The Sofirn SP33 looks like a seriously tactical flashlight, and first impressions were really good.
I picked up the Sofirn SP33 on Amazon. It was not very expensive, it is bigger than I expected, and the box even has a German slogan about making the night as bright as day. It runs on an 18650 battery and has a single side button. The SP33 has been replaced, so the button below goes to Sofirn’s current model in the same series.
- Robust aluminum build that still feels light
- Bright, clean white beam without a yellow tint
- Simple one-button control with several levels
- Two lanyard holes
- Long press to turn on takes a moment to learn
- Big for pocket carry

Build quality
It is a serious-looking light. You get a flat lens in an aluminum bezel, a twisting head, flat edges and fins, and a side power button that seems to have a small LED in it.
The body has really aggressive knurling, like a baton, and the tail is milled as one piece with two cutouts for the lanyard, so it does not stick out the bottom.

Modes
A long press turns it on and off. A tap steps through the brightness levels, five in my count, then back to low. A triple click gives strobe, and it is a fast one that alternates speeds.

Beam
Outside, the beam is a bright white without that yellowish look, plenty to scan the yard.

About the buy link
The SP33 I reviewed is no longer sold, so the button goes to the Sofirn SC33, the current model in that series. Specs differ, so check the listing.
Verdict
Fantastic flashlight: very robust, surprisingly light, and simple to use.
