Typical store bought controllers are garbage…. And professional ones are expensive… so I made my own.

Seen here: a bank of relays and an Arduino

Close up of the relays, this board can be purchased on amazon for around $20, I got mine at a local store called vetco, link here:

Close up of Arduino and RTC module, they can both be purchased on amazon, or at vetco

Overview of the entire device, please note that due to the amount of plugs I used, if every one were to be used I would recommend switching to 240 V instead of 110V. When using 240 you can use 1 leg for half the light and the other for the rest, this will ensure you do not over tax the breaker. Please keep in mind that I used a WatStop to verify I was not pulling to many amps with this system.



Below is a link to a zip files containing all the code I have to the light, please not he code is rough and does need refinement, this code is open source, so use it however you wish.
