I purchased this kit off a seller on Ebay, but I don't have the time/inclination to put it together. It is very well thought out with lots of pictures in the instruction manual.
Kit comes with: soldering iron & stand, solder, power supply, wire, 5 leds in the 465-470nm wavelength, & resistors.
Even if you've never soldered before, the instructions show you how.
I did also buy a new 4 foot 1 1/2" wide board (home depot) that I was going to mount these leds to. I will sell that along with the kit.
Everything is new.
