I think Sofirn looks great in silver and then I wouldn’t have to use drain cleaner!

How difficult is it to strip the anodization with drain cleaner? Any good tutorials online?
Id like to strip my iPhone.

What’s inside this drain cleaner? I would also like to strip the anodisation of some flashlights like this.

Sodium hydroxide. Very corrosive alkali that eats aluminium for breakfast. Be careful or you will consume the whole light into aluminium hydroxide.

Thank you, Lumen9000. Do you know how it could be done without damage to the flashlight? If I quickly wipe the flashlight with the sodium hydroxide and rinse it with water afterwards? Just asking because I have been looking for an easy and fast method to remove the anodisation to make a flashlight silver.

Jackie, is this silver version bare aluminum, or is it clear anodized, or coated in any way?

I must say that after I got SP35 NO ATR I got spoiled by High mode and Turbo. Everything with ATR or timed stepdown is a no go for me and that's why I just couldn't buy IF22A although it intrigued me a lot. 

@Barry: I hope you'll reconsider this driver option in the future.

The process is simple but has a lot of precautions. It needs to be done outside and heavy gloves. Aluminum and sodium hydroxide create an exothermic reaction and can cause burns on the skin or inhaled.

So with that said it is easy and straightforward. I used a gel based drain cleaner which I found much easier to control than the crystals that get dissolved in liquid. After taking out the battery, I painted the flashlight with the gel and put it in a ziplock. The anodization came off in several minutes and was very quick. The o-rings, rubber boots, glass is fine (although I avoided the lens because I wasn’t sure of the coatings in the glass. That particular flashlight is pretty water resistant so there was no ingress with the gel. I rinsed the light for several minutes in water. I did the inner threads and any spots I missed by painting the gel and and repeating the process.

I like using the gel, other people have had success and like using the liquid or the crystals that dissolve in water. I use lye to strip cast iron pans and restore them so I am comfortable enough with it. I won’t use any of this stuff in my plumbing and honestly I have no idea where the bottle even came from. IDK how your drain cleaner selection is in Europe or access to chemicals is, but I used the Prof Amos with success.

The best option would be to have a programable option in the UI to turn ATR on or off. Or you could add jumper pads to the back of the driver that toggle ATR.

I would probably buy the IF22A if it had the SP35 driver. I’m actually surprised that it doesn’t. Too bad.

Or, just use anduril and set temps preferred.

How? 

I'm not a programmer BTW and I like SP35 no ATR UI, sometimes more than Anduril

You just click it in a special order and voilla! There are very helpful short anduril set temp videos explaining how to do, takes a minute or two. :)

Oh wow! So IF22A is coming with Anduril?????

No I don’t think that’s officially mentioned anywhere, but I sure hope they’ll release an IF22A version with Anduril 2

Still…simple SP35 no atr driver in IF22A, i’ll take it anytime over Anduril.

Will the new SP40A TIR be available in the green anodize? Can I swap this TIR into my older green SP40?

Hey Jackie,

Loving the silver IF22A, would you happen to have a code for Shopee?

Would love to get my hand on one.

Thanks

The SP40A is very interesting.
Will Sofirn sell the TIR optic alone?
