IMHO LEDS are the next best thing to sliced bread! Some of those new style traffic lights also employ the white LED strobes in them to get motorist attention from a distance. They are effective too. The LEDs are wide dispersion and often not hindered by intense sunlight as compared to the older incandescent types. Hooray for hi-tech LEDs!!
Love that lamp, will probably cost far too much though. The LEDs have got to use far more power than an incandescent equivalent and are small enough to be styled in this way.
EDIT, seems I found the price, and at over £700 it seems a little excessive...
700 pounds ?! Good lord, this is far too expensive.
I think a hyperluminescent OLED panel of the next generation will do the same job, but ways better.
