[Greenbuilding] High Eff LEDs

[Chris Green]

Lunar Accents Design has an article on how to evaluate the cost 
efficiency of LED lights.

This is a fascinating web site with more info about LED's and their 
applications (aircraft landing lights? ) than most of us need to know. 
On the other hand, knowing how many lumens is required for a task helps 
us to not over use lighting or install too many of them.

And it turns out there's an online LED Museum, operated by Craig Johnston.

C. Crane Company has LED light bulbs up to 200 lumens for sale here:
