Ok, I realized that my light has a more efficient reflector and apparently, light & motion uses custom halogen bulbs that get 30 lumens/watt. Which means that the 16 watt beam that I normally run gets about 480 lumens, and the 11 watt beam gets 330 lumens, which explains why it gets almost as much light as a HID. And on both beams, I'm running around 800 lumens.
Anyway I updated the chart with slightly more reasonable speeds and added a few things.
