I was nervous when choosing from the many options for a transformer. The 120W model was oversized for my use, but the smaller one had fewer options for setting the time. This product seems well constructed and is easy to install. I ran two 14 gauge wires connected to ten 2.3W deck lights and may extend in the future. With everything turned on the unit is drawing only ~30W @ 120V (think small incandescent bulb they used to install in refrigerators). The total run of wiring is only about 75 feet.

The timer control is well thought out and offers various options. The best selection (for me) turns on the lights at dusk and then shuts off at a specified time. Customers who need the lights for security purposes may want to leave them on all night, but ours are decorative and it didn't make sense to have them running at 3am in the morning.

I've found that the best way to significantly extend the lifespan of outdoor electrical devices (especially those that plug in) is to not put them outdoors. So I ran a new 15A circuit to a CGFI outlet in my garage where I mounted the transformer. I cut a hole in the drywall behind the unit (near the bottom) and threaded the low voltage wire behind the drywall and out to our courtyard about 4 inches above the ground. I then drilled a 3/8" hole and poked the sensor through the wall (second photo) and secured it with silicone sealer so it's almost invisible. To enhance the beauty of my garage (ha-ha) I masked the vents on the bottom of the unit and spray painted the outside of the box white. The one thing I wish they offered was a transformer with an internal GFI device so one could mount the transformer directly to a device box and lose the damn plug.

If you do mount this outside, make sure it's plugged into a CGFI outlet that's covered by a water resistant box. The low-voltage lights and wiring are more forgiving, but the transformer itself is pulling over an amp of 120V power from your electrical system and shouldn't be installed like Clark Griswold in the movie Christmas Vacation. : - )

I've been using this every day, indoors for about 2 months now. Haven't had a single issue with it. I can't comment on the light sensor since being inside I rely on the timer function that works very well. It even keeps time through power outages. It just feels like a solid build and the switch and buttons feel robust.

I'm using this for ~300 feet of 14 gauge wire running 56 watts of lights. Only 80% of the total power of any transformer should be used, so at 96 watts that gives me plenty of room for resistance draw caused by the length of the wire.

One thing I wish is that it had clamp style connectors as opposed to screws. Holding the unit while trying to screw in a wire to the terminals is difficult without having something to rest it on. Attaching multiple wires is next to impossible unless you have some loop terminals.

Very easy to set up and it works great. Bought this to replace an old one. Would defiantly recommend.

Bought this to replace an old (18 years) timer that stopped working. This has worked perfectly. In use for a few months with no issues. Recommended.

At the root of just about every electronic purchase on line is the question of "if I have a problem, I wonder how well customer sevice will address my issue." Let me tell you this: I have now been absolutely blown away by the Goodsman customer service team. My first phone call to them made me feel like I was their most important customer and their goal was my satisfaction with their products.

I purchased 2 120 watt power packs to address my landscaping lighting needs. I promptly received them and hooked up my lights. Instalation was a snap, directions and programming as easy. Great product! But, not long afterwards the photo sensor / timer stopped working on one unit. A quick call to Amazon and a replacement unit was here the next day. Not bad, no fuss, no issues and as I hoped it would be from Amazon customer service.

Well, 8 months later the replacement Goodsman sent me stopped working. I dreaded calling their customer service number figuring I would have an issue getting satisfaction from them since this was a second replacement request.

I was amazed at how well my call was received! Goodsman did the purchase verification and called me back the THE NEXT DAY! He arranged for return shipping and explained they would do diagnostics on the unit and let me know. Fair enough and understandable. In the same conversation I informed the Goodsman Customer rep of a slight issue on the other unit's door hinge. The first words out of the rep were "that's not what we want for our customers, send it back to us as well." What? Are you kidding? Not what I was asking Goodsman to do... but, ok! The rep told me it would be a few days once they received the units to evaluate and he would give me a call. Ok, I admit I was feeling pretty good at this point about how Goodsman's rep was treating me; but call me back in a few days? Come on who does that anymore? Real customer service is hard to find.

You could have blown me over with a feather when Goodsman's rep called me this morning! I return mailed the units on a Tuesday and received Goodsman's call on the following Wednesday with a holiday Monday in between. Stunning customer service!

I was informed BOTH units would replaced and would be in the mail today! The Goodsman rep made it very clear my satisfaction was his goal and part of their company culture.

For me customer service is a big piece in my decision making process when I read reviews. Goodsman nailed it! I Highly recommend them because they stand behind their product and know how to deliver excellent customer service.

The only thing I can say now is I wish I had bought my landscaping lights from them as well!
