Thanks for the tips.
I was interested in his project though because I thought that the price was good. He charges about $140 for the flashlight with the four 3 watt luxs. The Cateye triple shot, which is about 9 watts of leds is around $240 isn't it?

The USE exposure "race" is two 5watt led's That's 10 watts.
So if you look at the picture of the 10 watt led light, you approximate that 12 watts is higher. When you are on that page you can look at the 10 watt halogens, for instance, they should be a little brighter than either LED but it's just an approximation. It puts in the ballpark if you had no idea. Here's a 10 watt total LED light compared to a 10 watt halogen light. Explore the last link on the page and look at all the lights if you're interested. I don't mean that the light he is building is not a nice light, it's great, but not very bright for the price. You could buy something brighter for probably around $80 to $100. There is a lot of nice workmanship in that 4x3 LED he can proud of the finished product, it will last forever.
Look around the forum carefully, I saw a triple shot compared to another light in photos just last night somewhere.
