Had time for a wee cracker mod before starting the Christmas dinner today 
Yeah, we just don’t stop 
The DQG Hobi ti dual, with an XP-L HI emitter on one end and an Amber XP-E2 on the other, powered by two 10250 MBI Nukes. Thanks to kiriba-ru for the optics 
CRX is just incredible guy…
Merry Christmas to whole BLF!
I dimmed down my Q8 side button leds by swapping resistors from 33k to a 100k. I only had 0805 size resistors to play with, so I had myself a challenge :person_facepalming:
But all ended well!
Looks good zipelgas. Solder can be very flexible when you need it to be.
The little Sofirn SP10B was making 590 lumens on a 14500 Li-ion cell, really quite good. And 270 lumens on an NiMH AA. I got some new XP-L2’s in today and wanted to see what the tint is, so I put one in this small light.
Now the NiMH makes 496 lumens and the 14500 does 1070 lumens, pretty much doubling output across the board (Turbo, anyway) Tail amperage shows 2.10A on the little light. Pretty neat getting 1,000 lumens from a small 14500 side clicky light!
By the way, it’s big brother (SP32A) also a side clicky, makes almost 1900 lumens from it’s factory XP-L2. 
Pretty neat that just an emitter swap can double lumens at same current.
So how was the tint of that XP-L2? More specs on it?
Damn, if I’d get some 14500s this might very well become my new EDC.
How fried-eggy is the beam with the L2 in there? That’s a flip-chip, neh?
My living room :
Stock driver and mcpcb?
What xp-l2 did you get? I have a 3c bin and it’s more purple for 5000k than I wanted.
Nice lighting, that is an incandescent lamp or you used some very fine tinted leds
I got the 5700K V6 from Arrow. Yes, there is some discoloration as we’ve seen from XP-G3 and now the XP-L2, the flip chip technology and all that, BUT, I’ve found that if the phosphor that is outside the emitter die surface is removed (that which is on the substrate surrounding the die) then most of the discoloration goes with it.
Thanks Dale, definitely will try that.
As a flip chip, there are no bond wires… makes it easy to do a vertical slice beside the die then remove the outside phosphor without disturbing the emitter.
( I haven’t done this to a light that I intended to keep the dome on, usually sliced the dome off first then did the dicing and outer removal.)
Oh, forgot to answer… I cut a 16mm Noctigon down to fit snugly into the small light . It was slightly larger than 14mm going in…
CFL, they were already in the house when we bought it.
Now, it’s 8 GU10 LED spots :
Stock driver right?
How did you cut the noctigon down?
Just ran the edge across a belt sander holding it vertically in my fingers. A bit of a twist as each pass is made, about 3 passes and cool it off before the fingers get blisters. Rinse and repeat for desired result…
Yes, keeping the stock driver for compatability with AA/NiMH/Li-ion
Hi everyone. Today, I did something big (for me). I soldered the MCPCB directly to the flashlight pill. So far, I did it once by soldering the MCPCB to the S2 + pill. But it was much smaller, easier to warm up. Today I did it with Astrolux SS. The first thing I did was change the default ground to a noctigon. Then I put on a solder paste and screwed the pill into the pill. I screwed on the reflector to check if the diode is sitting evenly. Unscrewed the reflector and started warming up the pill. It lasted a bit, because I used hot air, I do not have a gas burner, but I did it. Now I can feel that the flashlight heats up much faster. I’m happy with the effect.
Last night I tried an XP-L2 in the little X5 with a 14500 cell, dang thing makes 2062 lumens! So today I stuffed 3 of em into an X6, charged up my VTC5 cell and it does 3763.95 lumens, which seems a bit low actually. So I’m off to find out why… love these little XP-L2’s. Just ordered 25 of them in 5000K from Arrow…. the sale is on thru the 29th so ya better hurry! (10off coupon gets 10% off and orders over $20 get free Next Day Air!) Yes, I got 25 XP-L2 5000K for under $3 each.
Probably the voltage drop under load, as well as heat.
The hotter the LED gets the less it outputs.
DB…do you have beam shots of the Xp-l2 lights? I wanted to order a bunch but seriously worried about the tint. I don’t mind the tint shift, but my 5000k v4 3c bin has a pretty bad purple tint at the center. Just wanted to know how the arrow batch of xp-l2 are.
Thanks
