    you need to convert AC (220v) to DC (approx. 12v)

    Gamay ra ang power need ang LED, plugging it in directly without any converters or transformers will burn out your LED instantly.

    Especially with an AC source..

    pwede mana imong gusto TS nga direct nimo sa 220v ang imong mga led using resistor. 16kohms for each LED is enough to reduce current aron d maguba.

    Pero kung imo ning buhaton para maka save ka kurynte ayaw nlng padayon kai d jud ka maka save ana mo dako pa imong kuryente. mas dako pa ang power nga ma convert to heat kai sa magamit sa imong LED..

    Pangita nlng ug charger sa cellphone maoy gamita.

    pila pud ka wattage bro para sa 16k? 1w? or kaya ang 1/2w?

    TS, unsa pud config sa imung mga LED? Series? or Parallel?

    1/2 is enough

    LED has a polarity.....it needs DC source..
