Could have been better… Like others have stated with these type of lights and systems, is you get what you pay for. Don’t get me wrong, they are not horrid, but by no means are they a great system. The problem with Moonrays is the connection. It is made at the light bulb base where there are two pins under the base that pierce the cable. The problems are: The cable that comes with this unit is a very small gauge (18 Gauge is what is supplied despite the picture showing 16 Gauge). In order for the pins to hit the wire when the cable is pieced they have to be perfectly aligned. I learned from other reviewers and just bought some 14 Gauge wire instead, which gave me the desired thickness of copper to work with while maintaining flexibility when trying to bend the wire and push the pins into it. To keep the transformer on to check each connection I simply used a small piece of electrical tape over the sensor. I used a small nut driver to push the cable up into the light base pins while using the base of another (screwdriver) to hold the top part (where the light bulb goes) into place. Also contacts for the bulbs come very close together, are easily bent. If the bulb doesn’t light after some manipulation of the bulb, pull the bulb base off, look at the wire and likely you’ll see the perforations were off kilter, though with the 14 or 12 gauge wire this should not be a problem. Use your screwdriver to bend the pins in the proper direction and try again (but don’t push the cable up into the housing with anything that will conduct electricity if you still have the transformer on. Having a voltmeter handy is nice, so if still the bulb doesn’t lite, you can check the voltage across the bulb contacts. On a couple of mine it was hard just to get the bulb to contact properly and that’s what was wrong even though the cable connection was good. Don’t stake any of the lights down until all are connected and all are lit.Once you get the idea of what your doing on the first light, the rest are quite easy to install. Unplug the transformer… install light, plug in to check if it works… repeat until finished.Now all this works great for the pathway lights, the spot lights are another matter entirely. What a major pain in the butt to get installed. The major problem with the spot lights is there is no cam (the little thing that in the pathway lights, helps to keep the cable connected to the pins) for use in these. You push the pins and cable together, and attempt to set the “correct” angle for your spot lights, and place in the ground, the problem comes that if you Move the angle in which the spot light is set in the slightest without some major coordination of moving the cable along with it, the pins will come right out of the cable and your back to square one. Major flaw in setting these up. Setting up the two spot lights took longer than setting up the pathway lights.So only 3 stars for this product, minus one star for the crappy 18 gauge wire they sent, and I had to go out and buy 14 gauge wire. Minus another star for the shoddy spot lights.Otherwise, it was a fairly simple set up. I haven’t had any problems with my transformer blowing yet, so do not know as to the longevity of the product.If anyone knows of a link to finding decent / equivalent LED’s for these lights, please let me know. Getting into Lumens / mCd vs Watts is a whole other story.
