If you're building an infrared sauna or otherwise want to experience soothing heat and penetrating near infrared energy, you may be wondering how many bulbs you'll need. In this blog post, we'll provide you some information and resources to help you determine the right number of bulbs for your use.
In this blog post, we’ll explain what makes a bulb and lamp / light fixture compatible, what sorts of lamps can be used to operate TheraBulbs, and what you need to know about using a TheraBulb in a mounted light fixture.
Irradiance is the technical term for intensity of light. Irradiance can apply to both visible light, which can be seen with the naked eye, and infrared energy, which is not perceptible to the naked eye. Whether the light/energy is visible or not, its irradiance decreases as distance from the source increases. (Think of how a lightbulb seems much brighter when you are beside it than when you are across the room from it.) For this reason, irradiance data always includes the distance from the source, such as .33M, .5M, 1M. Irradiance is measured in milliwatts per centimeter squared(mW/cm2), with larger irradiance numbers indicating more energy available at that distance.
