I really like this light, but I’ve always preferred the beam profile of the earlier SP10 as it’s less ‘floody’.
If you want to tighten it up equal to, or better than the original, go to Kaidomain and get their 18x12 reflector #S021652 and 5 mm gasket #S024680. I didn’t have any 5mm gaskets so I cobbled something up; proper gaskets would no doubt be better.
The head will sit a bit high (by 0.5 mm or less; it still looks far enough over the O-ring to seal well) but you might want to thin the back of the gasket with a bit of fine sandpaper.
The improvement to the beam profile is very noticeable, the hotspot is now roughly the same as the Skilhunt M150 with no rings or artifacts. I’ve ordered more reflectors and gaskets, and next I’ll try sanding off the rear of the reflector by 1/2 mm or so to regain the original dimensions. The two I’ve already done are so pleasing that I’ll keep them as they are, the next two are for further experimentation.
It’s smooth, the pic is correct, the description is wrong. It’s very slightly deeper than what would be ideal, but the gap remaining between the head and the tube is less than 1 mm, and I’m pretty sure I can find a way to correct that.
Hah! I learned how to get a pic on here. That’s a Skilhunt M150 on the left and a modified SP10 Pro on the right (as per my OP). Both are ‘moonlight-ish’ and about 30 cm from the wall, taken with my phone.
I think I can do even better once my proper 5mm gaskets show up.
Modified SP10 Pro on the left, stock SP 10 Pro on the right.
The difference is considerably more pronounced with the naked eye than the phone pic would indicate.
