## Description

DEWENWILS 30W Outdoor Low Voltage Transformer with Timer and Photocell Light Sensor, 12V DC, ETL Listed - desertcart.com

Review: No more adjusting a timer - I have had low voltage landscape lighting for many years, and upgraded to a dusk to dawn transformer for the lights in the front and side of the house. The rear yard was still on a mechanical timer and I had to change the timer at every season change. Now, no more changing anything and it comes on when it starts to get dark and goes off at sunrise. It was simple to set up and seems to work well.
Review: Works great - This timer is easy to use, and it works fantastic for low voltage 12 volt outdoor LED lighting but after buying it we decided that solar lights were the way to go. Easier to work with and long lasting too.

## Questions & Answers

**Q: Can I set this to "always on" and then use it with an external timer?**
A: Yes, of course. This low voltage transformer has memory function, it remains the timer mode you selected before. So you can set it "Always on" and use it with an external timer. Any more problem, please feel free to contact us via Support@dewenwils.com

**Q: Will turning on a light near the transformer make the transformer turn off? What if it’s in timer mode? Will it turn off mid timer if light is sensed?**
A: Yes, the sensor will detect the light and make the transformer turn off. If it's in timer mode, it will turns off once light is sensed.

**Q: Will this work with a better homes and garden quick fit lighting kit?**
A: Hello,

If your lighting kit is (1) LED lights, not halogen; (2) 12V working voltage, (3)the total wattage of your lights don't exceed 48Watt(60*0.8), then you can use it. Hope this helps you. If you have any problem, please feel free to contact us via support@dewenwils.com.

**Q: My son keeps getting the error light. He has only hooked up 3 lights so far so not over and not short circuit. Ideas?**
A: The error light comes on when something is shorted out. Check each fixture, each wire, each bulb for continuity. You have to do a process of elimination to find the cause.
