Ordered this package of warm white LED's, not for a brick build, but for a wooden book nook kit. With the book nook kit one builds a pair of bookends. One side is a steam engine coming out of tunnel and the other book end is a passenger cr going into the tunnel.I am still in the process of building the bookends. What I am doing is adding this warm white LED light into the bookends build.The passenger car will be lit on the inside, the steam engines conductor cabin, and the headlight on the front of the engine will light up.This will add an amazing level of detail and customization to this build.These LED's are beautiful and wow are they ever bright! I love the fact that it uses a USB plug for power instead of batteries.Overall this is a thoroughly complete set that is well made and well worth the asking price.
