LED Lights Are More Efficient: They Have Better Lamp and Fixture Efficiency. First, lets take a look at the lamp and fixture efficiency of a metal halide. A brand new 400-watt metal halide bulb has a color temperature of 4000K, a rated life of 20,000 hours, and its initial lumens are 32,000-36,000. While these figures are very impressive, a study carried out by The Dark Sky Society showed that the initial lumen of a 400-watt metal halide lamp are 20,500 and its rated life expectancy is around 15,000 hours. Metal halides are high intensity discharge lamps and all HID lamps are omnidirectional.
LED lights are built differently and produce light that is directional. All the light is focused where it is needed. They Have a Longer Lifespan. The average life expectancy of metal halide lamps is 20,000 hours. However, larger lamps, like 1000-watt metal halides, have a lower life expectancy approximately 15,000 hours.
Since metal halide lamps have a rated life of 20,000 hours, by the time high-quality LED's get to the end of their lifespans, you may have replaced your metal halides 5 times or more. The luminous efficacy of a light source is what determines how much electricity it will save. To get the luminous efficacy, you can divide the total lumen the lamp produces by the total watts it consumes. With this in mind, let us look at the luminous efficacy of a metal halide lamp versus that of a LED lamp. A 400-watt metal halide bulb consumes about 455 watts of electricity.
But metal halides cannot work without ballasts and ballasts also draw a small amount of electricity (approximately 15%). The luminous efficacy of a 400-watt metal halide bulb is: 36,000 lumen divided by 455 watts = 79.12 lumen per watt. This is assuming the metal halide produces 36,000 lumen, which is not the case. A 150-watt retrofit unit generates 23,250 lumen; 23,250 lumen divided by 150 watts = 155 lumen per watt.
Just by looking at the figures, its clear that a LED lamp is more efficient than a metal halide. As we previously pointed out, a 400-watt metal halide lamp produces approximately 20,500 lumen. On the other hand, our 150-watt retrofit unit generates 23,250 lumen But instead of consuming a massive 455 watts, it only uses 150 watts.
If you replace the 400-watt metal halide lamps in your commercial application with these LED units, you will reduce energy consumption by 66% and also provide better illumination in the space. Also, as metal halides get old and lose most of their lumen, their electricity consumption never goes down. As a matter of fact, they consume the same watts they consumed initially and do so up to the end of their lives. When a light expert measures light using a light meter, they get the readings in lumens.Metal halide lamps generate light in all spectrums both visible and invisible. Visible light is the light that can be seen by the human eye while invisible light includes infrared (IR) and ultraviolet (UV) spectrums. LED lamps that are designed for humans do not produce light in IR and UV spectrums, because this light is not useful to humans. This means that a light meter only picks up the visible spectrum of LED light. While a light meter may show that the area illuminated by a metal halide lamp has more foot candles, the reason is because it also measures the invisible light spectrum. Additionally, LED's have better-quality light because they have a higher color rendering index. When you install light sources with a higher color rendering index, you will need fewer fixtures because the quality of the light will be better.
And while the color rendering index of metal halides is much better than that of other traditional light fixtures (such as high pressure sodium lamps), they do not render colors as well as LED's. They Lower Light Maintenance Costs. As we earlier said, metal halide lamps do not have a long lifespan and have a very quick rate of lumen depreciation. They have to be replaced every now and then.When used in large commercial applications, they have to be replaced in groups as changing out single bulbs can be very expensive.
