Had time for a wee cracker mod before starting the Christmas dinner today
Yeah, we just donât 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
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!
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-L2âs 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, itâs big brother (SP32A) also a side clicky, makes almost 1900 lumens from itâs factory XP-L2.
I got the 5700K V6 from Arrow. Yes, there is some discoloration as weâve seen from XP-G3 and now the XP-L2, the flip chip technology and all that, BUT, Iâve 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.
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 havenât 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 inâŠ
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 resultâŠ
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. Iâm 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 Iâm off to find out why⊠love these little XP-L2âs. Just ordered 25 of them in 5000K from ArrowâŠ. 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.
DBâŠdo you have beam shots of the Xp-l2 lights? I wanted to order a bunch but seriously worried about the tint. I donât 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.
