Great review and convinced me to purchase a SOFIRN 01. Your right on all counts... It is a weapon and you can ditch a weight for diving with it.... But value for money... WOW... Top purchase ... 20years of diving... My best buy
Sofirn wouldn't have tested it in water which would extend runtime. I'm not sure any manufacturer would do this. Kind of misleading. The big thing here is Sofirn most likely tested it with Samsung 30Q's which will hold a higher voltage, meaning longer runtime at the higher levels before low voltage is triggered, or before it steps down
@@vonster22 Yes, but the point of the comment was that this video shows testing in a bucket of water and marking the Sofirn manual's runtime as wrong. The industry standard is ANSI which is 22 +/- 3°C. This guys test method is in error, but a better indication of the runtime while diving
He should put it on a swimming pool at least 5 meters below to test , not in the bucket which affect its temperature it will cooldown if the flashlighr will submerged in a deeper water....
See video description for how to get the Sofirn SD01 light for $71.49

you can use Samsung 18650 35E to add more turbo running time
Did the first turn from the off position to the 350 lumen position feel somewhat loose to you? Cause mine does
Sold me with pistol grip and turbo.
Perfect for hunting garage doors.
How is the beam for signaling buddies ..etc
Very detailed review !!!
Thank you for the great video . I will be buying this torch
Wat sight do I use to order one of those??
What was the maximum depth of operation underwater?
3.30 hours high mode 2000lumen. How long medium mode 900lumen?
Thank you so much this video. 💪💪💪💪💪
Wow! You can find the Titanic or signal nuclear submarines with that thing! 😮
I thing this light is too narrow for video. Do you agree with me?
They make a "pro" version that's better for video.

They test it according to industry standards
