How many lumens is a 400 watt mercury vapor bulb?

22000 lumen
These 400 watt Mercury Vapor bulbs have a bright 22000 lumen output. They are mogul base (E39), ED37 bulbs with an average life span of 12000 hours. Use in street lights, parking lot fixtures, perimeter lighting, wall packs, and other commercial and industrial lighting applications.

What is a mercury vapor bulb used for?

Description. Mercury vapor lamps are bright, long-lasting light sources that are often used to light large areas such as streets, gyms, sports arenas, banks, or stores. The bulbs have an inner quartz tube containing the mercury vapor discharge.

How many lumens is a mercury vapor light?

Mercury vapor lamps are more energy efficient than incandescent and most fluorescent lights, with luminous efficacies of 35 to 65 lumens/watt. Their other advantages are a long bulb lifetime in the range of 24,000 hours and a high intensity, clear white light output.

Do mercury lights use a lot of electricity?

Is mercury vapor Harmful?

The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.

Why is mercury Vapour at low pressure?

Fluorescent and compact fluorescent lamps work based on the low pressure gas discharge principle. The glass tube on low pressure gas discharge lamps is filled with a noble gas at low pressure and a small quantity of mercury. The discharge process causes the mercury vapor to emit UV rays.

Do mercury vapor lights use a lot of electricity?

Compared with newer HID lighting, mercury vapor isn’t very energy efficient. The “efficacy”—or amount of light produced per unit of electricity consumed—is 20-60 lumens per watt. This is better than incandescent lamps (about 15-20 lumens per watt), but significantly lower than other HID lighting.

What is the Colour of mercury Vapour lamp?

Sodium vapor and mercury vapor lamps emit yellow and bright blue light, respectively. They are very efficient, and provide high-intensity light suitable for illuminating large, open areas.

Which is better HPS or mercury vapor lamp?

Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level.

How long does a clear mercury lamp last?

The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. Assorted wattages and bulb types available to choose from. Life = +24,000 hours. CRI = Clear 20, Deluxe White 45.

What is the wattage of a CRI light bulb?
