Re: My bent dual cree
Thing on folk is cateye el530, with upgraded led. Very good backup light.
Well, I found the bent design lighted up the whole road nicely, which isn't so good really. I don't really care whats in the other lane and the grass on the verge is pretty boring too.
I straightened things out.
I also wanted to get things off the bars for the handlebar bag mounting. Almost went for the folk braze ons but need to keep them clear for front rack.
One side on copper pipe bashed flat. Not very straight holes drilled opposite. Oops. Last bit of pipe so will be ok.
Copper bracket bent up so fits under cables and on top of mudguard and brazed on (getting the brazing done cost me a beer). Overcoated with clear to keep it looking shiny.
Two Q5 cree XR-E leds and cree optics stuck on to flat portion of pipe. Mylar over holes.
Epoxy and yellow food colouring seal the ends to create side lights (will go carbon fiber next light, quad cree for the MTB, very very soon).
Driven by taskled bflex (awesome driver) and 12AAs. Did 4 hours on not full batteries, expect about 5 now, have turned it down to 750mA max as not much difference betweeen 700 and 1000 visually but sucks through batteries. Bflex controller mounted in box on stem, one button control over 3 brightness levels, constant or strobe mode, and low battery led.
Black line in beamshot is mudguard, now cut shorter, as in photos. Just a tiny black stripe where the shadows of the tyre overlap. Should of mounted the leds a few mm apart!
Its a nice tight beam and great for the road.
Beam at 1A
1A gives lots and lots of light!
