I was looking at the Lights in the Forum Store and saw the T20CS from Sunwayman was Available, so I thought I’d post some of the things that make it a great light for anyone that’s looking for a nice light.
I’ve owned one for over 3 years
First the pros
Takes either CR123s or 18650s
Has A low battery warning light
combat grip ring
tail clicky ( cuts parasitic drain and can deliver full power
nice throw and spill balance
quality construction Sunwayman’s fit function and finish are excellent on this light
has the feel of a Surefire U2 and combat light being crossed( personally I bought it because I lost my Surefire U2 that took 18650s)
great priced alternative to a Surefire P1R , U2,P2X

Cons
as a pure emergency light the button on the side is a extra step but if you keep the light in high mode its not a problem. I also like having different levels for battery saving.

not the newest or longest throwing light but still an excellent light .

In conclusion the Pros definitely outweigh the Cons IMO.

Quality 18650 light in a very well made package that I would call a sleeper

If you want a reasonably priced quality light take a look at it. SUNWAYMAN spent some time designing it and it shows
