A. no power to the fixture that won't turn on. B bad electrical connection. c. burned out fluorescent lamps d. bad lamp holders e. bad ballast f. etc.
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
It depends on the lights you use. You want the light to slightly overlap the other lamps.
street lights are connected in parallel mostly because if any lamp stops glowing but the other lamps continue their glow
The advantages of parallel arrangement decorative lights are:More brightnessWhen one light bulb blows out, the other ones do notLast much longer than series lights
A loose or disconnected neutral wire at breaker box or at the appliance. Depending on what is on when and if two or more motors are running at the same time. This can as well have the opposite effect too, lights too bright.Although loose connection can cause a problem and you should have all the connections checked, it could also be caused by several other reasons. You distance from and the load on the transformer, the size of you service conductors or lateral, the age and maintenance of your appliances. I have found out that light dimming happens in almost every house but some people are more sensitive to it than others.Usually dimming of lights when an appliance kicks it is caused by a voltage drop of the supply caused by a heavy demand for current when the appliance initially starts. This is usually associated with an appliance that has a motor such as a refrigerator, furnace, washing machine, vacuum cleaner etc. Motors demand about 6 times their steady running current when they first start up and this can be a significant surge of current for maybe a half second or so till the motor has started and is up to speed. This basically momentarily 'overloads' the supply and lowers the voltage available to other devices, thereby causing them to momentarily slow down (if a motor) or dim (if it is a lamp).If you switch to the new power saving compact spiral bulbs, their internal electronic ballast compensates somewhat for line voltage, so they won't react as noticeably to heavy loads starting up elsewhere in your house. The same is true for fluorescent tube fixtures with electronic ballasts.One more point:If the lights are on a dimmer, they are very sensitive to change in voltage and will change their brightness disproportionately to the slight changes in voltage caused by motors or other heavier loads switching off and on.
T8 fluorescent lights fixtures are energy-efficient, long-lasting, and provide a bright, even light. They are cost-effective and environmentally friendly compared to other types of lighting options.
Round fluorescent lights are energy-efficient, long-lasting, and provide even illumination. They are also cost-effective and environmentally friendly compared to other types of lighting fixtures.
T8 fluorescent light fixtures are more energy-efficient, have a longer lifespan, and provide better quality light compared to other types of lighting fixtures.
T12 fluorescent fixtures are energy-efficient, provide bright light, and have a long lifespan. Compared to other lighting fixtures, T12 fixtures are cost-effective and environmentally friendly.
Fluorescent tube light fixtures are more energy-efficient and have a longer lifespan compared to other types of lighting fixtures. They also provide a brighter and more even light distribution, making them ideal for larger spaces. Additionally, fluorescent lights produce less heat, reducing the risk of fire hazards and making them a safer option for indoor use.
T8 fluorescent light fixtures are more energy-efficient, have a longer lifespan, and provide better quality light compared to other types of lighting fixtures.
Long fluorescent lights have several benefits compared to other types of lighting fixtures. They are energy-efficient, provide bright and even lighting, have a long lifespan, and are cost-effective in the long run. Additionally, they are environmentally friendly as they contain less harmful chemicals than other types of lighting.

A 2 lamp fluorescent fixture is energy-efficient, provides bright light, and has a longer lifespan compared to other types of lighting fixtures.
The benefits of using a T8 fluorescent fixture compared to other types of lighting fixtures include energy efficiency, longer lifespan, and better color rendering.
Fluorescent lights may not come on fully due to issues with the starter, ballast, or tubes. To address this, you can try replacing the starter or ballast to see if that resolves the problem. If the issue persists, it may be necessary to replace the tubes as well.
2-tube fluorescent light fixtures offer several benefits compared to other lighting options. They are energy-efficient, providing bright light while consuming less electricity. They also have a longer lifespan and produce less heat, making them a cost-effective and environmentally friendly choice. Additionally, fluorescent lights are known for their consistent and flicker-free illumination, making them a popular choice for various indoor settings.
