Well I subscribe to a magazine called "compound semiconductors" and in the latest issue they were discussing LEDs.
It seems that 1000 lumen LEDs (available in various color temps to include the 5000 to 7000 kelvin range) are being made available. No listing of cost but as they are adopted more and more they should become cost competitive when energy savings and replacement costs are considered.
They projected LEDs to have a considerable market penetration in the next 10 years for automotive, business and home lighting.
