For the purchaser, there are many parameters that need to be looked at when importing a luminaire, such as color temperature, lumens, Ra, etc. In this article, we focus on lumens, warranty years and drivers for you, as this has a greater impact on price and quality.

Lumens

The lumen (symbol lm) is the international unit of luminous flux. Generally speaking, the higher the lumen, the greater the luminous flux of the light source and the lighter it emits. The higher the lumen requirement, the higher the price.

Warranty years

Generally, for luminaire products, the warranty period is 2 or 3 years. If there is a problem with the quality of the luminaire during this period, you can give feedback to your supplier and ask for a replacement. The longer the warranty period, the better the quality of the product and the correspondingly higher the price.

Driver

The driver is the conversion of the constant current voltage to the DC voltage required by the lamp beads.

According to the different structures, the driver is mainly divided into isolated, non-isolated, DOB and linear four kinds. The non-isolated driver is smaller and cheaper; the linear driver is very popular in the European market due to its low cost and easy to pass EMC certification.

Generally speaking, non-isolated drivers can generally meet the purchasing requirements. Isolated drivers are more expensive, so if you have higher requirements for quality, you can choose isolated drivers.

* For floodlight products you may be concerned about the construction of the product to see if the driver can be taken out to avoid problems with the driver causing the whole floodlight to be unusable. The new floodlights are now mainly of a sealed construction, which makes it impossible to remove the driver. If you require this, you will need to pay special attention when purchasing.

Depending on the working range, the driver can be divided into wide voltage driver (85V-265V), narrow voltage driver (175V-265V), single voltage driver (220V) and low voltage driver (3.7V, 5V, 12V, etc.), where the wide voltage driver has a wider working range and can achieve basically the same power, but actually costs more.

* For lamps, downlights, floodlight products, Dubai is generally narrow voltage, Saudi Arabia few parts with wide voltage.

I believe that through the above introduction, you must have a certain understanding of the parameters of lamps and lanterns that need to be noted when importing. If you have any questions, please feel free to contact us directly or visit our website for more information: www.hbsocket.com.
