What is Full Spectrum Light?
Full-spectrum light covers the electromagnetic spectrum from infrared to near-ultraviolet, basically all wavelengths that are beneficial to plant or animal life; most representatively, sunlight is considered full spectrum. Full spectrum lamps simulate the full spectral power distribution range (both visible and ultraviolet) of natural outdoor light.
Full spectrum lighting is most beneficial for those performing tasks reliant on excellent color discrimination: interior design, graphic arts, crafts, sewing, detailed tasks, painting, and any job that requires detailed color separation.
Color Temperature & CRI (Color Rendering Index)
Full spectrum light is simply, simulated sunlight. Full spectrum light optics are best measured using both its color temperature and its CRI number. The Sun at noon has a natural color temperature of approximately 5,500K, and a CRI of approximately 100.
Seasonal Affective Disorder is a disorder that is brought on by a change in seasons, or a decrease in exposure to natural sunlight. SAD's symptoms include loss of energy, moodiness, and in some cases severe depression. Phytotherapy, or the use of light boxes which emulates natural sunlight, can be a beneficial natural remedies for SAD, according to many behavioral experts including the Mayo Clinic. SAD affects half a million people every winter between September and April, peaking in December, January, and February. The “Winter Blues,” a milder form of SAD, may affect even more people..

No other kind of light can compare to natural light – that is, the light that comes from the sun. It is a good thing that there is a man-made light that effectively mimics this, allowing you to enjoy it even when the sun does not decide to shine on a given day. This is light that comes from a full spectrum lamp.
Great for reading and crafts. One of the best features of a full spectrum lamp is that its head can be turned and adjusted so you can just direct it to properly light up whatever you are working on. It gives you a crispier look at words and colors.
Now that you know how these non-glaring light fixtures are perfect for performing your routine day to day tasks, it’s time to know how to buy a full spectrum lamp. You have to find good lighting that is safe, easy on the eyes, and comfortable as you do your daily chores. Although it could cost more than other kinds of lamps, the safety you get from this definitely makes up for its price.
So, what are the tips you have to know in buying a full spectrum lamp?
Otherwise known as “daylight” lighting, a full spectrum light has a very high color temperature, approximately the kind that you see on a bright and sunny day. It ranges from 5000K to 6000K and can be a very pronounced blue. It used to be lighting that is considered too harsh for the indoors but there are already variations that are good enough to be installed in homes and offices.
The full spectrum index provides an analysis of the peaks and troughs given by the SPD. It then comes up with an average. The average gives the lamp its score.
Consider the full spectrum lamp with a low score to be the best choice as it has an even distribution of wavelengths.
Ideally, lamps with scores of 2.0 or less are the “true blue” full
The lumen is the measure of the total amount of light that is emitted by a source. This is often used along with wattage to determine the luminous efficiency of a light.
More lumens, the brighter the light source is.
Full spectrum lights can range from 2000 to 2500 lumens.
Yes, buying a full spectrum lamp is an investment but looking at it long term, using such a light practically becomes free. This is because you will not have to replace it at much as you would with other kinds of light. Also throw in the fact that it uses up less energy. Overtime, this makes for an investment that will pay you back!
