Full Spectrum Light Bulbs
NOTE: Some product packaging may not indicate FULL SPECTRUM, but the products will meet the below outlined criteria.
The term FULL SPECTRUM has no agreed upon standard or definition in the lighting industry. Instead, products labeled or sold as FULL SPECTRUM need only meet the definitions established by the manufacturer of the lamps or the vendor selling the lamps. In determining what products are sold as full spectrum two criteria are most often considered, the C.R.I. rating and the color temperature rating (measured in degrees Kelvin).
C.R.I. stands for color rendering index. The color rendering index ranges from 1-100, with the higher numbers approaching the color replicating properties of sunlight (sunlight having a C.R.I. rating of 100). Thus, the higher the C.R.I. the truer colors appear.
Color temperature refers to the color, or light spectrum, emitted by a lamp. A full chart of color temperatures may be found via the following link on our web site: Color Temperature Chart. Lamps with a Kelvin rating of 5000 or higher produce a high number of Scotopic lumens (Scotopic lumen output is the amount of light registered by the rods of the human eye and also controls pupil size directly effecting visual acuity for tasks). Thus, 5000 Kelvin or higher bulbs give the appearance of substantially more light.
Fluorescent light bulbs sold on our site as full spectrum shall meet the following criteria:
- The C.R.I. rating is greater than 80.
- The Kelvin rating is greater or equal to 5000 degrees Kelvin.
Incandescent light bulbs sold on our site as full spectrum shall meet the following criteria:
- The light bulbs will offer 40-50% less yellow light spectrum than standard incandescents, thereby improving color rendering. **NOTE-Incandescent lamps are not rated for C.R.I. nor Kelvin temperature.
Halogen PAR lamps sold on our site as full spectrum shall meet the following criteria:
- The C.R.I. rating is 100. Click here to view our Halogen HIR Floods products.
