Why does my mercury light bulb go on and off?
As a lamp gets older, the maintaining voltage for the arc eventually rises to exceed the maximum voltage output by the electrical ballast. As the lamp heats to this point, the arc fails, and the lamp goes out.
Why do my light bulbs keep going out?
The most dangerous reason why your light bulbs keep burning out is that the voltage in your home is too high. If you notice multiple light bulbs in different rooms of your home are burning out frequently or at similar times, that could be a sign that your home’s voltage is too high for your electrical wiring to handle.
How long does a mercury light 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.
Can mercury in light bulbs hurt you?
When the tube of a fluorescent light bulb breaks, the mercury vapour inside is released into the air. Most of the mercury released from the CFL turns liquid very quickly so, shortly after the breakage, the level of mercury vapour becomes too low to cause any harm to adults, even those who are particularly sensitive.
How do I convert my mercury vapor light to LED?
The quick way to retrofit or replace your 400 watt mercury vapor bulbs is to consider the power selection. For instance, a 400W mercury vapor emits 400 * 40 = 16,000 lumen. Therefore, we need 16000 / 140 = 114.3W LED lights to do the replacement.
Why do LED lights burn out?
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
Why do LED lights burn out so quickly?
The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!
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.
What should I do if I break a mercury light bulb?
Remove children and pets from the room, and then clean up the broken bulb as quickly as possible. First, increase the ventilation in the room where the bulb broke by opening windows and doors. Then use index cards or other stiff paper to pick up the broken pieces of glass and any visible mercury.
When do mercury vapor light bulbs shut off?
There are two types of mercury vapor light bulbs sold in the U.S. âTâ type light bulbs have a self-extinguishing feature that shuts off the light within 15 minutes after the outer bulb is broken.
What happens if you use a mercury lamp?
Using a mercury vapor lamp with a ballast that was made for a higher wattage bulb might damage it or cause it to explode. Using too small of a ballast will result in lower light output and can shorten the life of the bulb. There are two types of mercury vapor light bulbs sold in the U.S.
How does a mercury vapor light fixture work?
It was the original metal vapor style of light fixture to be mass produced for general purpose lighting. The mercury vapor lamp works by creating an electric current to mercury vapor within a sealed glass jacket. The bulb is comprised of an inner tube, called the arc tube, and an outer jacket (or bulb).
Is the sale of mercury light bulbs still legal?
Although the bulbs are still widely available, the United States banned the sale of mercury vapor ballasts in 2008. According to the ban, existing fixtures can remain in service but, as they burn out, they must be replaced with newer, more efficient lighting alternatives.
