    MG P-Rocket w/R5 465* Lumens Available Soon!

    A tiny bit yes. My TK12 R5 has an SMO reflector so it's impressive that the OP P-Rocket out throws it. I'd like to see how the SMO P-Rocket compares. I think it's just the drive level though - my TK12 is only driven at 850ma.

    I see "made in China" everywhere..

    China is hardly a third world country. I'll happily buy products from China after making sure I've done some research into the quality of the company/product - just in the same way I'd do some research into a product that was made in the USA/UK/Europe.
