- Color rendering: For a light source, the extent of the agreement between the perceived
color of a surface illuminated by the source and that of the same surface illuminated
by a reference source under specified viewing conditions, measured and expressed
in terms of the chromaticity coordinates of the source and the luminance of the
source in agreed spectral bands.
- Lumens: also known as luminance. It is a measure of the amount of light a bulb produces
near the beginning of usage.
- Luminous efficacy: The ratio of the total emitted luminous flux, in lumens, to the
total electric power consumption in watts.
- Luminous flux: The rate of flow of light per unit of time, especially the flux of
visible light, expressed in lumens.
- Luminous intensity: The luminous flux density per solid angle as measured in a given
direction relative to the emitting source. The customary unit is candlepower, the
SI unit is the candela.
- Life Hours: an average rating in hours when approximately 50% of the bulbs in the
test fail. The testing assumes normal operating conditions.
- Color Temperature: The measurement of color expressed in Kelvin (K). The lower the
Kelvin rating, the “warmer” or more yellow the light. The higher the rating, the
“cooler” or more blue the light. For residential use, we recommend our day white
and natural white colors.
- Glare: The sensation produced by brightness within the visual field that is sufficiently
greater than the luminance to which the eyes are adapted. Glare can cause blurred
vision, discomfort, headaches or loss in visual performance and visibility.
- Voltage: a measurement of electrical potential and is the force that pushes electrical
current through a conductor.
- Wattage: the rate at which energy is taken from an electrical source or dispersed
by a load. LED Bulbs are rated in Watts to indicate energy consumption.
- Illuminance: The density of luminous power, also called “illumination.” One lumen
of luminous flux uniformly incident on 1 square foot of area produces an illuminance
of 1 footcandle. In SI units, one lumen of luminous flux uniformly incident on 1
square meter of area produces an illuminance of 1 lux.
- Ingress protection rating: The IP code or IP rating defined in the international
standard IEC 60529 that classifies the level of protection that electrical appliances
provide against the intrusion of solid objects or dust, accidental contact, and
water.
