An led must be connected in a circuit the right way around observe the polarity of the led. It is completely filled with a resin. The reference circuit for the microchip cl8800 is close to the circuit found on the 3m led bulb though the 3m bulb includes an additional rc network not shown here for phase dimming. A comparable 8 watts costs 7 usd in their website so i think i got a good deal.
Schematic diagram of the 12w led light bulb the heart of the circuit is a pt4554d high precision non isolated step down led constant current ic. It reveals the components of the circuit as streamlined shapes and also the power as well as signal connections between the devices. The following image shows the pcb layout of the led light bulb.
