NISKAYUNA, N.Y.--General Electric yesterday held a symposium on lighting at its Global Research center here, where it introduced a prototype of a very bright LED, shown here. The LED downlight uses an active cooling system that allows it to put out 1,500 lumens. That's the same as a 100-watt halogen, but it uses one-third of the energy. The active cooling system means that this light takes up about half the space as a 600-lumen downlight.
