Sofirn recently asked me to review the SF-25A on Amazon.
There are several stand-alone reviews of the SF-25A here, so I decided to do a comparison instead.I will be comparing all of my multi-emitter lights.
Left to right: BLF LT-1 (Sofirn), BLF Q8 (Thorfire), Manker MK-36, Emisar D4S, Sofirn SF-25A, Lumintop FW3A (copper), Fireflies PL47.
I won the MK-36 in a BLF contest. Sofirn provided the SF-25A for the Amazon review. I paid for the rest.
Build Quality
I cleaned and lubricated the threads with silicon grease before ranking them.
Finish
User Interface
Aux Lights
The quad emitter lights have either aux lights, a lighted switch or both.
Ergonomics
The switch is often overlooked. My ranking
Hand Holding.
The D4s wins this highly subjective category. It fits my hand well and the fine knurling works well and feels great.
I also like the MK-36. Three 18650s allow for flats on the body that work.
