1. Look at the chromaticity of the lamp

Output power determines brightness. Generally, the screen brightness of LED lights with higher output power is much brighter than that of LED lights with lower output power, and the price will be relatively higher.

2. Understand the colloidal solution of lamps

The colloidal solution of ordinary LED lamps generally uses epoxy resin glue, and high-quality LED light sources generally have the function of anti-UV and fire retardant. Because lighting fixtures with anti-UV and fire retardant are relatively expensive, there are relatively few high-quality outdoor LED lamps.
 

3. Master the light wavelength of the lamp

The wavelength of light of the lamp determines the color of the light. Manufacturers with good user reviews and qualification certificates generally produce products of very high quality. They usually use a spectrometer to produce LED lamps with very authentic colors. LEDs produced without a spectrometer will have inconsistent wavelengths, and of course, inconsistent colors.

4. Master the street lamp power supply

Generally, lamp damage is due to the burning of the street lamp power supply, so the street lamp power supply plays a very important role in the service life of an entire LED lamp. Manufacturers will design different power supplies according to different design points, which are mainly divided into two types: constant current power supply and voltage regulated power supply. 5. Look at the anti-static level of the lamps and lanterns

LED light sources with weak anti-static level have relatively long service life. Generally, LED lamps with anti-static exceeding 700V can be used as LED lighting.

6. Understand the heat pipe radiator of the lamp

The shape of the lamp can determine the actual effect of the radiator. If the external or embedded lamp is made of aluminum, it will have a very good restricting effect on the thermoelectric effect of the lamp. Because the ambient temperature determines the service life of the LED lamp beads, processing the thermoelectric effect can effectively extend the service life of the LED lamp.

7. Understand the leakage current of lamps

LED is a unilateral conductive light-emitting object. If reverse current occurs, it can be determined as a short circuit. If the leakage is serious, the service life of the LED lamp will often be shortened and the price will be correspondingly more affordable. LED lights mainly rely on processing chips to light up. Different chips have different prices. If you want to choose a processing chip with better quality, you can choose imported products.
