This mains powered LED strip (220V) had an interesting surprise in the form of colour temperature selection between cold white, white and warm white.

    That switching chip might be a Bright Power S4225MB "Wall Switch Dimmer", switching A to B to (A+B)/2.

    I can think of a few uses for these strips. They look very interesting.

    You could turn it on at least once to show how it works.

    is a tear-down of a robotic sex doll in the future?

    The led driver appears to be a 2 bit latched binary counter, the resistor and capacitor are probably connected to the clock input, the capacitor in this case would be to prevent bounce.

    Clive, Im looking into making something similar to this but with 60 x 3w LEDS with few diffent colours ranges for an aquarium. How do I work out the power supply and what resisters to use?

    Same as common down lights.

    I just ordered one of these on eBay today (but from a cheaper supplier in China. I find that stuff from Singapore takes ages to get to Australia while the stuff from China will get here in about 2 weeks if it's shipped via airmail). I've been replacing all my lights with LED versions when I remembered the light in the range hood/exhaust. It's a 40 W tungsten bulb with an E14 socket.
    At first, I bought some LED COB lights (3 W and 3.5 W, I think) then I remembered this vid. I measured the space and should take this 40 cm light easily. At 13 W it should provide a lot more illumination plus the colour temp change would be interesting (it should also mean that the wattage should be halved when not using both colour temp sets) while using less than the existing bulb.

    Is there a video which shows the set-up of Clive’s bench? I’m intrigued as to how he both has the lighting/camera setup and what else he has in the workshop.
