How to identify high-quality LED lighting?
Nowadays, more and more offices, hotels and commercial premises are equipped with LED downlights for lighting, which are becoming increasingly popular because of their suitability for indoor lighting and energy efficiency.   
 
But how do you judge a quality LED downlight? Many consumers report that they don't know how to evaluate a quality LED downlight - after all, it's not a good idea to trust the lamp manufacturer completely. This article will clarify how to scientifically judge a high-quality LED downlight from an objective point of view.
 
01 A comprehensive look and parameters
 
When buying an LED downlight, the first thing to do is to check the lamp's appearance, including whether the surface of the lamp body is smooth and tidy and whether the artistry is superb. To meet a specific requirement, the lamp body should be carefully measured for various conditions such as mounting method, length, diameter, etc. Bledlighting's suppliers use German technology in die-casting and printing technology to ensure a smooth surface and high quality in coloration.
 
02 Strobe condition 
 
The strobe of a downlight can be harmful to your eyesight. Here's a tip for testing the strobe level: when you get an LED downlight, you can plug it in and light it up, use the slow-motion function of your mobile phone camera to get close to the light-emitting surface and record a video, then you can watch the recorded video to see if there is a flicker on the video, so you can tell if the light is producing strobe. tridonic, Orsam and some of China's best driver brands can achieve THD <18% in specific parameters. Therefore, Bledlighting's luminaires are all strobe-free.
 
03 Comparison of light quality
 
To check the quality of light, you can turn on several LED downlights of the same type from the same manufacturer at the same time and observe their luminous color and brightness. Manufacturers of high-quality light sources strictly control the consistency of their light color. If there is a significant difference between them, this means it is an inferior product. Bledlighting uses mainly lamp bead brands widely known in the lighting industry, such as Citizen, Luminus. Technically speaking, high quality LED downlight from the same manufacturer should have no problems with inconsistent color and brightness. 
 
04 Heat dissipation performance
 
A direct way to check the thermal performance is to measure the temperature of the LED chip during operation. The crystallization point temperature of the light sources currently used by Bledlighting is below 85°C as standard in the specification, thus controlling the quality of the product. It is recommended to use the "half-hour illumination method" to measure the junction temperature to determine the merits of the luminaire's heat sink. 
 
05 Light Decay
Light fade is the reduction of the light intensity of an LED luminaire compared to the initial light power after a period of lighting, and it cannot be recovered, i.e., the reduced part is called the light fade of the LED luminaire (the cause of light fade varies for different types of luminaires). Bledlighting's suppliers make a corresponding LM80 report on each product and LM79 for the whole lamp to illustrate Bledlighting's luminaires within the normal range of light decay. This time frame is based on five years to prove that Bledlighting's products are of high quality.
