Penel Optoelectronics Technology Co.,Ltd

It's testing IES (light distribution) of the led light . The test must be in a professional dark room ,with the device “light-distribution photometer” . Such a dark room costs about 45,000 USD.  With it we can test our led fixtures freely , to generate the IES test report, then we can use Dialux software to simulate the lighting effect of all application, to check the luminance , uniformity, and glare , so work out the best lighting solution for customers.
LED sports lights are used outdoor so the reliable waterproof is very important . A IP66 structure housing is not enough , must plus the very serious seal technology during production. We use glue machine to put the silicon glue before and after putting the seal-ring of the lens , so the seal around lens can be really reliable and water won't go into from there . Some customers may don't like this way because they want to change different beam angle lens freely by themselves , but , trust me , not sealing well the lens will bring customer complaints sooner or later .
As a modern factory we have many advanced devices , like this "Air leak tester" , to test if the led light has good seal , so can make sure reliable waterproof . For outdoor lights , waterproof is very important.
The test principle is : input some air into the product from the hole for breather valve, then test the air pressure inside the product .
Now 100% of our product need pass this test before being shipped to customers.
Reliable waterproof is very important for outdoor lights.  From product structure design ,to good sealing technology during production , to full testing for each order,  the complete quality management system is the key to make sure.
