Default 23 W, 17000 CBCP light for my experimental bike

Hello, alt.mountain-bike readers.

I have read about the superior Lupine Edison series of lights.

I have been working on an experimental bicycle aiming for a
battery-free night century ride. My current setup is Lightning
Thunderbolt recument and an EV Wilderness 600 W, 36 V brushed, gearless
front hub motor/generator with six Maxwell Technologies PC 2500 2700
farad ultracapacitors rated 2.5VDC and a Samlex sine wave inverter
rated 150 W.

I have a compact fluorescent light on a bit of track under the boom but
it's not wired yet.

I have researched GE's new Ceramic Metal Halide lights and find the PAR
30, 20W light just might be suitable for mountain biking or a night
century. There is a track lighting fixture available to take this 20W
bulb or a mini 20W bulb. All the CMH bulbs produce some of the best
lumens per watt, but the key to road use seems to be Center Beam Candle
Power, CBCP. This fixture is rated 17,000 plus CBCP. It's used for
spotlighting merchandise in upscale retail stores, and in homes as an
accent light.

The mini 20W fixture with integrated electronic ballast from Aromat
consumes 23 W and the inverter idles at 6W. A 25W inverter would idle
at only 2W. Bearing drag on the hub is around 3W at 8 mph.
Motor/generator efficiency is lower than I had thought; there are many
ways to test it, and all take physics lab work, which I don't have
access to, so I just coast down local hills and see how the charge on
the ultracapacitors comes out.

I am going for a ride now; it's almost dawn.

I think soon I will be ready for my night century.

Just thought I would drop by and ask if there are any riders in the DC
area who would like to try a night century. Maybe a metric century to
start.

Also, do any of you know CBCP ratings for any MTB lighting system?

Sorry, we're not really overnight bent century geeks here. There are a
few 24 hour freaks here but they ride real bicycles.

Yeah. That diamond frame over-the-shoulder thing can't be beat,
especially with a nice light bike. My next energy bike, using smaller
caps, will be shoulder-carry. Sure does give you some options on where
to live. Schmoopie and I fight over where to park the damn thing and
how to keep a path clear.

Is that an article (post) you wrote in rec.bicycles.recumbent titled
"How to Get a 'Bent Upstairs", or something like that? I really must
look that up.

I think I found cc's post in arbr. Made me laugh.

Get wedgified! Haha. Not bad advice, though. Sure is funny how the MTB
diamond frame allows use in rough terrain. Not many MTRs.
