【convoy】H4 and B35AM options are updated

If someone want to have minimal or much less spill compared to a reflector flashlight, TIRs could be a good option. I think, it cannot replace a Convoy L2, but could be very useful - it is just a different beam shape.

I tried an S2+ with 10 degree beaded TIR lens with XP-L HI and Luminus SST-20 high CRI emitters, and it is very spectacular. XP-L HI (and probably other domeless emitters as well) was even better with narrower TIR lens. An S2+ with 5 degree clear TIR lens is even more spectacular in this regard.

Could you please have a look at LEDiL TIRs (I don’t know your possibilities about how to find a good retailer for their optics, but it might worth a try)? :slight_smile:

The Gaggione LLC49U is the narrowest throwiest optic I have found in the size range. If you can put this in a flashlight, you will have a very unique hand held spotlight. I like how optics can concentrate all the lumens into the hotspot instead of “wasting” half of the lumens as spill. Putting a Oslon CLSNM1.TG will achieve 175kcd or more with a larger more usable hotspot in a Emisar D1S size light.

Since I already have enough floody/spill lights now, intensed focused hotspot is what interest me.

Honestly, are such TIR lenses as good as you seem to believe? I bought some narrow beam (5°) inexpensive TIRs for S2+ flashlights, but didn't liked too much the end result. Compared to a wider angle set bought from FastTech their ceiling bounce lux figures were noticeably :!!!: lower.

Aspherics all the way! :-D

I want to ask if the 15% BLF discount is also available for the Black C8+ Host?

Pretty sure it applies to all items in the store except for the basic shipping cost when you ask for replacement parts like lenses, switches and such.

for furture designs the 21700 cells seem to be good to get a slim light compared to 26650 lights

Wow,this link is very helpful ,thanks so much ,

yes,friend

i’m so interested in the combination of Gaggione LLC49U and Oslon CLSNM1.TG,
is it possible to send some photos or link to show the performance?

Im also curious to see what a narrow optic with a white flat will do.
21700 s2+ with quad white flat… where do i sign up :+1:

At SKV89
Do you know if it is possible to fit the Gaggione LLC49U inside a C8+?

Will it be possible to buy the M1 SMO reflector in your store. I ordered another M1 Host a few days back at BG. But it would be nice to be able to buy the SMO reflector for it.

I highly doubt it because optics are usually shorter than reflectors. Also the optic must not be resting flat on the mcpcb and not on the positive/negative leads in order to focus the emitter so the mcpcb might not even be suitable. I think it will be hard to just use these optics in an existing flashlight unless you are really skilled and can machine or 3D print your own parts. I think in order to use these successfully, a manufacturer will need to design the flashlight around these optics.

I downloaded the 3D files for the LLC49U. The outer diameter is the first problem. It is a little bit to big. And you would have to grind it to far down to fit. So this would be the first problem.
To raise the MCPCB /LED would not be a problem. But i do not know if a usual MCPCB would fit. Have not checked yet if they offer a special design for this.

For sure a interesting project. But not something for the C8+. Will look further into the optic and what they recommend regarding the MCPCB.

i add a link here

Thanks for making the M1/M2 SMO reflector available!
Already ordered one.

About new SST-20 option mentioned in OP - what are the exact tint and bin?

BIN: SST-20-W40H-A120-J4402Rev.01 J5-FB4-VH

I did the same with the same results. But there’s a difference between a cheap Ali lens and a Gaggione one.
One could ask Gaggione to provide cd/lm on this lens/LED combo. They once run a simulation for me, they would likely do the same to a prospect buyer.

The CLSNM1.TG may work very well with Led Lenser imitation type TIR optics.
They have a relatively large aspheric in the centre so it can focus the light into a narrow beam, unlike most other TIR optics.
You find these optics in cheap 3xAAA lights too, sometimes.
But maybe the diameter is too large for an S2+
But then again, i’ve seen smaller diameter versions too.

With typical 20mm TIR optics, the 5° ones often have no aspheric lens in the centre. They’re just flat in the centre.
Then they act like a normal reflector: beam from the cup and spill from the centre.
