Fine timer but no photo cell


I'm looking for a photo cell actuated digital timer that will go ON at Dawn and OFF at dusk carrying a moderate fractional hp 120V AC load.

Everything on the market seems to be OFF at Dawn and ON at Dusk ....

Can anyone steer me to a commercial product?
This thread is from 2007. Are you asking the same question as the original poster? If so, it's been fairly well answered above: use a normal dusk-dawn control with a relay. If not... the OP's long gone by now.

Not JUST an 'outdoor' timer needed


The need is for a photo cell activated timer that operates

ON at Dawn and OFF at Dusk ...

Simple enought NO? But believe it or NOT I haven't found one with this capability. ..
one that photo cell activated that will turn ON at first light and OFF in the evening ...

I've found many with all kinds of bells and whistles geared to Night and LOW LIGHT actuation with various shut off options but nothing with the ON at Dawn feature and OFF at Dusk.

Surely there're fountains and other daylight displays, security cameras, etc. that are ONLY USED during DAYLIGHT hours.

I just haven't been able to find any commerical units.. I've Googled and Bing'd " ON at Dawn and OFF at Dusk" timer and haven't found ANY!

I must be missing something.... If you simply use a timer, why can't you set it to come ON at 8 am and go OFF at 8pm ( or whatever)

RE: Regular OUTDOOR Timer


That's what I have been doing. I was hoping for a commercial unit that I could plug in and forget and yet be tied changing daylight hours only including daylight savings time.

And I'd agree too that I'm not willing to shell out big $$$$ for a do all/end all commercial unit, IF I could find one.

What's surprised me is that there apparently aren't any available.

I'd think the market for these would be so small it's not worthwhile. Business customers would be the biggest market (i'm guessing) and they'd probably just set a timer that corresponds to their business hours. I really can't think of any examples where this would be a common need. People that use fountains and " daylight displays" would probably light them up at night with a standard photo switch. security cameras would use IR at night, and they switch over automatically

I don't disagree


The market would be small. But what would it take with micro controlled controlled unit to add the feature.

Anyway ... I'll let you know if I turn anything up.
Be sure of that.

Well...there's always X10 technology. It works for me on most of my lighting needs. You already have the expensive part (the computer). It is 99% reliable, and gives you ultimate flexibility. I've been using it for 12 years now with little problem.

Did you ever find something off-the-shelf? I did a similar search and the 2 leading candidates (other than a DIY photocell/relay circuit) are

1) conventional dusk-to-dawn power strip that has an accessible or replace-able internal SPDT relay re-wired to use the opposite throw. But I'd prefer not to fool with wiring, soldering, etc.

2) $1 night-lite affixed over photocell of conventional $15-20 dusk-to-dawn garden power-strip that reverses logic. Night-lite comes on at dusk which turns off the power-strip, night-lite turns off at dawn which turns on the power-strip. Conceptually simple, but not so practical and somewhat unsightly! When night-lite bulb fails, strip comes on forever.

Mine is an indoor application and I'm thinking $20 for a light-activated power strip w/ at least 3 AC outlets - not actually a "dawn-to-dusk" application per se.

Nice Idea ...


I'm going to give it try. Keep my eye out for one of those dust-to-dawn power strips. And I have a bunch of those night-activated night lites.
