What is an Incandescent Lamp?
An incandescent lamp contains a filament wire, typically made from tungsten. The bulb operates by heating the filament until it glows white. Incandescent lamps are the bulbs seen most commonly in households and other applications where a great intensity of light is not needed.
Can Incandescent Lamps be Used as Grow Lights?
An incandescent bulb would be ineffective as a grow light for several reasons. It operates with a limited light spectrum, thus depriving plants of the specific light recipes necessary to thrive. Incandescent lamps are also highly inefficient in their lumen-to-watt ratio, and they produce far too much heat per watt.
