【convoy】SFT40 5000K back in stock (sufficient)

How did that light perform ? I need a IR light was looking at the Z1.

Can you show a photo of your modded Z1 with 4x IR?

Quite nicely :slight_smile: going all the way from super floody to the ‘LED’ picture on the subject , got the 4 LED pcb and driver here : https://fr.aliexpress.com/item/32996731684.html
I’m not a big fan of zoomy, and the Z1 is quite bigger than I really need, that’s why a S2+ would be better for me, but I was too lazy for the mod.

yeah, next time I use it :slight_smile:
it’s nothing fancy, I had quite some trouble reassembling the head though (the o-ring messed up a few times)

Don’t bother showing me then, no need to take it apart again

Thank you for the link, that’s what I needed.

What range roughly are you getting?

Is there a way of removing the AR coating from the glass on my convoy s2+?

I have the convoy s2+ with the 219b sw45k emitter and I noticed that when I remove the glass, the tint looks slightly better. When lighting up white objects with the glass in place they look a little green, and I suspect it has to do with the AR coating.

Scrub, scrub, scrub.


With what? And how do I not scratch it?

Lots of previous posts on how to remove AR coatings. One of which is what LB just mentioned. I advise you to search.

Same principle like using a razor to scrape your old registration sticker off your windshield. Glass might be brittle, but it’s incredibly hard. Steel wool works nice, but it’s tedious to do, and you gotta get both sides if it’s coated on both sides, too.

DON’T use sandpaper of any kind, not even fine grit, as that is harder than glass, and will frost it.

I only tried it (steel wool) because I was okay if it’d frost it, as I’d likely be using diffusion film anyway if I wanted a flooder. Wasn’t an S2/S2+, but I vaguely vaguely vaguely recall it was one of the older Sofirn SPs that had AR coating on the glass. Might be mistaken, though.

Anyway, it came out fine, enough so that I can’t even recall which light it was. Ie, not “damn, I ruined the glass on that light…” or anything.

Sit back and veg out watching teevee while doing it, as it’s tedious and takes quite a while.

Thanks Lightbringer :beer:

Ima get scrubbing!

Hey Funtastic whats your plans?
I was looking at buying a Z1 and fitting one of those 10w 850nm IR led into it and see how it goes as I think my IR is the weak link with my old scope.
Before I go out and buy a new NV scope for my new Air gun “rabbit hunting”. I would like to try a better IR light on my old trusty Photon XT.


As my IR “sensor” is a cheap mini-“action”-camera, I can’t use it at more than 50 meters (the camera doesn’t show anything useful further): I mainly use it as a very close range flood light
You may get 100-150m, but I can’t tell…

Hmmm, okay, no good for me then. I need something for 300-350m for my store, I was hoping the L21B would be capable, but maybe not.

I wonder if Simon would ever consider the Vscel IR lasers. That’s entirely unfamiliar territory for me though.

yes, suitable .

i have normal glass lens ,
i can send you some for free in your next parcel if you need it

Convoy S12 with IR LED,infrared 850nm when will they be available ?
Can you make me a Z1 850nm also?

Are you listening, Simon? I hope you are.

Many people dislikes anti-reflective coatings. I dislike them too. This is because the standard anti-reflective coating used for flashlight lenses is λ/4 MgF2 centered at 550nm, which being centered at 550nm, a frequency of green, boosts this frequency and those around it more than the remaining frequencies in the visible spectrum. This can be seen in the following graph chart at Edmund Optics:

In the above graph it can be clearly seen how the λ/4 MgF2 550nm curve is lowest around 550nm, and goes higher (higher reflection, or less effective) around it. Therefore, the gains of this AR-coating are unbalanced and noticeably screw up the tint and even the CRI of emitters to some extent.

What does this mean? Many customers would buy plain lenses anytime, lenses without anti-reflective coating. Customers of high-CRI lights and emitters, namely.

Hope this is of service.

I use Sunshine Cloths to polish the coatings off.

I am using JoshK "Delete Green" paint on all Convoy lenses.

Well not all, i have a few without coating.
