Now LED lighting are getting more and more popular, and there are many optional led lighting available in the market, so which lamp suitable for you? Here OKT Lighting teaches you step by step.

1. Color temperature.
Usually the LED Lighting with color temperature range from 2700 ~ 6500K, the lower value tend to yellow color (warm white), and high color temperature tend to blue white (cold white). Yellow color generally applicable to winter, suitable for bedroom, living room, dining and other occasions, used to create a warm and comfortable feeling. The blue white is brighter and clear, suitable for summer, in study room, kitchen ,office and so on.

2. Color rendering index.
Color rendering index (CRI) refers to the color reality when the object is irradiated by light, the value range from 0 to 100, and now LED lamp CRI standards are higher than 75, and we recommend to choose CRI≥80 or CRI>90. If you have atelier in your home, we suggest to buy high CRI LED Lighting  , it can better reflect the real color of painting.
