1.How long do LEDs last ?
LEDs are rated by manufacturers to operate under normal conditions or 50000 hours of continuous use. As LEDs get older, they tend to dim and fade but aren’t susceptible to blinking like incandescent.
2.What’s colour temperature ?
The description used to describe the effect of heating an object until it grows incandescently. The emitted radiation, and apparent colour, changes proportional to the temperature; easily envisioned radiation, and apparent colour, changes proportional to the temperature; easily envisioned ,when considering hot meal in a forge that glows red, then orange, and then white as the temperature increases.
3.How do we explain “CRI” ?
A measure of the degree of colour shift objects undergo when illuminated by the light source as compared with those same objects when illuminated by a reference source of comparable colour temperature. The reference source has a CRI of 100.
