    I am wanting to run two of these on a diy led fixture and will have them mounted to a heatsink, I cant figure out what type of powersupply I need to get for them since they are rates at 12V, .15A? I was looking at rapid led 1 powersupply rated at .3A and just using it to run both of them running a y 3 pin, is this to much power or not enough?

    FWIW, power supplies are generally "passive"; IOW, they allow a device to draw what it needs, and their ratings are max output. OTOH, using a .3A supply with 2- .15A devices will max out the supply continuously, which can cause heat issues with the supply unit and devices. You would be better to go with a .5A power supply.
