i want to attach this to the bottom of my longboard, do i need to keep the leds plugged in to a power source to keep working?

Yes, Ive actually done this myself. You can either pick up an 8 AAA or AA battery holder and hook the lights directly up to that (might want to put the battery case in a plastic bag so they dont get wet, mine did) or to save space you can hook up 2 9V batteries to a voltage regulator circuit which you can make for cheap with parts from radioshack. I did the thing with 2 9V and it was small enough to fit in one of those tiny project boxes which i then bolted directly to the bottom of my board.

If you connect it to a 12V battery it should work fine (no need to plug it into an outlet). The whole strip needs 5 Amps or 60 Watts to work properly. If you cut the strip short you can use a smaller battery. A battery pack of 8 alkaline batteries (AA, C, or D) will work also.

I want to use on my daughters cheerleading box. What kind of power supply should I buy?

A power source to run these? Of course not. These run off of Fairy Dust, and luckily they are pre-loaded with a lifetime supply so the lights never turn off. Who needs electricity to run lights?

I did this for my bike, Took 2 9 V batteries and strapped them on. I modified the wires so that they correspond with the batteries

Your longboard? If this is a skateboard, you'll be OK with a 12V battery. If a surfboard, forget it. When this says waterproof, it means "IP65 Waterproof" - you can spray it with a mister, but not submerge it. See some of the other reviews in this regard.

Yes, they need power to work, but they are dc voltage so you could rig up a power supply on the board

I'm not too sure what you mean by let it stay lit. With this setup you would probably be better off using a speed light and they ll will go off as you trigger them.

No. A strobe power supply supplies high voltage. These LED modules should be connected to a switched 12 volt source.

Just plug it in the balance port on your battery. Mounting it, I used the velcro provided and drilled two small holes slightly off center and close together, mark one of the wires and the terminal block un-plug them from the block feed through the holes and Bingo. Mine came out very nice. Also cut out a small rectangle on the velcro on the light to make a nice fit for the wires on the light itself..

I'm very happy with my fixture. The quality is fine and I have had no issues. How can you mount anything if the power source is coming from the TOP?Wouldn't the source need to come from the BOTTOM of the beam?

Yes. Although you may want to overestimate your requirements for that power supply. These boards are quite efficient, but not 100%, so your supply will need to provide &gt;30 watts to get 30 watts to the LED. Anyway, in all cases it is a good idea to have 30% or so overhead on your power supply.

They work pretty good and probably fine for something like that. You would need a few of them though. I might suggest the high intensity bullet led lights which i put on my boat instead. A bit pricier, but you could put one in the bottom and it would do the trick.

if your amp has a 12v power supply you should be able to wire it into the amps wiring Just be sure to check the amps on the power supply iotherwise you will have to run a separate cord for just the led's but yes the tape on the back of the lights should hold but for long term i suggest screwing it in with mounting brackets * Do Not Screw threw the Light cord*

The connectors are not waterproof. In fact the way the pin connectors on the LED strings are made, the pins could not be made waterproof. You could use this outdoors, and I have, by wrapping the connections with waterproof tape or a dab of silicon after plugging them together. I would not try this in a submerged location. It will be weather resistant, not waterproof

Assuming you mean you have an AC adapter that outputs 12v DC, you'll probably burn out the led without putting a resistor in the mix. LEDs typically only need a few volts to light

Why would you need to? Its a repeater. Your first power source should be enough for the first LED strip, after each strip you install a repeater.

My display stays lit, too. If the needed connector isn't included, why would you keep it?

Certainly sounds like you wired it correctly. Just remember that LEDs are polarity sensitive, so make sure your positive is on the red wire. If that is confirmed, then I have nothing more to suggest.

This is just an LED strip with a +/- lead on it. You should probably wire through a fused circuit that gets power when you want it to. Some 12V accessories have power all of the time, some with key, etc... I have mine wired through the interior lights circuit so they come on with them. I made sure it was a fused circuit because I had one of these short out and melt wires.

It came with a corded led status wizard you can mount anywhere. Check the manual at PD.

These LED lights come with a small plastic bracket that you can use two way tape or screws. I was suggest screws, but may need to use a self tapping screw or a pilot hole.

The package I received only had the LEDs. Each LED has about a one inch lead on it, so you'll need to find a way to secure them to the battery (probably at least a 9v). If you have a little soldering experience, it's pretty simple to attach a bit of wire. Don't forget the polarity. The flat side of the base of the LED indicates the negative polarity.
