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, the BP5218 as a linear current regulator. If you want to "hack" the lightbulb to make it more durable, reduce it's power dissipation thru the LED's, 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.
