Anyone heard of a "Dawk to Dusk" light timer?

I have 3 timers
MH timer
Actinic timer
Night light timer

I got them from Canadian Tire, on sale for $15 each. They are a Garrison exterior timer with a digital display, 10 on/off settings, and rechargable battery back-up, which is nice when the power goes out because you don't have to reprogram
