Is the 0D still white after dedoming? Or is there some green or yellow? Thanks!
The 0D actually came out pretty nice, it’s warmer than it was but not obnoxiously so. I like a white tint, white like a high quality bonded typing paper, and while the de-domed 0D isn’t THAT white, it’s not yellow or green either. I hot de-domed it, on a star but free floating and connected directly to a bench test cell, a partially used Samsung UR18650FJ.
Beautiful color,
do you maybe remember temperature (probably more than my oven can reach) of baking and time?
I tried baking an S2+ with almost no change at all… What temp and time are you guys using? Can it be done in a conventional oven?
500f or broil if you have it. Close to top. I’ve seen changes in 15-34 minutes.
Yep, chadvone nailed it. 500ºF for about 30 minutes. I bent a stiff wire and made a holder for the light, ran the wire up inside the battery tube such that the light was vertical, bezel up. Sat it on a cookie sheet.
Pro tip: Do it while any lady friends are away for the day. It makes a bit of a smell.
Naaaa, the ladies much prefer the baked flashlight to my roasting coffee. 
My Lady roasts her own coffee, but if I bake a flashlight she checks the house to see what melted 
Too funy, self justification at it’s finest!
Um, can I assume you actually removed all the flammable bits from the light before sticking it in the oven?
Is that required? That would explain why it didn’t turn on afterwards….
Do you get HA IV anodisation after baking 
I swapped the emitter of my Alu S1 for a T6-4C and also put a T4-7A in my CNQG Brass Beauty (nice very warm tint !)
From left to right : Alu S1 modded to 4C, Ti-Polished S1 NW, Ti-beadblasted S1 NW, Cu-PVD S1 CW, S2 CW, S10 XM-L2 (slightly green), Convoy S2 1A, S2+ triple 219C, Brass Beauty 7A
I did the first of two red S2+ mods, and this was the more difficult one. Not because of what I did, but because of what I was forced to leave out. This is to be a camping/reading light for my girlfriend (birthday soon), and since she does not care one bit about flashlights, it has to be perfectly functional to please her: a soft floody and not too bright light for reading a book, and to find the way from the tent to the bathroom at night as well. Anything more is completely wasted on her :-(
So how can a flashaholic save his pride over this? By using a nice red 18350-size S2+ as a basis. By letting it have a butter-smooth floody beam by making it a triple with a frosted Carclo. By using three Oslon Square 3000K 92CRI leds. By using the simple elegant AK-47-C1 driver (no memory 3-mode, start in low), and removing a chip for just 700mA regulated leftover. By not telling her that with that triple Noctigon soldered to the pill and these leds that are inside her light, I would have had it run at 12amps if she only had shown a remote desire for that.
A nice feature of these S2+ lights that I got recently from Simon's store is that the threading inside the head is going (almost) close enough to the lens that a triple with Carclo optic can be used without needing a spacer (is this a new feature?), I just had to keep the glass lens in front of the optic to make it screwed tight against the front o-ring, and I did not flatten the top of the pill, just soldered the Noctigon op top of the rim (700mA is not going to cause much trouble, but I believe this could handle many amps anyway). A small (phosfor bronze) spring was soldered to the driver and the light was ready to go, an Efest 18350 battery fitted perfectly.
The grand performance 
, on a 700mAh 18350: 35mA/10lumen/20hours low, 175mA/54lumen/4hours medium, 700mA/165lumen/1hour high. The beam about perfectly illuminates a book from 40cm distance, while being directional enough to be used to walk by at night as well. And 20 hours is sufficient to read a book of 800 pages :-) (that is my reading speed, she reads faster than I do).
For the second red S2+ shorty (my copy) I'm glad that I will only be resitricted by my own shortcomings, the leds have not arrived yet but it is going to be a 18500 mod with grossly insufficient heatsinking on high setting :evil:
Very thoughtful of you Jos. We will hope she’s so tickled with it, and your thoughtfulness in it’s build qualifications, that she puts the book away for a while so you can do midnight inspections with it.
Thanks all, I’m baking my S4 tonight, will let you know the results.
Man djozz that’s an awesome build. Where do you get those Oslon Squares? I’d love to make a triple like yours!
You are such a sweetie djozz. Giving your girlfriend something she has no interest in but do the hard work on the gift anyway. Damn you sound like a few others here. Keep up the good work. Who knows, one day she may want a twelve amp output light. Not likely though.
I will have to mod the wifes lights to start in low. She turns it on and uses it whatever mode its on.
Would you not be tempted to make the current a tiny bit more than 700mA?
These 92CRI 3000K Squares are, compared to Nichia’s warm leds, a bit more yellow tinted but the red reproduction is still excellent, very incan-like
I buy the Oslons from rs-online. They do not sell to private persons but I buy there via my work (they let me do that every now and then). It seems that from the US this company is not easy to order from, which is a pity 
Nice light djozz . I will be building a couple simple light as soon as I get my ak47’s back from mattlward, he is gonna try and make them 2 speeds.
Tonight I mobydrv ed my HO2 and gave in a 219c
