What did you mod today?

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. :wink:

My Lady roasts her own coffee, but if I bake a flashlight she checks the house to see what melted :stuck_out_tongue:

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? :stuck_out_tongue:

Is that required? That would explain why it didn’t turn on afterwards….

Do you get HA IV anodisation after baking :smiley:

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. :wink:

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. :smiley:

Would you not be tempted to make the current a tiny bit more than 700mA? :wink:

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 :frowning:

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

My TMW-160F multitool :smiley:
