How to check the actual wattage of lamps? how to identify products with false parameters on the market?

Power fictitious standard means that the power marked by the lamp is greater than the actual power used by the lamp, and we all know that the higher the power of the same type of lamp, the more expensive the price. The root cause of false bids is to increase the price, or pretend to have a high cost performance in the same price, attracting the attention of customers.


OKES has these instruments that can test the parameters of lamps: 


1.Integrating sphere: It can test the CIE Colorimetric Parameters, Photometric Parameters , Electric Parameters (power, power factors, etc.) of the luminaire.


2.Multimeter: Generally, the multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, and some can also measure AC current, capacitance, inductance and some parameters of semiconductors.
