LED deck lights

[ramjam]

I'm trying to install some LED deck post cap lights. I have installed many low voltage light systems in the past with the simple clips that get pushed onto the line wire. But these LED lights have plain wire tails(one red, one black 18-20ga). I'm assuming the main line wire just needs to cut and these ends get connected to them with wire nuts. There is an existing 12V 700W transformer that is being used for two landscape circuits that I will be connecting the new lights to. I also need to install a couple LV incandescent stair lights(preferrably on the same run).

So my questions are:

1. Is the proper way to connect the LED lights cutting the line and connecting to the tails with weather proof nuts?

2. Can the LED lights be used with the existing transformer?

3. Can other LV incandescent lights be used on the same run with the LEDs?

Thanks, Dave

Two questions that need to be answered before you can get your answer.

What is the voltage requirement for the LED lights that you own?

What load do you currently have on your existing transformer?

Weatherproof wirenuts will work just fine. Another options if its not to late would be to return the cap post and get Solar powered ones.

The two circuits on the existing transformer total just under 200W. The new lights(LED and incandescent) total 95W. There is one empty circuit available. I want the lights to be controllable by the timer on the existing transformer so solar are out. I'm just unsure if the LEDs need a special transformer. The limited information that I have been able to find mention DC transformers for LEDs.

Is your transformer an AC transformer or does it also convert to DC? Your incandescent lamps will have that info on them. If they are AC lamps, then no, the tranformer you have won't work without adding a DC converter.
