I can confirm that the stock SP70 reflector is indeed lightly OP as stated by Sofirn. The L6 OP reflector is noticeably more bumpy. It can be really hard to tell from a picture, but I think I captured it in this photo.
I also noticed that the SMO reflector was 71mm across its inner diameter while the lightly OP is 74mm 75mm across its inner diameter. So the SMO is slightly smaller than necessary.
Using the Sofirn HD 25A cells I found the candela very similar between these two reflectors.
SMO - 192kcd - 876 meters
Light OP - 188kcd - 867 meters
Maybe there is room for improvement in the SMO by making it 74mm and maybe change the height or parabolic shape. I got the same purple dot in the center of the hotspot. I haven’t had time to play with reflector height, yet.
Between these two specific reflectors, Sofirn definitely made the right choice. The lightly OP beam looks great and is still pretty tightly focused. At a distance, the hot spot looks the same as my SMO L6.
The most distance I’ve got out of my L6 with SMO and 19 amps is 830 meters, the SP70 with OP and only 12.3 amps is already beating it.
Here are the new HD 25A battery labels. I wish they looked more different compared to the older 26650 black cells. Maybe a different color.
They performed almost as good as my black Liitokala 5000mah. The Aspire 4300 still has the highest amps. I tested them in my L6 at 5 seconds and at 30 seconds.
Black Liitokala - 16.8A, 16.1A
Aspire 4300 - 19.1A, 18.2A
Sofirn HD 25A - 15.5A, 14.5
So not bad. I still need to do capacity tests.
In testing the current in the SP70 I used Black Liitokala 5000, Aspire 4300 and the Sofirn HD 25A.
I measured at 5 seconds and 30 seconds with a short led cool down in between.
Liitokala - 11.9A, 11.5A
Aspire - 13.0A, 11.5A
Sofirn - 12.3A, 10.8A
So it’s not pulling the big amps like my Lexel built FET driven L6, but it’s still a lot.
I can also see the amps start to steadily decline as the temperatures get hotter. That 10.8 reading would probably be a little higher if the light weren’t so hot due to previous tests.
