View attachment 434974 I use these sockets (from Casa DePot) for the bulbs. The socket is inside of a solid rubber outer case and is waterproof. The wires are pre-stripped. You will also need a power cord, some wire nuts, a wire stripper, and electric tape.
For the power cord, I use a cheap extension cord and cut off the end with the sockets. Separate the two wires that make the cord and strip off about 3/4" of the insulation on both parts of the cord. On most cords, one side will be smooth and the other will have ridges. It doesn't matter which side of the cord you attach to the white or black wire on the socket, but if you are daisy-chaining lights, you want to be consistent. I always put the side with the ridges on the black wire.
Put the stripped end of the ribbed side of the wire together with the end of the black wire on the socket. Twist the two wires together, then screw on a wire nut. To waterproof the connection, wrap the nut & at least 1/2" of the wire tightly in electric tape, making sure to overlap the turns of the tape and completely cover the opening in the wire nut. Repeat with the other wire. That is all there is to making a one-light setup, you are ready to plug it in.
If you want to daisy-chain lights, you will need one power cord and a piece of the same type of cord without a plug. If your extension cord is long enough, you can cut off a piece of the cord to use to hook lights together. Separate & strip the wires on both ends of the cord that doesn't have a plug on it.
This time, twist the ribbed side of the power cord & the ribbed side of one end of the extra cord together with the black wire on the socket. Put on the wire nut & electric tape as before. Repeat for the white cord. This gives you 3 cords hooked together.
Then take the extra cord (that doesn't have the plug on it) and attach the ribbed side of the wire to the black wire of the next socket, then repeat for the white cord.
I dangle the lights down in any area that looks like it needs more light. It's not good to hang the bulb by the power cord, so I tie a piece of string (or twist one end of a long twist-tie) on to the bulb and use that to hang the bulb. This way, you aren't putting stress on the electric connections.
If you need more light in a spot and don't want to add more sockets, you can use a "Y" socket adapter to put 2 bulbs into one socket. This weighs a lot more than using just 1 bulb, so be sure to hang it securely and safely.
While the socket itself is waterproof, you still need to be very careful if you spray your plants with anything. Pull the sockets up out of the garden - any water that can get inside the socket (between the bulb & the socket) can still cause a short or worse.
I will get some photos illustrating the wiring this afternoon while I'm working on my garden. I may post it as a separate topic in the "Growroom Design & Setup" forum where it will be easier for others to find.
To remove the reflector from the light you are currently using, unplug it (for safety) and take the bulb out of the socket. Hold the socket and unscrew the reflector (turn it counter-clockwise just like unscrewing anything else). Once the reflector comes loose, put your bulb back in the socket, plug it back in, and you are in business.
