Benefits: pre-soldered so you don’t have to add wires or deal with soldering

Benefits: students can learn to solder, distance between lights can be any distance desired, lights are small
Constraints: soldering wires between each light takes a lot of time

Also recommended to have a TA help with soldering and/or a few students you trust do this for most of the class.
