for my client, need to design & develop high quality 9w, 12w, 18w, 22w led bulb with driver on board. So, for that need to design high quality circuit and to do that I need reliable source of datasheet through which I can design high quality led bulb as mentioned above and client wants to give 5 year guarantee for these products so need to design high quality circuit for that and for that I need source for datasheet through which my goal would be achieved. Thanks

 

I suggest you look for BigClive on YouTube. He has taken apart, reverse-engineered and made modifications on many LED bulbs to achieve long operating life.
