I under stand it has a timer of 1-9 hours is that only based on the photocell? or can it be based on a timer? Photocell might not work well in my loca

I am pretty sure it is based on the photo cell, because their are no clock settings. I just use mine in auto, on and off with the sun.

There is a photo cell setting and a time setting the photo cell setting ar between 1 and 9 hours I believe. Much much better built than the Malibu. .

The timer sets the off time (1-9hrs) after the photocell turn it on. My two work just fine with a start time seemingly after it gets fairly dark, not just dusk. If you have a night lighting issue you could consider putting a small shield on the door where the photocell is located so it will only see daylight. I have one located about 4 ft below a light and it does not bother the unit when the light is turned on, no mod necessary. Good product at a good price.

Mine has a timer (D10), but it is not marked with hours on our model. I calibrated it, and put the hours next to the marks. It works great, but the time needed does depend on what you are drying.

Any timer would work fine with the light. Hydro farm sells a 7 day digital one that you can have different settings throughout the week but even a cheap analog timer from Walmart would work fine with it

No , it comes on by photocell . You can only program the number of hours of lighting....not different stations.

This timer is only rated for a 12 volt DC circuit. If the photo cell is in a 12VDC circuit this timer could work by actuating the photo cell on a schedule. There are timers with photocells that do work in 120 VAC circuit. CONNECTING THIS DEVICE TO A 120 VOLT ALTERNATING CURRENT WOULD BE A FIRE HAZARD.

Honestly, the one that I got didn't work AT ALL, self timer or no. I'm sure it would work with a self-timer if it actually DID work.

I have been setting my timer to 9 hours, and that seems to work well. You can control the timing. If you think 9 hours is too long, set for less.

This particular timer does not go by days (it does let you set it to go on every 24, 48, or 72 hours though). I think it's strength lies in the minutes you set it for and every hour if you want. I use it for misters for that very reason. I'm thinking a different timer might be your best bet here.

Yes, this will work with a timer (any LED light with a regular plug should work with a timer). I haven't used it with a refugium, but any light that allows plant/algae growth should work fine. I'd say go with this one, it'll be enough.

I've used mine for 6 straight months (24 hrs/day) last year wintering plants here in Alaska. This year it's been on 16 hours a day using a timer since October. I use one of those flexible table lights you could by at any store. I would look at some of the suggestions mentioned in earlier comments for possible light failure.

This timer does not have the ability to detect changes in light. This would require using a photocell in the circuit.

I'm not sure, Xela. Is the light working ? Use common sense. Charge when it gets weaker. I think a 4 hr charge every month should do the trick, as long as you don't use it constantly on full power. My light fell off a ladder and broke. I fixed it but the charging light had to be disabled. Maybe try another respondent ?...C

Once the Timer is set, it stays lighted for 6 hours....... then off for 18 hours. I bought 5 and I love them. I've used them on decorative wreaths on my front door and on house plants to add sparkle.

Nope - the photo cell is in the unit. We actually have kind of problem in that we put the box where our neighbor's motion security light is - so if that comes on, our lights go out, and the lights get reset to the time. Other than that - it's really good. We did find though, that the bulbs that come with the lights we ordered tend to fail pretty quickly - but the replacement bulbs last longer.

I let mine go for 12 hrs.the unit does not have a timer on it,you must add a timer or track time when you start.

I have the light on a timer and it is on about 4hrs per day. My bird loves it and sits right under it.

Regardless of what the other users say, the Timer DOES NOT use any power from the circuit as only the "hot leg" in the circuit is wired (no "neutral" white wire required or wired). The Timer uses an internal relay which performs the ON and OFF switching and operates entirely from the battery. But this internal relay (and also the clock function) uses very little current and therefore the battery should last for at least a year or two depending on how many on/off sequences you have programmed. I have four of these timers which I have been using in the "Astro" mode (automatically changes sunrise and sunset times) since last July (2014) and they have been performing flawlessly.
