How fast do the lumens decrease in an incandescent bulb?

Very quickly, less than 1/10 second. Incandescent bulbs produce only about 10 lumens per watt of power, with the halogen type producing abiut 1 lumens/watt. Low-energy bulbs and LEDs produce about 50-60 lumens per watt.


Why are LED light bulbs good?

LEDs use the smallest amount of electrical power to produce a given amount of light. Approximate data: Incandescent 12 lumens per watt Halogen: 15-17 lumens per watt CFL: 50 lumens per watt LED: 80 lumens per watt Sodium lights as used in street lighting produce 100-200 lumens per watt.
