1. Olight S1 copper, bare, with no coloring on the bezel/button/clip, and a 4700K to 5000K emitter (Nichia 219B high-CRI, 219C, or XP-L HI 3D). Preferably also a battery check mode instead of a timer (blink out cell voltage in volts and tenths).
2. Why? The S1 is a great little light (one of the best), but it doesn’t currently come with the right combination of bare copper and neutral white tint. The S1’s domed XM-L2 produces a rainbow effect at different parts of the beam, which would be reduced by a Nichia 219 or an XP-L HI. Also the only way to tell if a cell is low is to take it out and measure with a multimeter, so it would be nice to see voltage without removing the cell. Coloring on the steel parts is nice at first, but scratches off over time — bare metal would keep its appearance longer. Bonus points if the internals can be accessed fairly easily for emitter swaps, driver mods, etc.

Another light I’d like:
1. AA or 14500 cell light with size and shape similar to the CNQG Brass AA or L3 Illuminations L10, with a Nichia 219B high-CRI or 219C inside, and a driver which is easy to take out and reflash with a SOIC8 clip and usbasp programmer. Preferably also made of bare metal, such as titanium or copper or brass or non-anodized aluminum. I could even provide firmware for it, if desired. Preferably also a nice clip; Olight has some of the best deep-carry clips.
2. Why? Small AA-sized lights hit a sweet spot for size and shape and capacity. However, there are very few which are designed to be taken apart for modification. I would love to see more small AA-sized lights available for the community to modify and improve, and I also want to get some more advanced interfaces running on smaller lights. It would be nice to have a small AA-sized light with the BLF A6 or “bistro” interface, for example. Or, if it had an e-switch, a quick smooth ramping interface.
I’m trying not to get into too much detail here, but can provide much more information and source code if desired.

I don’t really need the i3S-CU. I just wanted to put out a couple ideas for new lights.
