This is a cute little LED lamp bought from China via ebay. Contrary to the listings 3W rating it is actually rated about half a watt. This is the only LED lamp I've ever seen that uses 5050 LEDs but has all three chips in each LED housing connected in parallel. The lamp has a typical capacitive dropper with smoothing and passes about 33mA through the 5050 LEDs which equates to 11mA per chip.

    Unless you're prepared to condemn every capacitive dropper PSU, maybe find some actual facts to support your conclusions.

    Their CRI (Colour Rendering Index) or in other words quality of light is not as good as a traditional full spectrum tungsten lamp. The warm white are much more pleasant that the cool white, but that's perception is down to where you live. In cold countries we prefer warm white light while in hot countries they prefer cool white light. Not all LED lamps are focussed beams.  This one is quite low level diffused illumination.
