16 advanced production Lines with supply ability up to 100,000 pieces per month seriously under managing
according to ISO9000. Every of our colleague execute exactly according to the SOP work instruction and 5S
(Seiri, Seition, Sweeping, Seiketsu, Shitsuke) is essential during our daily work.
3. LED filament bulb Strict Quality Test a.Salt spray test chamber.
Salt spray test chamber is a environmental test method by salt spray test equipment to create artificial salt mist environmental conditions , which to test product or metal material’s ability of corrosion resistance.
It is testing the LED filament lamp Lighting fitting’s cladding material whether gets rusty or not and checking the quality whether up to the quality standard.
b. LED filament lamp Vibration test machine.
Vibration test machine with the ability to identify whether the products bear the environmental vibration from simulating in manufacturing, assembly, transport and other environment cases . It’s platform helps your product meet high quality standard for LED filament bulb .
c. Programmable constant temperature and humidity chamber for led filament bulbs.
This Chamber simulates the ambient environment temperature to test the led filament bulbs whether perform properly under those environment. It detects product’s maximum and minimum working enduring temperature whether up to the standard.
d.LED filament bulbs Optic Integrating spherephotoelectricity analysis system.
It is machine to test led filament bulbs Watt, LED filament lamp Luminous Flux, LED bulbs filament CRI, filaments CCT and other details parameters of the light fittings, it shows the quality of your products by this light parameters from Integrating Sphere, We use World famous EverFine Brand Integrating Sphere to test our led lighting products, it shows more accurate in details of technical parameters and ensure it has genuinely meet your request .
