The original specifications are: 6,5 W, 2700 K, 806 lm, efficiency = 124 lm/W, original resistor 34 Ω
The MB10F serves as a full bridge rectifier. It is then followed by a linear current regulator which is the BP5218. If you want to "hack" the lightbulb to make it more durable, reduce it's power dissipation thru the LED's, and reduce it's heat you can change the resistor from 34 Ω to 100 Ω like in the schematic. This modification will reduce the power from 6,5W to 2,4W and reduce the temperature to 55°C Tamb = 21°C. This LED light bulb has 18 LED packages which is great if you want to make an efficient LED light bulb.
