NOTE: Some product packaging may not indicate FULL SPECTRUM LIGHTING, but the products will meet the below outlined criteria.
The term FULL SPECTRUM LIGHTING has no agreed upon standard or definition in the lighting industry. Instead, products labeled or sold as FULL SPECTRUM LIGHTING 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 lighting 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 full spectrum 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 full spectrum light bulbs, or generally any light source. A full chart of color temperatures may be found via the following link on our web site: Color Temperature Chart. Full spectrum light bulbs 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 full spectrum light bulbs give the appearance of substantially more light.
Fluorescent full spectrum 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 full spectrum 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 full spectrum light bulbs sold on our site as full spectrum shall meet the following criteria:
