To have enough bulb or surface area to produce the required amount of light.
no
wire
That would be approximately a 30 watt CFL.
The single most important power saver product of the last 20 years is the energy saving light-bulb. They use 1 fifth to 1 third of the energy of a conventional light-bulb and last 6000 to 15000 hours compared to 750-1000.
you can tell if an electronic is an energy saver by looking for the energy star.
Its a coiled tungsten filament.
It shouldn't, but if the bulb is being used to heat the lizard's terrarium it won't provide enough heat and the lizard may be lethargic. Use a proper terrarium heating lamp, not a CFL or LED bulb for that purpose.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
I am not sure. But what I know is that LED or LED lampen is an example of an energy saver lamp.
They have to be coiled in order for them to be long enough to produce enough heat, which produces the light in a small space. Otherwise the light bulb would have to be much larger.A filament bulb is coiled to allow a much longer filament to fit into a tiny space. It also reduces the amount of gas which flows across the inner portion of the filament.
Energy Saver freezers can save you over fifty dollars a year in electricity.
A spring you see in a pen. It has potential energy until you click it, then the coiled spring becomes kinetic.
