How much power does a mercury vapor light use?

How much power does a mercury vapor light use?

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.

Can I use a lower wattage metal halide bulb?

Quartz vs. Quartz is used in traditional metal halide lamps. Quartz tubes are perfectly acceptable for lower wattage MH bulbs that don’t need to be operated at high temperatures.

Do mercury vapor lamps need a ballast?

A mercury vapor lamp is a type of high intensity discharge (HID) lamp that is typically used for commercial and outdoor lighting. As with fluorescent lights, mercury vapor lamps require a ballast to supply the proper voltage and regulate the current to the electrodes.

Can you put a LED bulb in a mercury vapor fixture?

If you use the lights for indoor or outdoor replacement, LED light, overs the halogen and sodium bulbs, is much water-proof and thus the durability is greatly improved. Most importantly, you can save much electricity cost if you use LED lamps to retrofit mercury 400 watt vapor lamps, 175 W halogen lamps!

Why is the 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.

What color is mercury vapor light?

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.

Are metal halide lights energy efficient?

Metal Halide lights have average efficiency (75-100 lumens/watt source efficiency). They lose out to LEDs principally because their system efficiency is much lower (<30 lumens/watt) due to all of the losses associated with omnidirectional light output and the need to redirect it to a desired area.

Is there a difference in metal halide bulbs?

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.

How do you dispose of mercury vapor lights?

If your state or local environmental regulatory agency permits you to put used or broken CFLs in the regular household trash, seal the bulb in a plastic bag and put it into the outside trash for the next normal trash collection.

How do you test a mercury vapor ballast?

You should now test the mercury-vapor lamp. Plug it into an outlet and take measurements of the voltage that goes between the capacitor lead that is black and the COM. This will tell you whether the lamp and the capacitor are good. The voltage should read 15 VAC, but it should ramp up to 130VAC within 5 to 10 minutes.

Can I put an LED bulb in a sodium fixture?

High pressure sodium bulbs (“lamps”) are an old standby for lighting that’s still used today in spite of so much talk of LED lights. LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.

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.

Where do you use mercury vapor light bulbs?

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.

What are the risks of mercury vapor lamps?

Risks/Benefits. Under normal operating conditions mercury vapor lamps provide efficient, long-lasting sources of light. However, if the outer bulb breaks, and the inner tube continues to produce unshielded light, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, blurred or double vision, headaches,…

What’s the difference between led and mercury vapor?

Both mercury vapor lamps and LEDs come in a wide array of colors, sizes, and shapes. However, mercury vapor lamps can become limited as they age. Although the most common mercury vapor lamps start out as a bright white light, they typically develop a blue-green tint over time that can affect visibility.
