What else can I help you with?
Does a burned out bulb use electricity?
Assuming it's a filament (incandescent) bulb, no. When a bulb burns out, the tiny wire in the bulb is broken, and the electricity can no longer pass through the bulb. It's the same as if it was switched off.
How does light from cfl bulb compare?
When you compare a CFL (Compact Fluorescent Lamp) bulb to an LED bulb, the CFL bulb has a shorter lifespan. The CFL bulb also uses more electricity for the same brightness Also a CFL lasts longer and uses less electricity (for the same brightness) than an incandescent bulb.
Can I get an LED light installed into my incandescent downlight cans?
Yes, absolutely. As long as the LED bulb and incandescent bulb have the same base they will both fit the socket. The LED bulb will also run much cooler than the original incandescent bulb.
What is the brightness level of a 25 watt LED equivalent bulb compared to a traditional incandescent bulb?
A 25 watt LED equivalent bulb is about the same brightness as a 100 watt traditional incandescent bulb.
How efficient is a fluorescent bulb that emits the same amount of light as a 100w incandescent bulb?
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
What uses more electricity 120 or 240 volts on a 1000 watt bulb?
Watts is the product of amps x volts. As the value of voltage increases the value of amperage decreases. 240 x 4.17 = 1000.8 watts. 120 x 8.34 = 1000.8. No matter what voltage is used on the bulb, it still draws 1000 watts and this is what the utility companies base their billing on.
Do incandescent and fluorescent bulbs produce the same amount of heat?
No, incandescent bulbs produce more heat than fluorescent bulbs. Incandescent bulbs generate light by heating a filament, which also emits heat. Fluorescent bulbs produce less heat because they use electricity to excite gas inside the bulb, which then emits light.
Will a fluorescent light bulb burn brighter than an incandescent one?
Fluorescent light bulbs are typically more energy-efficient and produce more light for the same amount of power compared to incandescent bulbs. So, a fluorescent light bulb may appear brighter than an incandescent bulb with the same power rating.
Can you mix incandescent bulb with halogen bulb in same light fitting?
Yes, the halogen bulb would provide about 30% more brightness (lumens) for the same electric power rating. So 70 watt halogen is about equal to 90-100 watt incandescent.
How efficient is a 100 watt light bulb?
A 100-watt incandescent light bulb is not very efficient, as it converts only about 10% of the electricity it uses into light, with the rest being lost as heat. It is more energy-efficient to use LED or CFL bulbs, which can produce the same amount of light as a 100-watt incandescent bulb while using significantly less energy.
Are South African incandescent light bulb fittings the same size as in the US?
yes
Can you put a 10.5 LED bulb in a basic 40 watt intermediate lamp base?
An LED bulb that replaces a basic bulb must have the same working voltage and the same type of fitting. A 10.5 watt LED will draw less power and produce less heat than a 40 watt incandescent, but not all LEDs are dimmable.
