| the pet store timers are really cool because they switch between day and night, they're not just straight timers. You can plug your day lights into the day side, and the moon lights into the night side, and the timer will switch between them at the specified intervals. You may be able to find something similar online for cheaper.
(also useful for reptile owners who need to switch between lights and heaters at night.)
The Intermatic timers are very nice, though they're only on/off (so you need two timers for the two light cycles). you can get a two pack for $7...but the 3-pin units are a little more expensive. |
