I saw Jake Dyson's new task lights at Design Junction in London this past week and they are amazing - expensive - but amazing. It moves more freely than any task light I've ever seen and puts out a good warm glow with LED's that will last forever. My fave is the red and silver that will be in stock soon.
"The CSYS Task is a dimmable LED task light which marries the latest technology with sleek design. It is designed with innovative positioning, refined thermal management and electronics systems producing a bright warm white colour with astonishing efficiency. The thermal management heat pipe technology cools the LED’s to ensure peak performance from the LED’s for 37+ years."
