Here is his review:
Here is information on the Dynamo I ordered.
Dynamo: SON28, Polished, 36 hole, Part Number SCH303601: $ 282.00
It is also available in a 32 hole version.
I also purchased:
Headlight: Luxos U, Part # B&M179U-04LSR, 54cm length wire to handlebar switch/USB port: $ 258.00
Taillight: Toplight Line Plus BrakeTec with pulse, Part # B&M323ALTV-A: $ 57.00
Schmidt Co-Axial 55cm wire to connect Luxos to SON dynamo hub, part # SCH55CM48-3: $ 10.00
Schmidt Co-Axial 190cm wire to connect Luxos to taillight, connectors at both ends, part # SCH72080: $ 12.00
The headlight is very bright headlight and has a wide flooding beam. The taillight is large and has braking indication; it also doubles as a reflector. I feel very comfortable riding at night and other limited visibility situations using this combination. It is all LED so there is very little drag when everything is turned on. I leave them on all the time; even on bright sunny days so I people can still see me when I ride into the shadows of roadside trees.
I also feel more comfortable with the co-axial wiring then I do with the two wire cables.
The dynamo will keep my Garmin Touring Plus charged but it can't keep up with the drain of a smart phone. I found you need a battery between your Garmin and/or smartphone so you keep external power applied when going slowly up a steep hill. If you don't use the battery, the devices detect the loss of external power and start sounding alarms which uses precious power.
I purchased my battery from Radio Shack (1000Ah). It has both a 1 A port that is sufficient for the Garmin and a 2.1A port need to charge my smart phone. The 10000Ah capacity allows me to charge both my Garmin and my smart phone overnight with power to spare. This is very helpful if I am camping and don't have AC access. I can charge the battery while riding the next day.
I am very pleased with my lighting system. I have it on my touring bicycle which I use for heavy touring, light touring on groomed trails, and for winter commuting when the roads are sloppy and I am riding in the dark quite often. (I use my road bike with a simple battery powered headlight and taillight combo in the summer when the roads are cleaner and when there are many daylight hours.) #Dynamo #BikeLighting
