    Actually no. I have the k21 I just got in for review, same as what you linked I gather, just different case design. little less output and cool white emitters vs bt21. Nice quality lights though, Im reviewing it and the USB chargeable one right now. But After getting into the K21:

    Cool white emitters vs bt21 Nuetral white
    Better helmet optics vs bt21 frosted optics, liked beam better than bt21
    heavier than bt21 by 40g
    runs alot cooler than bt21 due to increased case size and lower max output
    finish quality is a bit better (no light leaks around front, good waterproofing)

    So good lights, just lacking a little on output and a bit heavy for dual emitter lights. But Im also guessing the K20 is a bit lighter since case is noticeably smaller. THere is another thread about that light too (people paid 3x that for the light, which wasnt worth that much IMO) and those couple people were very pleased with it.
