Verilux light boxes use a full spectrum light bulb that mimics daylight at 6,500K and provide a light intensity of 10,000 lux, which is the clinical standard for effective light box therapy for treating seasonal mood disorders (see more on the specific type of light therapy that Verilux speci...
A daylight lamp is term used by marketers to describe lights that are meant to mimic the properties of actual sunlight. They are often referred to as full-spectrum lights, but although they generally produce light throughout the spectrum, they often do not have an even distribution of light ...

What is a Spectroradiometer: A spectroradiometer is a device designed to measure the “absolute radiation” energy emitted by a light source. This energy could possibly include the entire light spectrum: visible light, UV light, and infrared light. ...
He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).He does not acce...
This not only sets the right mood but also saves energy when full brightness is not needed. Often, you can get more than one feature in a single bulb; for example, many wi-fi enabled bulbs also have color change or dimming features. Smart light bulb benefits Smart bulbs offer a number ...
Incandescence is light emitted by a hot object, while iridescence is a colorful phenomenon caused by light waves dispersing and reflecting off a surface or through a medium.
The closer to the light source, the higher the lux reading. This is due to the dispersion of light as one moves away from the light source. Therefore, when you look at a lux rating for a light bulb, you must always make sure there is a distance associated. For example, you may see...
The word "year," is normally a unit of time, but light-years measure distance. M. Aurelius/Shutterstock A light-year is a way of measuring astronomical distances in space. That doesn't make much sense because "light-year" contains the word "year," which is normally a unit of time. ...
A grow light is an artificial light source designed to stimulate plant growth through photosynthesis. It’s a vital tool for indoor growing, providing the necessary light spectrum plants need when natural sunlight is insufficient. 3 Different Types of Grow Light ...
