How does LED ceiling light distinguish between good and bad?

How does LED ceiling light distinguish between good and bad?

Answer:

Below, baby photoelectric dome light, open to everyone to share the internal structure:PCB light source board whole board design, soft light, uniform, no dark area, good color rendering;Aluminum pan good heat dissipation, long service life, small decline.The overall appearance gives the impression that fashionable, elegant appearance, good workmanship, high-end work, the atmosphere on the grade
You can ask the merchants and questions to resolve them!First, is it possible to guarantee two to 3 years?Second, the annual depreciation is within 5%Third, is the color rendering index above 85?Fourth, whether it is SMD beadsFifth, the light efficiency can achieve 90 lumens per watt?Sixth, is the luminous angle 180 degrees?Seventh, the most direct way, good ceiling lamp, basically 10 yuan per watt
1 see, LED ceiling lamp appearance, check whether the appearance of defects, the seal is intact, whether there is leakage phenomenon.2, look at the lampshade material, now LED ceiling lamp generally use acrylic cover, rarely use glass, acrylic face mask light transmittance is strong, and unlike glass chimney is so fragile, more light and safe.3, look at the beads, beads is the core part of ceiling lamps, domestic beads, Taiwan has imported and imported beads, domestic cheap, but the quality is not good, some of the LED lamp manufacturers in order to save costs, reduce the price of LED lamp, made of beads, the quality is certainly not guaranteed, Taiwan the relative price of domestic imports of beads beads will be more expensive, but the quality can be guaranteed, the price ratio is relatively cost-effective. Better quality beads imported from abroad, but the price is higher, customer choices. Therefore, customers in the choice of LED lamps, we can not just look at the price, we should choose from the overall cost performance.4, look at the LED ceiling lamp chassis, chassis is best to choose alloy chassis, good heat dissipation, and corrosion resistance.
Look at the structure of the LED ceiling lamp! Styles, materials, structures, materials and so forth!
The most important thing to see is the luminosity of LED, and second is the material!
