FAQs:
Q: What do "cool white" and "warm white" mean, and what is CCT?
A: The Color Correlated Temperature (CCT) is given in the description led ligh/ lamp/bulbs.By comparison, a typical incandescent bulb has a CCT of 2800K. A typical halogen is a bit higher, maybe 3500K. Daylight white is 4500K and a cool white fluorescent is 6000K or more.
The human eye adapts to background light so that even a daylight white bulb will look slightly blue in a room illuminated mainly with incandescent bulbs. Similarly, an incandescent bulb will look very yellow or even orange in midday sunlight.
Q.What is Lumen(lm)?
Lumen is the international(SL)unit of luminous flux, a measure of overall light emitted by a light source.
Q. What is Candela(cd)?
Candela is the international(sl) unit of luminuous intensity,a measure of light emitted by a light source in a particular direction. Any given light source will have different luminous intensities in different directions considered.
Q.What is Beam Angle?
Beam angle is the angle between two directions for which the luminous intensity is 50% of the maximum intensity as measured in a plan through the nominal beam centerline. Beam angle of a bulb gives an idea of how the light beam spreads away from the beam center.
