heres how its done basicly;
solder a wire to +(says 12v) and another one to – part of led strip. Then get a extra molex with wires on it. Cut the yellow and black wires in half and solder the + wire to yellow wire of molex and other one to black wire of molex.plug the molex to one of your – psu ‘s molex connector.

‘Lo He is probably talking about using your strips to light up the inside of a computer, computers run on DC and have molex connectors inside, they are 5v/12v so you could just get an extender and solder you connector onto it. =)

Or was it the 3528’s at the same per foot? I will be dealing with this size.


steelboned May 1, 2013 at 1:30 pm

So the 5050’s at 10 per foot consume that wattage?

What’s the name of the song? I like it 🙂

Yeah that would work! But for a more secure connection, you could also use one of our strip light connectors: strip to dc plug for a plug-in 12V adapter, or strip to splice connector, which gives you a positive and negative wire that can either be soldered or secured using wire nuts.

Hi, how would I run these from a 12v source. Would I be able to simply solder wires onto the solder points and connect up, or would I have to use a driver circuit?

i bought strip led on this site ledmasterltd com

I like the music!

That could be problematic. When you do continual long runs (like over 5 meters) you could run into the issue of voltage drop. Also, check the power usage of your strip and the wattage limit on your power supplies and controllers as they will likely be maxed out at around 60W. Check out another video we made about Large Installations–it will likely answer a lot of your questions.

Hi. Can you make it taller for example 10 meters and use 1 IR remote controller?


elementalLED May 1, 2013 at 6:28 pm

We don’t know of a way to connect this strip to a computer. You would need to connect the strip to a DC plug connector and then find a connector with a 12V DC jack on one end and a USB connector on the other. Let us know if you find such a device.

This strip consumes 1.44 watts per foot. So, one meter would consume 4.72 watts.

For this strip, the cut points are at 3 LED intervals. You may want to look for an LED module with just one chip instead of strip light for your purposes.

can i connect these to my computer?? can i somehow attach this to my powersupply?


varun jadhav May 1, 2013 at 8:20 pm

Since when AC supply have polarity?


Jack Watts May 1, 2013 at 8:33 pm

InStyle LED has some great videos check them out


Martin Wood May 1, 2013 at 8:41 pm

I need to use just 1 LED, can I cut the strip to just one LED or do I have to stick to the 3 LED sections?


Tarush Lall May 1, 2013 at 9:16 pm

hi, can u tel me the electricity consumption of a led strip (for a meter length)!


monimoni0147 May 1, 2013 at 10:05 pm

for some reason i feel like the video was too long for the amount of information in it…


megaledlighting May 1, 2013 at 10:11 pm

Nice video ElementalLED!

Just one observation you may want to change:
AC power shown on your schematic visual should not really be shown
as “+ – ” (it is AC = alternating current) we would usually show it as
“L N” (live, neutral)

very cheap


Jimbo Jett May 1, 2013 at 11:15 pm

Thanks, but don’t worry about the legalities in each of the 50 states. My plan is to use it IN ADDITION to my car’s current/OEM turn signals. I see many pick-up trucks lately with an added LED light bar attached at the bottom of the tailgate (plus normal tail-lights). Kind of like the 3rd/high mounted stop-light in all new cars.  Anyway, I like the idea and want something similar for my car, but I would like the amber LED strip to sequence. Thanks.

Please check our project: myledlamp(dot)net it’s a lighting system controlled by android through bluetooth, without the need of a router.
