High Intensity Discharge (HID) lamps and replacing them with energy efficient alternatives
such as linear fluorescent, compact fluorescent, induction lamps or LED lamps.
Proponents of this wholesale shift away from HID claimed low efficiency, poor color,
quick lamp lumen depreciation among the failures of HID. Some of the claims were valid
for fixtures with
magnetic ballasts, also known as core and coil ballasts. Some of the
claims do not take into account deficiencies of fluorescent and LED technologies.
LED (light-emitting diode) light bulbs are an energy and cost-efficient way to light your home. With government regulations halting the production of traditional incandescent light bulbs in recent years, new options have surfaced. The first option created was the compact fluorescent lamp, or CFL. These curly fluorescent bulbs are more energy efficient and last longer than an incandescent, but the bulb contains mercury and takes a while to shine at its brightest.
LED light bulbs are even more efficient to run than CFL bulbs and are just as affordable.
