I like the aluminium housings of these lamps, they're very stylish and quite nicely engineered. Even if the electrical isolation inside isn't quite up to scratch. The three LEDs are mounted on an aluminium core PCB that is held in place by a rather ornate light guide which is then held in place with the outer cover, which presses the whole lot down onto the aluminium body to ensure good heatsinking. When I got this particular lamp the light guide was squint inside and it's very hard to reassemble it without it ending up at an angle. This doesn't bode too well for light and heat transfer. In the base is a very common switchmode power supply specifically designed for 3W lamps, that uses a common BP9021 style chip made by BP Semi. These are a newer generation chip that is dedicated to driving small transformers and providing primary side regulation via current sensing. The circuit has a very low component count. However... A single wrap of winding tape isn't really good enough insulation between a pointy solder connection and a hot aluminium housing!
