What owners report

Sofirn SP36 Pro/5 sources reviewed

A soda-can-format triple running on three 18650s, and one of the most consistently recommended high-output budget lights. Around $50 buys 8,000 lumens, three 3,000mAh cells in the box, aerospace-grade aluminium and Anduril 2 — reviewers describe it as a lot of torch for the money, with a balanced beam rather than pure flood.

The criticisms are mostly ergonomic. There are no anti-roll flats anywhere, so it rolls off anything with a slope. The cooling fin edges are mildly sharp. Charging three cells takes a long time. And the SST-40's tint is cool and sits above the black-body line — a greenish cast with low CRI — which is the price of the output. The same thermal-sensor calibration quirk as other Sofirns of this era can make it step down early; there are published fixes.

Consistently praised

8,000 lumens with three 18650 cells included, for around $50
Anduril 2 with all the configurability that brings
Balanced beam profile rather than pure flood
Good size and weight for the output rating
Build quality reviewers call perfectly acceptable, and better than the price suggests

Common complaints

No anti-roll flats — it rolls off any sloped surface
Cool, greenish SST-40 tint with low CRI
Charging three cells takes a long time
Cooling fin edges are mildly sharp
The thermal sensor can need recalibrating or it steps down early

Questions people ask

Why does it step down when it isn't hot?: A miscalibrated thermal sensor, common on this Sofirn generation. Anduril lets you recalibrate the temperature reading and raise the ceiling; guides for the procedure are widely published.
Does it come with batteries?: Yes — three 3,000mAh 18650s, which is a large part of why the value looks so strong. They should be kept together as a matched set.
How is the tint?: Cool and slightly green, with low CRI. This is the standard SST-40 compromise: it's what allows the output figure. If colour matters more than lumens, this isn't the light.
Is it pocketable?: No. It's a soda-can light — a bag, vehicle or camp light. It's compact for its class, not for carrying.
