How do you troubleshoot a mercury vapor light? Make sure the light fixture is plugged in and the circuit breaker switch is on. Replace any blown fuses at the home’s breaker box. Test the outlet by plugging in different appliance. If the second appliance does not turn on, call an electrician to inspect the home’s wiring.
Why does my mercury vapor light go on and off? Author : Gerald J. If the eye sees light reflected from the pole or a nearby building it will turn the light off, then back on, all night. If the eye sees too much sun set it will be slow to turn on, same thing if it sees too much sunrise it will be quick to turn off.
How long do mercury vapor lights Last? When used with the correct ballast and properly maintained, a mercury vapor lamp has a long service life. The average life expectancy is more than 24,000 hours, or nearly three years of continuous use.
Do mercury vapor bulbs need to be replaced? Due to their low lighting efficiency, mercury vapor lamps should be replaced wherever possible. In areas where identifying colors is important, they should be replaced with metal halide fixtures; if color is not important, they should be replaced with high-pressure sodium fixtures.
How do you troubleshoot a mercury vapor light? – Related Questions
Can you replace a mercury vapor bulb with LED?
LED corn cob lights are one of the most efficient ways to replace metal halide, mercury vapor, and high-pressure sodium HID bulbs.
Why won’t my mercury light come on?
Make sure the light fixture is plugged in and the circuit breaker switch is on. Replace any blown fuses at the home’s breaker box. Test the outlet by plugging in different appliance. If the second appliance does not turn on, call an electrician to inspect the home’s wiring.
How do you test a mercury vapor light?
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.
Do mercury lights use a lot of electricity?
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.
What color is mercury vapor light?
Mercury vapor lamps are gas discharge lamps that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger glass bulb. The advantage is that it produces a bright white light, with relatively long life.
Do mercury vapor lights get hot?
Mercury vapor and halogen lamps are generally used as basking lights. For the most part, they direct heat into a small area. But they get hotter than incandescent basking bulbs.
Is mercury in light bulbs?
Mercury, an essential part of CFLs, allows a bulb to be an efficient light source. On average, CFLs contain about four milligrams of mercury sealed within the glass tubing. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in over 100 CFLs.
Is mercury in LED lights?
LEDs use significantly less energy than even CFLs, and do not contain mercury. A study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances.
What size base is a mercury vapor bulb?
They are medium base (E26), ED17 bulbs with an average life span of 6000 hours. Use in street lights, parking lot fixtures, perimeter lighting, wall packs, and other commercial and industrial lighting applications.
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.
Why does my mercury light stay on all the time?
A light that is flashing typically means the bulb is at the end-of-life. A bulb that stays on continuously is a sign of a defective or worn photo-cell. Be sure that the cell faces North as they do not tolerate direct sunlight. There should be an arrow on the cell that indicates which way to point it.
How do you troubleshoot a high pressure sodium light?
The most common problem with a high pressure sodium light is the bulb. The first course of action is to simply change the bulb. Observe the interior gas tube for any signs of discoloration. If the tube is black, the bulb is definitely burned out.
Why is my Mercury blinking?
This is your indication that it is ready to be connected. If it is not, turn it off and on three more times until it is flashing quickly. Then, select, “Yes, it’s blinking quickly.” You can also reset the light in ap mode.
What causes a high pressure sodium light to go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
What are mercury lamps 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 do you know if a halogen bulb is bad?
The trick is to shake the bulb lightly once the bulb has cooled off completely. If you hear something rattling around, the filament has broken, and you know the bulb has burnt out or is otherwise damaged. Low wattage bulbs may produce a very unpleasant smell if they have burnt out.
How much does leaving a light on all day cost?
A “normal” incandescent bulb costs about 0.75cents per hour, and LEDs or CFLs cost only one-sixth of that – so leaving the lights on (either overnight or while you’re at work for the day, say both are about 8 hours) costs you roughly 6 cents for a normal light and a bit over 1 cent for modern bulbs.
How much does it cost to run a mercury light?
As with most outdoor lighting along streets, the utility company owns and maintains the light fixtures and charges a monthly fee to the town based on the projected electricity use and maintenance cost; Dummerston pays about 44¢ per fixture per day for the 100-watt mercury-vapor lamps and would pay the same for the 50-
Why do sodium lamps take time to glow?
Sodium vapor lights require a brief warm-up period.
Once the arc is ignited it melts and evaporates metal salts (sodium) internal to the device. The light doesn’t arrive at full power until the salts are fully evaporated into plasma (which can sometimes take up to 10 minutes).
What is the principle of functioning of a mercury lamp?
Definition: A lamp that consists of vaporized mercury to generate light by using an electric arc is known as a mercury vapor lamp. Basically, this lamp discharges gas when heated or cooled. The mercury which is present inside the tube is in liquid form (at room temperature) which is ionized before generating light.
How hot does a mercury vapor bulb get?
Re: mercury vapor bulb question
With such high wattage, it will also be very hard to get the cool side temp in the 78 to 82 range which can cause overheating because it doesn’t allow your beardie to be able to thermoregulate.
