Mine keeps time ,only 12 or 24 hrs though,think they inbuilt battery?Hey guys and girls I have a question regarding timers
If the power goes off for whatever reason do digital timers still keep track of the current time or do they
stop like the old fashioned manual set ones do??
Haha. That's what I use. I've about 10 of them between my aquariums and garden. The slim feature is great but they are a head fuck to program. They are a reliable unit though.The hpm slimline ones are garbage
i use these aswell, 3+yrs, never missed a beat
I use this one mate and I rate it highly.
Ive got LED's mate No ballast requiredjust use a ballast with a inbuilt digi timer ^_^
