How Bright is that Light??
Interesting link I saw on another forum. Click the light to see how bright it is.

I started with a Cateye LED light but then upgraded to the Niterider Digital Evolution. Glad I did, those LED lights appear to pin hole lights.

If you look at the Light & Motion and Niterider HID lights, each have identical electronics and HID bulbs, the only difference is the reflector, it makes a LOT of difference.

Excellent link!
I commute through a lot of unlit trails and dark sections of rural and neighborhood bike routes. I ride with a Flamethrower and a Vega as my back up. I use the Flamethrower set to illuminate the distance and Vega set to illuminate just in front of me, or to blink depending upon the portion of my commute.
At 15 feet illuminating a horizontal surface, it might look like the Flamethrower throws a huge bright spot. On the surface of the road, the beam spreads out to give you a nice view of what's ahead. I figured out pretty quickly that the farther ahead that I can see, the faster I can go. That focused beam, more than anything else, has allowed me to safely ride a lot faster in the dark.
I have had several people tell me that they thought that I was a motorcycle on my approach. The cagers definitely give me a wide berth when I have my light and flasher going.

Lighting is not my area of expertise, but I thought I would throw in my two cents on the subject. We all know that incandenscent lighting is inefficient. The power going in produces way too much heat for the amount of light. A good automotive high beam headlamp produces about 1700 lumens from 65 watts, or about 26 L / w, along with a lot of heat. NIR bulbs (Dodge Viper) harness that heat to produce more light, giving something around 2300 L, or about 35 L / w. HID headlamps are better yet, producing more light and less heat, but require a high voltage transformer and other packaging/weight/fragility/cost issues.
There is a lot to be said for the efficiency of LED lighting, but I don't think we are anywhere near the ultimate in construction, packaging or volume cost yet. I receive tons of advertisements from the trade rags claiming all sorts of specially doped 3-5 materials (indium gallium arsenide, etc.) that are capable of full spectrum light up to 60 lumens per watt!! Price for this little wonder? Still high at about $4 in quantity. But they offer incredibly compact form factors making them perfect for really wild designed automotive (and bicycle) headlamp use when clustered.
Lots of good stuff coming down the road....

I like the light frrom the light&motion HID....I just dislike how fugly they look....oh well, can't have it all I guess.
...do those use the water bottle battery, or a jersey-pocket style?
