1. The level of the mold can be seen from the finish of the product components, so as to indirectly see the quality of the LED track light. At present, the mainstream COB track lights on the market are basically ideas, random assembly of several scattered parts, each part is different in color, and the process of connecting parts is rough.
2. See whether the solder joint has the same size, whether there is a spike, etc.
3. See if there are defects and defects.
4. the main parameters of the LED track lamp are luminous efficiency, color index, the current indicator of luminous efficiency is 100-150LM/W, must be greater than 100LM/W, but this indicator is in the growth period, by next year will reach 150-250LM/W. The color rendering index can reach 80, and there is no need to pursue more than 90, unless you are engaged in painting and other work with high color requirements.
5. Look at the power, the mainstream cheap track lights on the market basically use 24W virtual label 30W.
6. Light quality: no secondary spot, clean edge, smooth evolution of the main and secondary spots, the main and secondary spots are obviously different and strong and clear boundaries, of course, it is also necessary to consider whether the performance between the individual spots is consistent, the consistency of the main and secondary spots' color rendering ability, such as the light Angle and accurate shooting
7. Beam Angle: In order to take care of the understanding of most laymen, let's start from the traditional aesthetic, that is, led most of the way to imitate the traditional point light source. The difference in light output area is not very large, so it is relatively standard, and it is also classified as 12/24/40 including its subdivision. More than 40 degrees of the general should not be analyzed its light plate shape, really no obvious boundary, the key lighting beam Angle is recommended to use 12 degrees, such as clothing store model display, product display is recommended to use 24 degrees. At present, most manufacturers do not have clear Angle positioning, and buy reflective cups in the accessory market, and the secondary optical reflection cannot be matched with the COB chip and the fixed bracket, and the deviation from 12 degrees to 20 degrees.
8. Appearance structure aesthetics, based on the different understanding and demands of each manufacturer of the product, the appearance of the product is a concept without a line and no way to accurately define, for us is how to look at the details and proportions, good products in the structure can not blindly sensationalism, as long as the premise of meeting the heat dissipation composition, Minimize unnecessary material waste and transfer costs to consumers, a good product should be good at core, simple in shape, to create value for consumers.
