What is the difference between fluorescent light and natural light?
Natural light, which produces heat and color, comes from the radiation given off by the sun. It is then filtered through the Earth's atmosphere and absorbed by plants. Artificial light sources can consist of a filament that uses electricity or halogen gas to glow, or an electronic device that emits light.
What type of light is fluorescent?
gas-discharge lightFluorescent light bulbs are a specific type of gas-discharge light (also known as a high intensity discharge, HID, or arc light). CFL is an acronym that stands for compact fluorescent light. Standard fluorescent lights are available in tubes (generally 48 to 84 inches in length). CFLs are much smaller.
Is sunlight different from artificial light?
Natural light is fundamentally different than the artificial light sources which we use in our homes, offices and schools. (1) Natural light is full spectrum, which means it contains all the colors of the rainbow, as well as wavelengths (colors) that we cannot see (infra-red and ultra violet).
What is the difference between daylight and sunlight?
Daylight would be the clear, bluish light coming in through a north facing window. No direct sunshine coming in, just the light from the crisp, blue sky. Sunlight, on the other hand, has a warmer, yellower quality to it - imagine the soft, early morning sun rays streaming in through your windows.
Why is the reflector on a lamp selective?
The reflector on the bulb is selective so that the visible and UV is reflected towards the cell but most of the infrared radiation isn't reflected and passes out the back of the bulb.
Can mercury lamps emit IR radiation?
They are designed to make impression of a white light, with negligible content of long wavelength radiation. On the other hand high pressure mercury lamps are often used as a source of IR radiation. Yes, you would have to heat up a black body to 6500K and then filter what our atmosphere is filtering.
Is FL still in the spectrum?
FL have mostly still some peaks in the spectrum but there are ready to use products (LifeLite, True-Light,...). There are also some LED products trying that but mostly using a cold white led and a amber or red one. They often lack in the turquoise part of the spectrum.
Is it difficult to make a light source that exactly matches the AM1.5 spectrum?
It is difficult to make a light source that exactly matches the AM1.5 spectrum and with the necessary illumination intensity. There is often a considerable amount of variation between the spectrum of the lamp and the required AM 1.5 spectrum.
What is the Kelvin of a light?

What are Full Sunlight Spectrum Bulbs?
Full spectrum light bulbs are designed to emit light corresponding mainly to the visible portion of the solar spectrum. In order to have a more accurate reproduction of the sunlight spectrum, these lamps need to produce infrared and ultraviolet light as well.
Which type of lamp has a good color temperature?
Other types of lamps, such as the Mercury-Vapor lamps and High Intensity Discharge lamps (HID), may have good color temperature but their light spectrum appears fractured.
What is a compact fluorescent lamp?
Fluorescent lamps display continuous spectra combined with discrete lines or spikes. The availability of such a wide range of CFLs is due to the mix of phosphors inside the tube. Each of them emits a discrete color, thus the addition of extra phosphors increases the CRI of the lamp (~80) along with its price.
How to choose a full spectrum bulb?
First of all, the lighting design engineer (or the consumer) must pay attention to the spectrum graph of the lamp. The spectrum must be as continuous as possible, without any discontinuities or spikes on the line of the spectrum graph. These lamps also emit infrared and ultraviolet wavelengths, which should be blocked by protective filters, in order to be safe for commercial use.
What is the CRI of a light bulb?
The CRI or Color Rendering Index is a measure of the bulb’s ability to reproduce the colors of an object in comparison to the colors observed in natural light. This ability is measured with an index rating ranging from 0 to 100, where the value 100 corresponds to the color rendering of sunlight. A bulb with a minimum of 90 CRI is thought to reproduce sunlight quite satisfactorily.
