What you need to know when choosing LED lights

There are several basic concepts and parameters that you need to be familiar with before choosing. In some cases, the features of the structure and the principle of operation of these devices do not correspond to the general characteristics of other types of lamps.

  • Glow Brightness

The higher this parameter, the more light the lamp gives. The approximate brightness of an incandescent lamp in100 watts is 1500 lumens. Based on this indicator, it corresponds to a 12W LED lamp.

  • Lighting angle

One of the main parameters by which led lighting differs from incandescent lamps is the directivity of the glow. When the diodes are located on the same plane, the illumination in the form of a light spot is obtained. To increase its angle, it is necessary to arrange the diodes accordingly.

  • Power consumption

The driver installed in the lamp and powering the LEDs has its own efficiency. If 1 watt of power is required per LED, then a 4-diode lamp will not necessarily consume 4 watts.A poor driver with an efficiency of 50% will take another 2 watts, so the total power can be 6 watts.

  • Lamp Hours

Manufacturers indicate different lamp hours from 30,000 to 100,000 hours, but this does not mean that the lamp will stop working after this period. During this time, LEDs usually have about 70% of their brightness. If the driver works normally, then, for example,e27 LED lampscan last 5 times longer.

  • Color Coverage

The best option when this indicator is close to 100. Normally, the coefficient of 75-95 is considered to be normal for LEDs, but in low-quality lamps it is much less, which creates gray-green lighting.

  • Power consumption

The driver installed in the lamp and powering the LEDs has its own efficiency. If 1 watt of power is required per LED, then a 4-diode lamp will not necessarily consume 4 watts. A poor driver with an efficiency of 50% will take another 2 watts, so the total power can be 6 watts.

Power consumption affects the brightness of the glow, but not directly. It depends on the type of LED, optics, color temperature.So, 6-wattLED lamps with e14 base, a good driver, high-quality LEDs and modern optics can shine more brightly and last longer than 10-watt with plastic optics, a bad driver and outdated LEDs.
