Back from my morning ride, with report.

Here is the light I bought. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Good: Small. Pretty bright for it's size. Everything is self contained. It seems to have more of a spotlight in the middle, that looks to be about 10' wide when positioned about 25' ahead of the bike. Then there is another area of light, less bright, that spreads across the width of the road. More like a flood light.

Bad: Maybe not bad, but I would like it to be brighter.

I don't regret buying it. The tailight is very bright. I would like the headlight to be about twice as bright.

This is really where the issues come into play, for myself. Several of the lights I looked at, needed a battery pack. That's just something else to strap to the bike. You get stuck between more lumens vs. how to get power to those lumens vs. runtime.

I won't buy this one again. I'll keep looking for that Holy Grail of lights. Super small, but bright as daytime, and lasts a long time on a super small rechargeable battery. And of course, not too expensive.
