**lamps**which have 100 watts or lower,

**heat lamps**are often available at 250 watts, even more. Due to this difference, it's far more efficient at producing

**heat**, and this allows us to determine how much of a

**heat lamp's**250 watts of power gets converted into

**heat**.

Similarly one may ask, how much heat does a heat lamp give off?

According to the Wikipedia online encyclopaedia, a 100 watt bulb is 2.1% efficient. In other words, it produces about 2 watts of light and 98 watts of **heat**. A halogen **lamp** is a bit better. For every 100 watts you put in, you get about 3.5 watts of light and 96.5 watts of **heat**.

**Infrared Bulb**-

**150W**reaches a maximum

**temperature**of 518 degrees Fahrenheit, the Near

**Infrared Bulb**-250W reaches a maximum

**temperature**of 572 degrees Fahrenheit, and the Near

**Infrared Bulb**-300W reaches a maximum

**temperature**of 589 degrees Fahrenheit.

Also, how hot can a lamp get?

A 100-watt incandescent **light bulb** has a filament temperature of approximately 4,600 degrees Fahrenheit. The surface temperature of incandescent light bulbs varies from 150 to more than 250 degrees, whereas compact fluorescent light bulbs have a surface temperature of 100 degrees Fahrenheit.

The one true difference between the two is simply the color. **Red** casts a warm glow on its subject and the **clear** is just there, **heating** up the area. **Red** is chosen many times in food service, as it can make the food look **more** warm and inviting.
