What is inside an Asda LED mains light bulb?

I have looked at the own brand LED light bulbs on sale in the major supermarkets and wondered what their construction quality was like. Therefore I was interested to come across the video below from BigClive showing the teardown of an ASDA own brand Edison Screw 4W LED light bulb. The construction quality seems reasonable and the code on the chip suggests it might have been made for ASDA by TCP? TCP branded lamps are sold by stores such as Homebase.
