The light bulb can be controlled on a timer, or simply manually switched on and off. The heat can be controlled by using a thermostat. Some bulbs also provide both light and heat, and by raising the bulb the heat can be approximately controlled.
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Most light bulbs waste energy as heat. Even LEDs. Large light bulbs require more power.
I took AP Physics this year and from what my teacher told the class, from a light bulbs energy, about only 5% of it is transmitted as light. The other 95% is heat.
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
Electrical energy absorbed by the lamp's filament produces thermal energy as well as light.
It is usually controlled by a computer, controlling the intensity of a heating lamp bulb, based on a temperature sensor built within connecting to the computer (for expensive incubators, that is.)

The source of warmth in an incubator usually comes from a light bulb. There is sometimes also a fan to move the heat from the bulb around inside the unit.

Light+Heat
does the vessel where the light bulb is placed affect the heat
light and heat energy occur in a light bulb when it is turned on.
A light bulb can make heat and light.
