If you have LED lighting, it is best not to look for Philips to find the same source of goods, because Philips' foundry catches a lot, and many small workshops are also helping to do OEM work. If you encounter these, it is easy to have quality problems.
You can talk to the OEM of OSRAM Lighting or GE Lighting. The OEM manufacturers of OSRAM lighting LED lighting in Chinese mainland include Yufu and Huilida in Taiwan Province, private Punai Optoelectronics and Shaoxing's own Xinhe. GE Lighting has no LED lighting foundry in Chinese mainland for the time being, but it is said that Punai Optoelectronics has negotiated with GE in the United States to be an LED lighting foundry for GE.
If it were not LED lighting, but traditional lights, it wouldn't take so much effort. You just need to find some agents selling traditional lamps to set the price.
