2.How do we explain “CRI” ?

RE: 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.

3.What’s CCT(colour temperature) ?

RE: 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.

5.What’s the fire rating categories ?

RE: VO-Burning stops within 10 seconds on vertical specimen; drips of particles allowed as long as they are not inflamed.

HB-Slow burning on a horizonal specimen’s burning rate <76mm /min thickness <3mm or burning stops before 100mm.

TP(b)-Slow burning rate <50mm / min for thickness <3mm.

TP(a)-Self extinguishes and flaming and afterglow should not exceed 5 seconds once source the source of flame is removed.

6.How to explain “Flux/luminous Flux “?

RE: Luminous flux is the measure of the perceived power of light produced by the LED, adjusting to reflect the varying sensitivity of the human eye to different wavelengths of light.
