What else can I help you with?
What uses more electricity a lit light bulb or an empty socket of the same rating switched on?
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
Why does a light bulb light up immediately after you turn on a switch even if the switch was a long way from the bulb?
When you flip the switch, it completes the electrical circuit and allows current to flow instantly through the wires to reach the light bulb, causing it to light up. The speed of electricity traveling through wires is almost instantaneous, so the light bulb lights up immediately after the switch is turned on, regardless of the distance from the switch to the bulb.
What causes the left tail light not to get brighter when braking even though both bulbs light up when the lights are turned on on a Dodge Stratus?
Many taillight assemblies are equipped with bulbs with dual filaments, one for tail lights and one for brake lights. If you have one bulb with two filaments, then the problem you describe sounds like the brake light filament in the left bulb is burned out but the tail light filament is working.
How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?
You can prove it by using an energy monitor that measures the actual energy consumption of the light bulb. The wattage directly correlates to the amount of energy used by the bulb, regardless of its physical size. A higher wattage bulb will consume more energy than a lower wattage bulb, even if they are of the same physical size.
How long does a filament light bulb last?
Every once in a while, you will get a dud, but for the most part they are intended to last for up to 10,000 hours. For comparable Lumens, they save about 75% of the energy that a regular filament based incandescent (the regular kind) will use. Even with the duds, it saves you significant amounts of energy. Get a good bulb, though. You're going to want to like the light quality and a good bulb will last longer. You will save money even if they're giving away the incandescents. Ideal conditions for a compact fluorescent bulb (CFL) are when the bulb comes on, has a chance to warm up, and then stays on. Closet lights will burn out sooner (per hour of use, but since they're used so less frequently), but you will still save energy. Modern bulbs come on instantly, but they take about 30 seconds to heat up. Best of luck!
Why is the light not working even though it has power?
The light may not be working even though it has power due to a faulty bulb, a problem with the wiring, or a malfunction in the light fixture itself.

Might be the bulb under the hood.
Why is the LED light not working even though it has power?
The LED light may not be working even though it has power because there could be a problem with the wiring, a faulty LED bulb, or a malfunction in the circuitry.
Does a light bulb convert light in to chemical energy?
No, a light bulb does not convert light into chemical energy. A light bulb works by converting electrical energy into light energy and heat energy through the process of electrical resistance in the filament.
Could a bad ignition switch on a 1995 Harley softail custom prevent the brake light from coming on even though the tail light is on?
Try checking the bulb, the brake light bulb may be blown.
Why is the light switch not working even though the light is on?
The light switch may not be working because of a faulty connection or wiring issue, even though the light itself is on. It is possible that the switch is not properly controlling the flow of electricity to the light.
Why is the outside light not working even though it has power?
The outside light may not be working even though it has power due to a faulty bulb, a damaged fixture, or a problem with the wiring. It is recommended to check these components to determine the cause of the issue.
My halo light on 00 dodge ram for the key switch doesn't light up even though the bulb has been replace?
If the bulb has been replaced then there could only be one solution. The fuse for the light is blown or has become loose.
What was Thomas Edison most important contribution?
