As the metal halide lamp ages and is constantly being turned on and off each day from regular use, it begins to lose its ability to hold an internal gaseous glow, until eventually completely failing to provide the correct spectrum of light, or completely burning out. Aging LED's do not exude these similar characteristics. An LED aquarium light fixture designed to replace metal halides, can provide up to 100,000 hours or more, making LED lighting a more practical choice.
