Wherever the need for bright, voluminous light exists, you will probably find Metal Halide (MH) lamps, or High-Pressure  Sodium (HPS) lamps, commonly known as High Intensity Discharge (HID) lamps, providing this type of illumination.  Parking lots, large retail stores, manufacturing plants, sports arenas, and residential landscapes all rely on HID lamps to keep areas well-lit and safe for individuals to navigate.

High-intensity discharge lamps, or HID lamps, were popular 20 to 40 years ago. Metal halide lamps are one of the most popular types of HID lamps. They were popular for commercial uses outdoors because of the white color of their lighting, as opposed to a different type of HID lamp like high-pressure sodium, which emits a yellowish light.


Recently, businesses have sought to replace HID lighting with LED or light-emitting diode lighting. LED lighting is more energy-efficient and environmentally friendly than HID lighting and generates less heat. For many of these businesses, this switch to LED lighting means a metal halide led retrofit.

Problems with metal halide lamps have led to widespread replacement of these lamps with LED replacement bulbs. Some major issues with metal halide lamps is their quick decay in brightness and an end of life condition called cycling. When Metal Halide lamps start to die, the gas pressure inside arc tubes increases. This causes the lamp to heat up considerably and use more energy to maintain illumination. In some cases, when Metal Halide lamps exhibit signs of cycling, they could explode as the lamp’s voltage exceeds the amount of voltage afforded by the ballast.

High-pressure sodium (HPS) lamp bulbs are also being rapidly replaced by LED replacement bulbs that do not emit monochromatic yellow illumination and restrict vision capabilities at night. In addition to going through the cycling process at the end of its life, HPS lamps have low color rendering – the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. LED replacement bulbs are able to mimic the same color temperature of HPS lamps but with high color rendering

Why Replace 100W to 400W Metal Halide Lamp Bulbs with 20W to 120W LED Replacements?

LED Lights Emit Omni-Directional or Directional Light

Although LED lights have some amount of lumen depreciation, it is not nearly as rapid a depreciation as Metal Halide lamps. In fact, LED light bulbs have a rating of L70, indicating LEDs retain at least 70 percent of their initial brightness after 50,000 hours compared to Metal Halide lamps decaying to 70 percent of their initial brightness in just 6,000 to 10,000 hours.

120W LED Replacement Offers Extended Life Expectancy

Most Metal Halide lamps burn for about two years. Larger Metal Halide lamps burn less than two years, especially 1,000W or 1,500W Metal Halide lamps. Top-quality LED lamps with L70 ratings can be expected to last five times as long as Metal Halide bulbs.

Reduces Energy Costs with Better Luminous Efficacy

A 400W Metal Halide lamp would consume approximately 450 Watts of electricity including the ballasts which they need to operate because ballasts are essential components of Metal Halide lamps consuming an extra 15 percent of the energy required to illuminate a Metal Halide Lamp. Alternately, a 120W LED replacement for a 400W Metal Halide lamps can cut energy usage by over two-thirds and save users hundreds of dollars in energy costs.

Reduces Maintenance Costs

With shorter lifespans and rapid lumen depreciation rates, Metal Halide lamps require more maintenance than LED lamps. When large industrial or commercial operations change metal halide bulbs, they often wait until multiple lamps have burned out to defray maintenance expenditures. Depending on the type of operation relying on Metal Halide lamps, lack of illumination can create safety concerns and potentially lead to loss of customers. 20W to 120W LED replacement lamps outlive Metal Halide lamps by a factor of 2-4 times, and do not need replacing nearly as much as Metal Halides do while providing improved illumination.

How difficult is a metal halide retrofit?


A metal halide retrofit doesn’t have to be complicated. At Olympia Lighting, we have designed our LED lamps to fit perfectly in old HID fixtures, including enclosed fixtures, which are often tricky for LED lamps. Metal halide lamps contain mercury and generate a lot of heat at high power. This heat sometimes results in dangerous explosions or breakage, so many of the higher-power metal halide lamps were placed in enclosed fixtures for safety. LED lights generate less heat, but they also have electronics inside, so heat management is critical when they are enclosed. We’ve designed all our lamps to withstand the heat of enclosed fixtures for at least 50,000 hours.


Retrofitting also doesn’t have to be expensive. Many of our LED replacement lamps are SEC qualified, which means that customers nationwide can receive a rebate from municipalities or local utilities. A customer recently received a rebate for replacing the lights in the parking garage that equaled the cost of the lamps. Since the LED lamps save energy, customers save money on their utility bills after installation.


How efficient are the LED replacements?


Our LED replacement lamps provide efficient light, about 165 lumens per watt. A 100-watt lamp will provide 16.000 lumens and the equivalent of a 400-watt metal halide lamp. A 1000w metal halide led replacement requires only a 250w LED lamp. Our product line goes to 300 watts, which is the equivalent of a 1200- watt metal halide lamp.


The LED replacement lamps also provide excellent color visibility. The Color Rendering Index is 75.


Are LED lights highly susceptible to electric surges?


Electric surges can significantly shorten the life of LED lights. The surges can cause components to overheat and melt, leading to short circuits. We have developed a surge protection device that we insert into our LED lamps to prevent this damage. This patent-pending device is unique to our company and our products. Because of this product and other aspects of our design, we are confident that our lamps will last beyond their five-year, 50,000-hour warranty.
