To round out my day off, I finally made it down the road to check out Pat's new light. It's been a small project of ours to get a bright, yet cheap LED light for commuting once the time changes in a couple of weeks. This is the first go round and it looks pretty good. I didn't get a chance to see it shine after the sun went down, but I think it may work out. It definitely seemed as bright as my 10W Halogen.


The light is about as simple as it gets. It's four Luxeon K2 LED's mounted with lenses to a piece of Aluminum. They're wired in series and connected to 12 AA NiMH batteries that are housed in the water bottle. Running them in series is about as simple as it gets and for now, that's the goal.


The backside looks a bit more complex that it actually is. Being the aerospace engineer that he is, he's doubled the connections coming into the lights. The connections are made with PC jumpers and pins.


And just to speak on the first picture. Pat's big into electric bikes and the wheel covers on the front are hiding a hub motor. So, please, if you see a middle aged dude who's probably not as fit as you and he's taking you to the shed on the trail, think! It's hilarious how many folks have been riding with Pat on the way to work that think he's a freak of nature with incredible acceleration and stamina. He's no freak, just a crafty veteran.
