During the production of Douai , it adopts a fully automatic sorter machine to screen and classify predictive parameters such as voltage, wavelength, and brightness.
m******g
During the design stage of Douai , static electricity protection is considered. It has passed through the electrostatic precipitation process.
g******b
The bulb of Douai is of well-crafted. Through comparison of a large amount of experimental data, the bulb is manufactured to have excellent luminescence performance.
a******f
The production of Douai includes overall three parts: the production of filament, the bulb, and the base, which is highly automated.
z******z
Before the delivery of Douai , it undergoes a strict brightness test. It is analyzed and screened by brightness analyzer to eliminate unqualified one.
p******v
The product features a long service life. Its circuit board adopts high-performance electrical components, minimize the aging effect that caused by long-time working.
