Simply put, LED downlights are actually household lighting fixtures (bedroom, living room, balcony, etc.) in daily life, but the light source is no longer traditional energy-saving bulbs, but uses LED light sources to illuminate, LED downlights The choice is no longer as simple as traditional energy-saving lamps (incandescent lamps), so the factors considered are also different, so how do we choose LED downlights?
LED downlight purchase key 1: radiator.
The speed of heat dissipation determines the luminous attenuation of LED downlights and the length of their service life. The radiator is too small and will cause high temperature to accumulate inside the light source, while the lamp beads work at high temperature for a long time, the luminous attenuation is very fast, and the service life is very long, therefore, when choosing LED downlights, it is recommended that you choose aluminum shells, because the heat dissipation coefficient of aluminum is relatively high, and the heat dissipation is relatively fast, which can ensure the normal lighting of LED downlights.

LED downlight purchase key 3: the quality of lamp beads.
In addition to considering its material and driving power, the purchase of LED downlights must also consider the quality of lamp beads. The quality of the lamp beads determines the lighting effect of the lamp. The packaging process affects the quality of lamp beads, heat dissipation and other key factors. At present, the LED chips sold in the market are both domestic and imported. Generally speaking, different brands have a big difference in price and different lighting effects. It is recommended that you purchase with caution.
