    I'm trying to make a small gadget which switches on some strip LED's like the ones below for a child.

    I have bought one pretty cheap on ebay and the specs are as below.
    LED Type: 2835 SMD (Non-Waterproof)
    LED Quantity: 300 leds / 5 Meter or 60 leds / Meter.
    Package: 5 Meters / Reel.
    Size: L500cm (5M) x W1.0cm x T0.25cm.
    Output power: <30W /5 Meter.
    Working Input Voltage: 12VDC.
    Working Current/meter: <0.5A.
    Drive Mode: Contant Voltage.
    Working Temperature: -20° to 50°.
    Cut every 3-led: eligible.
    View angle:120°.
    PCB Background: white
    What I want to do is use just a small strip of this total reel of LED's and I want them to run off a battery like a 9 volt torch type battery.

    I see that they have an input voltage of 12 volts. Is there a way I can run this of the battery like I want to. Basically I just want them to turn on when the child flicks a switch. They will be encased in something.

    I'm just not sure how to go about using these. Any hints? Thanks

    At 9v it might light up, but no where as bright as 12v
