Has anyone here played with this light at all? I love tube lights, and found this:
I am considering ordering one of them to try out, but if someone has found them to be junk… I will not bother.
They also make it with the XHP50 and SST-20. In it’s basic form, it does not look that impressive, appears to have an aluminum star and I suspect the driver is pretty tame.
Note: it’s CSLNM1 not CSLMN1.
2.8A is very tame. OP reflector is less than ideal for this LED.
Oops, typo that is an odd long name. I am sure the letters all mean something but I have not figured out their naming scheme yet, heck do not even own any of their LEDs yet. My read also indicated that the driver is nothing special, but I am after the form factor, a 21700 tube light that would greatly increase runtimes on a non-hotrod light. I think I am going to order one, just to disassemble and build… you know take one for the team! 
These and MantaRay are just clones of Convoys lights AFAIK, solid design but you can get an S21 from Simon and have a true guarantee of quality IMHO.
