How to choose beautiful LED bulbs

　　During buying and using LED bulbs, we should pay attention to the following aspects:

　　First, consider configuring

　　We should choose the same size of replacement LED bulbs to ensure that it can meet its original configuration. Dimmer must be connected with dimmable LED bulbs and designed specifically for outdoor use with outdoor lights. By rating recommended by the manufacturer we can understand the purpose and to check the bulb specification where more detailed information.

　　Second, observe the lumen

　　Lumen is the illuminance (brightness) units in suitable brightness, based on the same lumen, we should choose lower the power bulbs (wattage indicates that energy consumption).  You can use a 450 lumen bulb to replace a 40 watt bulb, corresponding to 800 lumens to replace 60 watts, 75 watts 1100 lumens alternative, that even higher flows 1600 to replace 75-watt bulb.

　　Third, choose a color

　　Warm light is very lovable, so in the most widely used family, so Kelvin temperature  is about 2700-3500K. Standard incandescent will produce a warm yellow light, the color temperature of about 2700 Kelvin (K) or so. If you like this warm colors, then select the LED lights, you can choose to about 2700K LED lights around. If you prefer a cool, bright white light, you can choose 3500K to 4100K bulbs. In 5000K to 6500K, the light bulb will be close to natural light or sunlight.

　　Fourth, pay attention to CRI

　　CRI, the color rendering index, to tell you the color change light bulbs. CRI ranges from 0 to 100, at 100 incandescent bulbs close to the sun during the day. Indoor lamp CRI is generally recommended to 80, 5 points difference is negligible within. Compare LED bulbs, you can at the same temperature in Kelvin to view different CRI values.
