LED Light Bar - Blue

Replacement: None. We are no longer carrying this blue LED light bar in our catalog. This page is for reference only.

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 blue 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.

    Are the Blue LED bars as bright as the Green LED bars?... or at least close? Was planning on making a variation of the 12' GPS clock.... more like the 6' temperature display for my lab.

    Could we maybe get some pictures of each of the different colors for these?

    Any idea when these will be available again?

  • 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.

    These are a lot brighter than I thought they were, which is good. Two of these lit up half my room.

    I have 5 of these placed in my pc, lights the entire inside very well! very handy how they can just be hooked into the molex connecter

    I just received the LED bars I ordered and noticed that the blue one was putting out a touch of UV in addition to the blinding blue

    Great product.
    I have a string of these under my kitchen cabinets and my wife is very happy with the result - she even did the wiring for them.
