AMP

AMPERE-HOUR

ANODIZING

Full-Spectrum (FS)

the term is used to define a light source with a CCT of 5000K or higher and a CRI of 90 or higher.  FS lamps are fluorescent, and they often have enhanced levels of UV. Only lamps that meet these specifications should be called FS.

Lamp

The Word 'Lamp' refers to a 'light bulb' or a 'light tube'.

Light

Infrared light, ultraviolet light, Gamma rays, X-rays, microwaves and "radio waves" are names given to other radiant energy wavelengths; and all call can be considered "invisible light" to a human eye.

Human eyes can detect a tiny range of visible wavelengths.  These visible wavelengths are actually color.  The shortest wavelengths are blue, and the longest wavelengths are red.

The human eye senses the wavelength and translates it to a never signal sent to a special section of the brain, where our minds perceive it as a color.  Further processing by specialized sections of the mind, translates the incoming color and shapes into recognized objects, and images.

Violet color has a wavelength of about 0.4 micron, yellow colors around 0.6 microns, red colors around 0.65 microns in length.  Human eyes cannot see a wavelength longer than 0.7 microns.

Infrared Light

The range of infrared light waves is a thousand times wider than human-visible light.

First are the "very near infrared light", which are from 0.7 to 0.9 microns.  Infrared Film, standard video cameras are sensitive to 0.7 to 0.9 microns.  'IR' Remote Controls Use This Range Of Infrared Light Waves.  The "Auto-Focus" Feature Of Many Cameras, Camcorders, Video Cameras, And Other Devices Use This Range Of Infrared Light Waves.

Next are the "near infrared" wavelengths at 2.4 microns.

Longer infrared wavelengths are emitted by hot objects, and have thermal properties.  Humans can detect these wavelengths as heat.

There are many types of devices to detect and measure infrared light.

Since Infrared Light Is Radiant Energy, It Has The Same Properties As Human-Visible Light.  Therefore Infrared Light Can Be Focused, Reflected, Aligned With Optics, And Polarized, Like Human Visible Light.
