LED Light Bar - Green

Want to make a 12 ft GPS wall clock? This is the perfect item to light it up! Even if you that's not the project you are looking to build, these light bars pack quite a bit of light into three small LED's and they are very easy to set up with no soldering required.

The green LED Light Bar is a pre-packaged strip of 3 high-output LEDs powered by 12VDC. Each unit comes with a fully assembled and tested PCB with current limiting resistors, a wall-mount holder, and a polarized connection cable. Each LED Light Bar only absorbs approximately 30mA @ 12V.

  • 3.08x 0.59" (78x15mm)
  • Mounting hole OD is 0.176" (4.5mm)

LED Light Bar Hookup

September 24, 2013

A quick overview of SparkFun's LED light bars, and some examples to show how to hook them up.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Is there a datasheet for these LEDs anywhere? I really would like to be able to mount these on an illuminated panel I'm working on but I need to know the height of the LEDs.

    These things would be perfect for the illuminated panels in a home cockpit I'm working on, get them back in stock! :D

  • I bought a few of these recently, and although they say 30mA @ 12V, if you remove the limiting resistor, these will easily run off the 5V that an Arduino outputs. I eventually ended up de-soldering the LEDs, but they work fine in the module. These are definately very bright, even at 5V, but they are only very bright looking straight at them from the front, whereas from the sides they are less bright. Just as a note, the wall mounting clips have double sided adhesive on the back of them, although you cannot see this from the picture. Mine came with white leads, and unlike the description, the leads and the sockets are not polarised such that the modules cannot be wired in reverse. Linking these things together in chains does not decrease the brightness at all,so there is no need to link them all individually to a power source.

    Can anyone give me a link to where, if anywhere, the individual LED's that are used on this module are sold?
    I am making a 4' long minature of the 12' long GPS Wall Clock(I have limited wall space!), and I need a LED for my colons that matches the segments both in color and intensity. Unfortuantly, I can't fit one of these modules inside af a colon.

    Are you guys out of these for good? or is demand just extreme for the clock?

    • N8B / about 13 years ago / 1

      They haven't been retired and I can't tell when they will be back in stock. Probably not for a couple months.
