4.5-Watt Millennium Black Adjustable Light Color Outdoor Integrated LED Landscape Flood Light (4-Pack)

Using 12/2, low voltage landscape wire you can connect up to 20 of these lights. We've already connected 8 flood lights and plan to add more plus, some low voltage pathway lights, too.

2700 k is referring to the color or shade of the light , not brightness. The lower the k, the more yellow (warmer, softer) it is. The 3000 k is more of a blue (colder) color than 2700 k

Voltage dictates how far electricity can jump through air (or other insulators) like extreme voltage Lightning will jump across the sky. In contrast, Low Voltage (i.e. 20V) has trouble even walking across copper connectors (ie if tarnished), and will not short circuit through water unless the connector is really submerged. Prevent connectors from being completely soaked or submerged, and you should be okay.

The answers below are WRONG. Just look at the specs on the picture of the box. These are 20watt equivalent and 200 lumens. The specs for these on this website are wrong. If you want 400 lumens, you need to get the 9.8 watt version which is 50watt equivalent and 400 lumens.

They are not wired together but rather four individual lights with their own short cord and connector.
