Bicycle lighting

See also the Wikipedia Bicycle lighting article. It includes links to some interesting LED based homemade systems.

• SolidLights
Based in Cambridge. I had a chance to try one, and it was very nice (but expensive). I wrote a review comparing them with my existing systems. The "new" twin LED dynamo version mentioned at the end of that now has an updated version available as an upgrade, but not yet listed as a whole new unit.
• Busch & Müller Lumotec dynamo lights and others
I now have an IQ Cyo
• SON Edelux uses the same optics as the B&M IQ, but different electronics and better heatsinking gets more power out of it. At a price, but probably state of the art, light the SON hub.
• Exposure (USE), and some measurements on them. Advertised as 5W LEDs, but they aren't running them at 5W (or at constant power).
• Lumicycle Neat little MR11 halogens, now with halide and LED options too.
• Fireball (More expensive than Lumicycle, but maybe nicer (bayonet lock on cable, for example) (SolidLights use the same bayonet connector))
• Cateye (Little LED lights up to HID)
• Lupine - awesome specs, awesome prices.
• Light and Motion
• Laseredge (Look a bit like a US Lumicycle)
• Vistalite
• Niterider
• Night-Sun
• Nite Hawk
• Nova

• Willie Hunt's Lightbulb Voltage Regulators (as used by Surefire's very nice very expensive flashlights).
• Regulator for hub dynamo
• Don Klipstein's Lighting Info Site (including high efficiency LEDs).
• Lots about dynamos, in German
