that's in the same isle in home depot as the clamp lights.... and very close to that you can find the timers, i got a mechanical one for 12 bucks and it's the shit... only deviates a couple of minutes, not too bad... if you're getting a mechanical timer, dnt get the 5 dollar one, that one can deviate almost 20 mins... i had to return mine and get the bigger one, which works great...
