Compact Fluorescent Lamps (CFLs) were the first generation of energy-saving bulbs. They are a good alternative for wasteful incandescent bulbs, however, they do take some time to warm up, and they can often seem quite dim until they get to their full light output. LED lights, on the other hand, reach their full light output instantly. LEDs are also even more energy-efficient than CFL bulbs, they can be recycled, and they have a much longer lifespan.
