Why Conduct A Test Cabinet Light Strip Sample Order?
After searching and picking up from the “product ocean” of cabinet light strips. you propably negoicate with the selected suppliers on your demands and decide to make sample orders from selected suppliers, which is a must step before your bulk order.
A few days later, you may have received samples. It is easier to conduct a product quality test for a professional buyer with LED lighting industry for years. Because these buyers tend to have professional facilities or test machine to for assistance. But for those newly-entered buyers, it may be difficult for them to tell the quality of the light strips, and then make a smart decision for bulk order, which may cause negative impact on their business.
Only you make a smart choice from your sample orders, then you will be profitable from bulk order.
How to conduct a test without large equipments ?
As a new game player in LED lighting industry, here are some effective ways to ensure we can select a reliable product supplier.
1. Packaging and labeling
Check if the packaging clearly indicates the basic information of the product, such as rated voltage, rated power, luminous flux, color temperature, color rendering index (CRI), etc.
The product packaging should have CCC or corresponding regional safety certification marks, such as UL in the United States ETL certification, European CE certification, etc. indicate that the product has passed safety and quality standard testing.
2. Light source quality
The light source of high-quality LED lights usually uses well-known brand chips, such as wafers, Osram, Philips, etc., which have high light efficiency, good stability, and long lifespan.
Observe whether the arrangement of the lamp beads is neat, whether the color is consistent, and whether there are dead lights or obvious color differences.
3. Heat dissipation design
High quality LED lights have a good heat dissipation structure, such as aluminum alloy heat sinks, thermal conductive silicone grease, etc., to ensure that heat can be effectively dissipated during long-term use, avoiding high temperatures affecting the lifespan of LED light sources.
4. Drive power supply
High quality LED lights are usually equipped with a constant current drive power supply, which can stabilize the output current and prevent voltage fluctuations from affecting the brightness and lifespan of the light source.
Check if the power supply has EMC (electromagnetic compatibility) and safety certification to ensure safe use.
5. Starting performance and brightness stability
There should be no flickering phenomenon during startup, the brightness should be stable without obvious fluctuations, and there should be no overheating phenomenon.
6. Appearance and Structure
The shell should be flat and smooth, without burrs or cracks, the plastic material should be odorless, and the metal parts should be free of rust.
