Electrical wiring for LED garden lights

LED LIGHTs (2): IP65 sealed, 2 pigtail wires sticking out for 120V connection. 9W 660 nm LED.

120V SOURCES (2): Exterior outlet with weatherproof cover and switched exterior light housing, both on the same wall. Preference is wall light housing (E26 bulb) because it is on a switch.

USAGE CONDITION: LED garden lights will be powered on in September and October. Purpose is to prolong growing season by 2 months.

QUESTION: How do I actually run a wire between the source and LED light?

Thanks.

The lights you posted are 12 volt not 120 volt. Are you sure these are the correct lights? The wiring method for low voltage lights is quite different then normal 120 volt wiring.

But most colored LEDs don't output UV light and I see no mention of the lights you linked to being grow Do White and Colored LED's output UV?

This is the right one:

For prolonging growing season with delayed flowering, one needs deep red, not UV or blue. Some plants get into flowering/seeding and die.

By the way, my plants will get normal sunlight during daytime. I am not growing plants indoors as some do for marijuana. They would need full spectrum light. My need is different.

How should I do the wiring that will endure 2 months of outdoor exposure?

Using 120 volt lights is going to make this much more difficult. I can't think of a really easy code compliant way to do this. You will need a weather proof junction box for each one. The code correct way would be a UF-b cable buried 24 inches connecting each one. Maybe you can jerry-rig something with SOJ cord and weather proof junction boxes that just plugs in. Then just have one permanent receptacle at the location. The pros may have a better idea.

This is the problem with cheap foreign made electrical products not specifically made for North America. I doubt they have a UL or any NTL rating and were not made to conform to U.S. codes.

Is there some way the fixtures could be secured to the wall and pointed toward the plants?can you post some pics of the area you are working with?

To run power to the lights you can either bury the cable/conduit in the ground as Ray suggested, or run conduit on the surface if it can not be buried.
