Rated 4.0 out of 5 by 43 reviewers.
Rated 5.0 out of 5.0 by the little box Easy to install. I wanted to run spot lights on my palm trees at night and this low voltage system allowed me to run two lights (20 watts each). Really sets off my palm trees. It is easy to install. Had to purchase more wire to run through the yard but not a big deal. I would definitely recommend this product. I actually had one already and purchased this one because the other one I bought a couple of years ago has worked so well. Good product! April 14, 2015
Rated 5.0 out of 5.0 by Lights Great product quality and easy to install. Looks great! April 14, 2015
Rated 5.0 out of 5.0 by Good size & features I mounted the photo cell above the fence to keep it above the snow October 29, 2013
Rated 5.0 out of 5.0 by Landscape lights made easy This unit is easy to install and the operating instructions are understandable. I ran the wire, hooked it up to the transformer, attached lights where I wanted them, plugged in and it worked like a champ. February 18, 2015
Rated 5.0 out of 5.0 by It does it's job. I bought this to replace the power source with my LED Landscape Lights kit. I wanted to put more lights and needed the extra power. It is very convenient that the photocell detects the sunset and it is easy to program. February 11, 2015
Rated 1.0 out of 5.0 by Malibu needs to change instructions for Consumers!! I have worked in landscaping as well as electrical. After researching and talking with heads of department at Home depot Fargo ND, I chosse to use malibu lighting at my home. The only way that I would reccomend this product "especially" to the Do it yourselfers is to change the advertising on box. It needs to read on the 45 watt transformer "MAXIMUM DISTANCE AT 100 FEET". oN THE 120 WATT-MAXIMUM DISTNACE AT 125 FEET. After installing and having my lights not work properly, I called Malibu and they directed me to their website after they informed me the box should not have the instructions of # of lights x watt....then take that total watts x distnace=what size wire to use.?? Also on their website ONLY they have a simple diagram to show you DO NOT use 12 gauge or 14 gauge wire on a 45 watt, to get 125 feet on my 120 watt you have to use 12 gauge wire-would have been good to know. I had to buy (2) 120 Watt Transformers and change out cable to 2 runs at 125 feet and the lights work great! The problem is not the product, but lack of directions as it is marketed. August 26, 2014
Rated 5.0 out of 5.0 by A much needed upgrade This was a much needed replacement for my old control box that I bought when I replaced my old filament fixtures with LEDs. The light sensor is on a wire making it easier to adjust when the lights switch on/off at dusk/dawn. Now my old high wattage lights aren't still on at 10:00. Also the control options are lighted words (not abbreviations) so you can see them at night, and are controlled by a rotary switch instead of push button advance system. Appearance isn't stylish but is unobtrusive. LED is definitely the way to go. March 11, 2014
Rated 4.0 out of 5.0 by good transformer purchased this transformer as a replacement for one that stopped working. It not only has a daylight sensor, but an option to set a timer OR dust to dawn. Easy to install. Easy to program. January 10, 2012
