I've never tried them or heard any reviews from anyone who has, but from everything I have read/heard about the 2stroke in general, they are complete trash. If I remember correctly, they actually put out less lux than the halogen bulbs in the test they ran on headlight revolution.
I would vote for the Katana LED, or if you want to spend more money (though I still havent seen any reviews of them) VLED has a Micro Extreme that you can get in 5000k or 6000k, which would both be better than the typical 6500k of most LED bulbs. If you go that route, I suggest getting their 6000k. I bought some 5000k fog light bulbs from them, and they look to be closer to 4300k.
