Thanks,

I didn't intend to steal the dead Kennedy's logo - those are my initials and they machined easily. I guess that it is hard to be original in this day and age.

Try performing a search for Tesla's 1940's "Death Ray" and you will find some interesting info.

And if we want to get totally silly - a small machined pocket for dry ice to be installed for the 'smoke effect' and thermal managment /ubbthreads/images/graemlins/grin.gif

Gorgeous light - I love non-cylindrical lights! /ubbthreads/images/graemlins/thumbsup.gif /ubbthreads/images/graemlins/thumbsup.gif Very high power and run by a Li-Ion battery too?? OUTSTANDING!

(BTW - georges80 - I don't think he'll be seeing too much "smoke" tooling along at 20mph downhill... but for showing off afterward, now... I can see that! /ubbthreads/images/graemlins/wink.gif )

I appreciate the kind remarks.

I will be putting the Death~Ray to the test this weekend in a 24-Hour Mountain Bike Race - North of Tucson - Link to 24 hours of old Pueblo.

I am part a a 5 man team - and will be riding approximately every 4/5 hours around a 16 mile mountain bike course. This is all in a 24 hour period from 12 Saturday to 12 on Sunday.
