What Wattage/Energy Does a Heat Lamp Use?
Other than the consumption of the heat lamp, it is essential to consider the amount of heat given. Factors such as wattage and efficiency play a major role in determining the heat output of your lamp. That is to say, suppose you are using a 250-watt lamp with a 10% efficiency, the amount of heat produced would be at 225 watts.
Are Heat Lights Expensive to Run?
Heat lamps operate on a higher wattage compared to the other light bulbs. However, they are relatively efficient in energy consumption since they do not use up much power. But since these lamps give extra heat they consume slightly more electricity in comparison to the other heat bulbs.
Heat Lamp Electricity Cost Estimates
Most electricity companies charge an average of twelve cents per kilowatt-hour (kwH). If we do the math we we can figure out that the electricity cost to operate a heat lamp with a 250w rating for 24 hours, 30 days would be $ 21.60.
That would mean that the electrical energy cost of running a 250-watt heat lamp would be somewhere around 182.5kWH × $0.11855/kilowatt-hour = $21.64 per month.
How Much Heat Does a Lamp or a Light Bulb Give Off?
Fluorescent bulbs produce 75% less energy than incandescent bulbs. The heat produced by the incandescent bulbs comes from heating the metal filament in a glass of inert gas to an approximate temperature of 4000 Farads. The heat energy emitted by the incandescent lamp bulbs is between 90 to 98 percent of the bulb’s energy.
This percentage is, however, subject to the surrounding airflow, bulb shape, and bulb material. For example, with a common 100-watt bulb, the internal temperature goes to a maximum of 4600F, producing an external bulb temperature ranging from 150 F to 250 F.
How much energy does a heat lamp use?
The energy used depends on the power drawn by the bulbs used and its efficiencycy. A light bulb’s efficiency helps determine the amount of energy that successfully turns into light and heat and the amount that goes to waste. The efficiencies of different bulbs are as below:
- LED light bulb-15% ɳ
- Incandescent light bulb-2.6% ɳ
- Fluorescent light bulb-8.2% ɳ
As you can see, LED bulbs are the least efficient, while incandescent bulbs are the most efficient.
What Is the Difference Between Red and Clear Heat Lamps?
All the heat lamps raise the temperatures of a given region by emitting infrared radiation. These lamps also have specific features which affect heat output, such as reflectors, water-cooling, and twin tubes. These infrared heaters have built-in reflectors that emit focused high-intensity radiation. The lamps exist in three categories which include clear, red, and frosted.
Besides the infrared radiation heat it emits from its infrared bulb, the red lamp also casts a warm glow on objects the light falls on, making them suitable for use in food service businesses. The difference between the red lamps and the others is just the glow cast on the objects by the red heat lamps.
