High Bay Led Light 240W ADC12 Die Castign Al 4KV Surge Protection SMD3030

Q1.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.

Q2.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.

Q3.Why we use the high power LED?

RE: A high power LED, sometimes referred to as a power LED, is one that is driven at current of 350mA or higher.

Q4.What’s efficacy about the light ?

RE: The light output of a light source divided by the total electrical power input to that source, expressed in lumens per watt(lm/w).

Q5.What’s LED Chips ?

RE: The light producing semiconductor device that may or may not be incorporated into an LED.

Q6.What’s LGP(PMMA)?

RE: A key component to maximize the uniformity of light, to make the backlight slim and to reorient the line or dot light source such as LED to the plate light source.
