My new LED tombstone lights

A few years ago I made LED spotlights out of the little finger LED toys and having them connect up to a USB hub. I had gotten the idea from a thread started here. For some reason even though I used the same power supply and resistors for all of them they did not have the same uniform brightness. Some were great, some were just barely passable, and some were just plain horrible. I always seem to put lighting on hold to work other projects even though I know how important it is. Earlier this year I got introduced to 12V LED strips. I love these things. Bright, uniform, and relatively cheap - my kind of combo. I've made about 12 so far with 20 more to go. I mounted them to wood that I made from ripping a 2x4 at 45 degree angle several times. The adhesive tape on the back of the strips are useless and I ended up hot gluing them to wood. To connect them to themselves and the power supply I used JST male/female connectors made for RC planes. I got a set of 20 for about $10 form Amazon. I also got the 60W 12V power supply from Amazon. I have three female connectors coming off of the power supply and I also made a few splitters that can be placed anywhere along the chain of lights if need be. Here is a comparison of the lights to my old spot lights. The cross tombstone has the LED strip while the others have the old spots. Sorry for the bad picture but you can see the difference.

Those look amazing! I'd like to know where to get some of those.

Thanks for the pics!
I got mine from Amazon. Make sure to get the waterproof ones. They come in several color options. The green and purple seem to be the best for lighting something up that needs to be read. Here's a link to the ones I got. http://www.amazon.com/gp/product/B00EKEODA0/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1
Love it. What kind of wire did you use to distribute power to each strip? Looks like CAT5/CAT6 to me. If so, how many pairs did you use to transmit power?
