The convenience of having the light part of the protection system seems terrific and that's why I purchased it. Having to deal with another separate light did not appeal to me. I was hoping to get the K3 before my two week car camping trip but it was back-ordered. I used my camping headlamp but for books, not the k3. Some engineering type should be able to measure the draw by the lamp but I've seen no specs on it. It is 3 led bulbs.
I'm not sure if it could have been designed to pop out of the top middle for more even light but it works quite well other than not illuminating the keyboard, at least, that's my impression.
