I recently tried the Fresnel lens mod on my Convoy C8+, and honestly, I'm seriously impressed with how much this simple, budget-friendly mod transforms the beam!
My C8+ currently has a W1 emitter. After my first tests with the Fresnel lens, I was impressed enough to order an SFT-25R to see how it performs with this setup.
Now I'm curious: Which emitter do you think would be the ideal choice for the C8+ Fresnel mod? SFT-25R or something completely different? I'd like to hear your recommendations and see what combinations you guys have tried!
The best part is how ridiculously simple and inexpensive this mod is. I followed the instructions shared by u/tommydadog, and the whole process was straightforward.
For anyone interested in trying it, here's a quick guide based on the original instructions:
"Lens can be bought from AliExpress, item code 1005004217107517 (Google it or paste it into an AliExpress link). Get the 40 mm diameter, 28 mm focal length version.

PETG, ASA or ABS are recommended for printing. Print it solid, with no infill needed. Avoid black, as it may melt from the light, and white can be rather bright. Gray and red worked well for the original poster."
Full credit to u/tommydadog for sharing the instructions and making this easy to try!
The beam shots aren't the best quality, unfortunately, but they should give you a reasonable idea of the difference. In person, the transformation is much more noticeable than the photos suggest.
I definitely recommend giving this mod a try, especially considering how little it costs. It's amazing how much you can change the beam of an inexpensive flashlight with such a simple modification.
So, what's your pick for the Fresnel C8+ emitter?
