What is the wavelength of a fluorescent light?

Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.

What is cool white fluorescent light?

Cool white fluorescent bulbs have a medium to high color temperature, and produce light that is plain white or icy white in color. The highest color temperatures produce an even bluer light, which includes the reds and oranges from the previous temperatures but adds blue wavelengths that tint the overall spectrum.

What color is cool white fluorescent?

Fluorescent Lamp Colours

Description	Code	American
Warm White	530	Warm White
White	535	White
Cool White	640	Cool White
Universal White	740	–

Is fluorescent light warm or cool?

Incandescent vs. Incandescent bulbs shine with a yellowish light that most people would call “warm.” The comfortable glow of an incandescent light bulb makes people feel relaxed and content. On the other hand, traditional fluorescent lights cast a blue-white light, a “cool” light, that some people find unpleasant.

Is fluorescent light white light?

However, since ultraviolet rays are not visible to the human eyes, the inside of the glass tube is coated with a fluorescent material that converts ultraviolet rays to visible light. It is this coating that causes fluorescent lamps to glow white.

What color is fluorescent light?

Like sunlight, fluorescent light is also white light, and it is also made up of many different wavelengths.

Is cool white brighter than daylight?

Q: Is cool white the same as daylight? A: No, daylight is generally brighter than cool white. However, at the brightest end of the cool white colour temperature range, it will still be very bright.

What is the difference between cool white and daylight fluorescent bulbs?

Bulbs that provide light at around 4100K to 5000K are considered “cool white” and these start to have a slightly blue feel to them. Bulbs that provide light at around 6500K are considered “daylight bulbs” and these have a definite blue and cool sensation to them.

Is 3500K cool white?

This will tell you how warm or cool the color of the light is. 2700K – 3000K – This is the warm or soft white range, best suited for areas in the home where you want to relax or entertain. 3500K – 4500K – This is more a neutral white light range, giving a balance between warm and soft color light.

What is the difference between cool white and daylight fluorescent lights?

Cool White ranges from Yellow-White (3000K) to White (4000K) to Blue-White (5000K). Daylight ranges from Blue-White (5000K) to Bright Blue (6500K).

What is the difference between cool white and warm white fluorescent bulbs?

Warm White is a yellowish that resembles a traditional incandescent or halogen light. Cool White on its side, leans towards shades of blue and more like the light you would get from a neon.

What spectrum is fluorescent light?

Fluorescent light is on what is called an emissions spectrum. This means that its wavelengths are punctuated by lines. An incandescent bulb is on what’s called a continuous spectrum.

What is the wavelength of light from a fluorescent light?

Most fluorescent lamps made for plant growth purposes usually produce most of their spectral output in the 630 to 670 nm range. These wavelengths are red, and not as visible as shorter red wavelengths in the 610 to 630 nm range typical of fluorescent lamps designed for maximum apparently visible red output.

What is the spectrum of a yellow fluorescent light?

The spectrum is nearly identical to a normal fluorescent lamp except for a near total lack of light shorter than 500 nanometers. This effect can be achieved through either specialized phosphor use or more commonly by the use of a simple yellow light filter.

What is a helical cool-white fluorescent lamp?

A helical cool-white fluorescent lamp reflected in a diffraction grating reveals the various spectral lines which make up the light. Fluorescent spectra in comparison with other forms of lighting.

What is the best wavelength for fluorescent light for plant growth?

Both work well from red wavelengths from 610 to 675 nm, and one of them also efficiently utilizes wavelengths up to 695 nm. Most fluorescent lamps made for plant growth purposes usually produce most of their spectral output in the 630 to 670 nm range.
