LED Light Bar - Red

sku: COM-09029

Description: The LED Light Bar is a pre-packaged strip of 3 high-output LEDs powered by 12VDC. We don't have specifics on the output luminocity, but take a look at the example GPS Wall Clock project to get an idea. 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 absorbs approximately 30mA @ 12V.

Dimensions:

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

More information about the 12' GPS Wall Clock can be found here.

Are these bright enough to be read outside at a distance, assuming you were to create 7-segment LED’s with these?

I’d say they would be ok to read outside in day light, especially with the Reds. Though it may be a bit hard to read depending on how bright it is outside.

  Actually, the color red is difficult to see out side, which is why there are two red LEDs per pixel inside of large outdoor HD TVs that you see in sports stadiums.
  Green is the easiest to see.

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.
