I want low power factor (lpf) type IC driver with matching circular MCPCB with very high lumen per wattages (circular MCPCB aluminium thickness be around 1 to 2 m. M. ). Please quote me best price for actual 5, 9, 12, 15, wattages, initially 5 thousand units of each wattages per month with more than 2 years warranty. It should have several resistors for better wide variation electricity anti surge protection input 85V to 265V, good capacitors, condensers, MOV, very good quality IC and copper wired transformer and others with more than two years warranty for regular supply. The dimensions of IC driver should be of standard type & size but minor variations like 2-4 m. M. This way that way / side, is acceptable, same with the circular MCPCB, standard size is desirable but again minor variations like 1 to 5 m. M. Diameter is also acceptable.

The best IC driver should have both constant current(cc) and also constant voltage(CV) supply.
