Now LED lamp is mainly used for all kinds of commercial space lighting and architectural decoration lighting, etc. At the same time to shoot the light is divided into low pressure and high pressure, proposal consumer had better choose low voltage lamp, due to low pressure lamp life relatively longer, the higher light efficiency. Shoot the light of the general lighting power factor to decide, good lamp power factor can reach 0.99, but the price is much expensive.
Q:Household LED lamp, ceiling lamp, when installation, both can zero wire?
Basic products such as LED ceiling lamp, the lamp generally driven by constant current power supply, input is 85-265 - v ac, so don't points are negative.

Color temperature is defined in absolute blackbody, absolutely blackbody radiation and light radiation in the visible area all at the same time, the temperature of blackbody is called the color temperature of light source. Low color TPS source is characterized by energy distribution, relatively more red radiation, commonly referred to as "warm light"; Color temperature increase, energy distribution, the proportion of blue radiation increases, often referred to as "cold light". Some commonly used color temperature of light source are as follows: standard candle is 1930 k (kelvin temperature unit); Tungsten is 2760-2900 k; Fluorescent lamp is 6400 k; Flash is 3800 k; At noon the sun is 5000 k; Electronic flash light for 6000 k; The blue sky is 10000 k.
