Sofirn SC33

Name: Sofirn SC33
Brand: Sofirn
Price: 40 USD
Availability: InStock

Massive output from a 21700 tube light with Anduril 2. The SC33 is Sofirn's powerhouse — 5,200 lumens and decent throw from a Cree XHP70.3 HI.

Beam profile

Flood, about 32° wide. Wide and even — light where you are, not where you're pointing.

Estimated from 5,200 lm ÷ 22,000 cd — how this works

What owners report

Sofirn SC33/4 sources reviewed

The SC33 pairs a Cree XHP70.3 HI with a 21700 to produce 5,200 lumens with genuine throw behind it, and reviewers rate the emitter choice highly — it's efficient, so the light manages both a lot of output and respectable runtime rather than trading one for the other. Turbo runs about an hour and a half; eco runs for weeks.

It's a big light for an EDC, which is the main complaint: more substantial than most in its class and not comfortably pocketable. The beam has some ringing and the crenellated bezel throws a pentagonal spill — not the cleanest pattern, though it works fine in use. Colour rendering is the usual XHP70 story: cool and low CRI. One thing worth crediting is that no mode uses PWM, so there's no flicker for people sensitive to it.

Consistently praised

XHP70.3 HI is efficient — high output without gutting runtime
5,200 lumens with real throw rather than pure flood
No PWM on any mode, so no flicker
Tail-mounted USB-C charging, full in about three hours
Eco mode runs for hundreds of hours

Common complaints

Big for its class — not comfortably pocketable
Beam shows some ringing, and the crenellated bezel gives a pentagonal spill
Cool colour temperature and low CRI
Turbo is limited to roughly 1.5 hours
Weight follows from the 21700 and the head size

Questions people ask

Is it too big to carry?: For most people, yes, as a daily pocket light — it's noticeably larger than a typical 18650 EDC. It suits a bag, a vehicle or a jacket pocket better than trousers.
What does 'no PWM' mean and why does it matter?: Some lights dim by switching the LED on and off very fast, which some people perceive as flicker and find headache-inducing. The SC33 uses constant current at every level, so there's nothing to perceive.
How is the beam quality?: Serviceable rather than clean. There's visible ringing in the transition from hotspot to spill, and the toothed bezel shapes the spill into a pentagon. It doesn't affect usefulness, but it isn't a premium beam.
Does it charge quickly?: About three hours from flat over the tail USB-C port, which is reasonable for a 21700.
