Hello All,
I got into LEDs to light up the night while riding my recumbent to work (you are not alone, Mark) I have the same flasher that Velcro uses in his picture and wanted a nasty one for the front. This lead me down the slippery slope to the CPF. /ubbthreads/images/graemlins/ohgeez.gif /ubbthreads/images/graemlins/thumbsup.gif
At this point, I use a Badboy 400 Q3L Brinkmann with NX05 optics mounted on my helmet (to look at drivers to let them know I am there) The frame mount is a little more insane. A 5D Mag with the 5 watt Cyan (blue-green) Luxeon fitted with Elektrolumens 30mm pencil beam optic. It has a very long throw and is blinding if you look directly at it. Cyan is very noticable to the human eye and approximates a 10 watt halogen.
I have a regulator and will mod it with Elektrolumens "3toD" adaptors (3 AA batteries in a D cell) Eventually, it will be much lighter with regulated brightness once I get off my butt and really care!
Elektrolumens makes a 1.2 watt Luxeon headlamp that uses the piercing 30mm optics. It runs on 4 AA cells and you can mount it to your helmet by using a velcro strap to mount it through the slits.
If you want regulation, wayne also sells a thing called a micropuck that can be wired in. It might require rewiring the 4AA pack to run the pack at 3 volts instead of 6 but that would double your battery life. (or you could just put in two cells to make it lighter) The micropuck is a regulator that will give you even output. The headlamp is $30 with the micropuck adding another $14 to the price.
I am thinking of doing that mod myself, a headlamp that is piercing, lasts a long time on batteries and uses regulation is too good to pass up.
Here is the link to the Luxeon headlamp.
