Battery Issue, or are you using 100% florescent bulbs?

The ST01C unit runs fine off batteries and the battery will last at least 1+ year - many get up to 3 years. No "powerline" voltage is used - this is not a trickle powered type switch. The battery operates a relay switch. So the timer switch will turn on and off as programmed even if you have no electrical power. And because it is a heavy duty relay, it matters not as to whether the circuit is a 1/2 watt night light, a 1 HP motor or whatever up to 15 amp. Many other switches do use trickle current, but not this one. I am a user that purchased from Amazon and very satisfied. Only thing I'd say is watch the video on youtube to make the programming easy and yes the clocks in these units do gain/loose a few minutes over course of a year.

Try that clear battery sleeve. I haven't used aaa battery's in mine yet. I ordered extra 3.7. them large batteries. For maximum light output

I would make sure those batteries are recommended for the light. I would also make sure they are installed properly. Some batteries are also required to charge a certain amount of time before you can use them. The batteries could be defective. I would take them somewhere like Batteries Plus and have them test the batteries. Hope this helps.

I had the same problem with one of the exterior lights it was controling. Seems like a tiny amount of 'current' was still running through it, even when off.I changed the incandescent bulb to a compact florescent bulb. Now it seems better.

I would like to help out but I still haven't installed mine. But I would think that you could use an LED but not sure about floresent bulbs.

Its probably not the diode or bulb, it's probably the driver or power supply. U probably will have to replace the fixture.

I have used it only for a few hours and so far have had no battery issues. The LED bulbs draw very little current and the batteries should last for quite some time.

I have not had any issue with that. I would say if some of the cells are out then you need to replace the bulb. If you notice it is not doing as before take a break from use and then resume.

I haven't had that issue with mine either. I use mine mainly for edging which puts a greater strain on the battery. My battery will normally last between 30 and 45 minutes and all lights go out. I would definitely call their customer service and ask about it.

I've noticed the same thing. After a short time they are completely off and do not drain the battery. I don't know the reason for sure. My theory, LEDs have a broader amperage operating range and pick up the residual in the system for a short time. Just a theory.

i havent had any problems with them. so im assuming that its not normal, if its just one id change it, but it sounds like your saying all are dimming out. May be an alternative issue, but it could very well be possible that its the cheap lights!?

I am sorry but I have not tried the battery system at all, but have only used the lamp whilst plugged into the mains.

I wouldn't suggest using florescent bulbs for strobes, due to there nature of having to warm up to reach maximum output.

I'm so glad that someone else is having this problem, I thought I was doing something wrong!! I'm not to happy with this because batteries are very pricey!! Sorry I have nothing good to say about the lights:(

Hi, I think our battery lasted almost 18 months with reasonable morning and evening usage - it is the only "light switch" for that room. The battery is a 12V MN21/A23. I just replaced it at "Batteries+Bulbs" which I think used to be called "Batteries Plus". There are several available on Amazon.com including: http://www.amazon.com/Duracell-Security-21-Count-Pack/dp/B00005T3E3/ref=sr_1_3?s=electronics&ie=UTF8&qid=1400428723&sr=1-3&keywords=12v+mn21+a23 I know you asked your question a year ago, so I hope someone else finds this helpful too!

My lamp is mounted on top of a 5' high post at the end of the driveway. It's in full sun all day and puts out plenty of light, probably equivalent to a 60 watt incandescent bulb. Check the solar panels ( I have 4, 1 on each side) to make sure they're clean. If your batteries were installed correctly and shade or other nearby light source is not a factor, you might try turning the switch to "OFF" for a couple of days to let it come to a full charge in the sunlight before turning it back to "ON". I've had the lamp for four months in nothing but sunny weather so can't speak to how cloudy days or shorter daylight hours might affect the quality of illumination. I might look into how to best test the Li-ion batteries once they've fully charged if you have access to a volt meter etc. If you've eliminated all other possible reasons for low light quality other than the batteries themselves, testing them should show that they aren't holding a charge. I hope your lamp's "issues" are resolved soon!

I did. But the touch system (to turn on, brighten and dim) no longer works. I have to plug and unplug to turn on/off and no longer have the dimming feature. I'm not certain that the bulb is the cause.
