Btw., this is how I program my Q8 drivers:

Impressive, can you cap off either end and have it work as a single light or is it fixed in this dual config now?

It’s only screwed and can be separated easily for 2 individual lights. I just unscrew the rear head and pull brass rod and copper ring out.

With the medium amp draw from the meteor it seems like a pretty ideal light for those LEDs.

Wonderful weird project Flashy Mike! Big Smile
That is lots of designing and building!

link to djozz tests 

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)
