The age of incandescent bulbs and fluorescent tubes is over. LEDs have proven their value economically and visually, and are being developed for every imaginable application. Nextek is at the center of this revolution, providing the most efficient way to power and control LED lamps. Left, below, is a traditional fluorescent tube. These have short lifespans and low power efficiency. Left, above, is an example of an LED alternative—a fluorescent-shaped tube with embedded LEDs. These have significantly longer lifespans and are incredibly more efficient than fluorescents.
