Controller with remote to power up 500 bulbs. The line can be split and you can run two sets of lights up to 250 feet each. Do not run 500 bulbs in a single strand per manufacture recommendation. This can be used as a replacement/additional controller for the 72/100 C9 RGB color changing light bulb kit.
It can also be used as a larger controller for the color changing mini light strands as well which will power up to 70 strands of mini lights. Again, do no run more than 35 strands in series per manufacture recommendation.
