How about reducing the voltage on the bulb until it just glows, maybe using a dimmer? I have done this with 12 volt bulbs in school science when demonstrating the Greenhouse Effect.nlis12 said:I am looking for bulbs that would be emitting a spectrum characterized by a color temperature of between 500K and 1000K or any kind of light fixture that only emits long IR wavelengths.
Does such a thing exist?
You can buy IR lamps for use with night vision and security equipment. LED s seem to be the way to go. Here's an example I found.nlis12 said:I am looking for bulbs that would be emitting a spectrum characterized by a color temperature of between 500K and 1000K or any kind of light fixture that only emits long IR wavelengths.

There may be a lot of wasted power in using a filament lamp in that way. LEDs will give you much more IR at the wavelengths you need.nlis12 said:Thanks!
That makes sense, if there is less voltage, less power, so the color temperature should go down.

Yea I thought about that, but LEDs don't give me the radiant power I need. (unless I had >100,000 of them)sophiecentaur said:There may be a lot of wasted power in using a filament lamp in that way. LEDs will give you much more IR at the wavelengths you need.
You can get 14W IR LED lamps. What was your application for 1.4MW of IR? Also, where would you get appropriate filament lamps?nlis12 said:LEDs don't give me the radiant power I need. (unless I had >100,000 of them)
Good idea. They also can provide lots of watts.russ_watters said:I think for this you are talking in the range of an infrared heater.
These bulbs are specifically designed for applications that require a high level of heat, such as industrial heating, medical treatments, and infrared photography. They emit light with a longer wavelength, which is more efficient at generating heat than visible light.
Regular bulbs emit visible light, while these specialized bulbs emit infrared light. This means they do not produce visible light that can be seen by the human eye. Additionally, regular bulbs have a lower color temperature, typically around 2700K, while these bulbs have a higher color temperature of 1000K.
The main benefit of using these bulbs is their ability to generate high levels of heat. This makes them suitable for various industrial and medical applications. They are also more energy-efficient than traditional heating methods, making them a cost-effective option.
Yes, these bulbs should be handled with caution as they emit high levels of heat. It is important to follow proper safety protocols, such as using protective gear and ensuring proper ventilation, when working with these bulbs. They should also be kept out of reach of children.
No, these bulbs are not suitable for household lighting as they do not produce visible light. They also emit high levels of heat, which can be dangerous in a household setting. These bulbs are designed for specific industrial and medical applications and should not be used for general lighting purposes.
