I was looking for 26650 hosts, and I came across the skyray S2. I like the fact it has a side switch, but I am unsure of the internals.
If anyone has one, can you tell if it has a pill?
I did a search, people have talked about getting them but no reviews yet
I think the group buy on Sky eye/trustfire ( a 26650 light) for $10 is much cheaper and have no pill 
bump.
Sorry - seems it's a pretty rare light. I and couple others have the FandyFire K2 or equivalent and I'm very impressed with it - side switch 26650, very close to this form factor, but I'd say the K2 will be a better quality light.

FastTech seems to have the best price of the major resellers: http://www.fasttech.com/products/0/10005048/1396700-fandyfire-k2-cree-xm-l-u2-5-mode-890-lumen-white-l.
