I also ordered this kit when I bought the Pendulum, so it was built the same night. It works far past my expectations. On about two hours of sunlight, and the rest overcast it gets enough charge to go all night. It came with two orange and two green lights. I used these for awhile but then replaced one orange and one green with a red and a blue. The blue requires a bit more power, so sometimes I wake up with it slightly dimmer than the others. It is the brightest light when it gets a good charge. Most of the times, it lasts all night without even any decrease in its output amount. Astonishing is all I can say.
