To get started installing LED Recessed Lights, there are just a few basic steps that you need to follow:
1) Decide on the layout of your lights and mark the location of each light on your ceiling.
2) Run wires to the location of each light.
3) Cut a hole in your ceiling that matches the recommended size on the product page.
4) Make your wire connections and snap the light up into place.

Deciding on a layout for your lights
Most people space their lights equally apart from each other forming a grid pattern on the ceiling. The distance between each light generally depends on the LED wattage of your light. Here are a few rough rules of thumb for spacing when using the lights as primary lighting (if you are using the lights as accent lighting or you have other lights in your room, you can space them further apart):
7W LED Fixtures (equivalent to a 50W standard bulb): 7W fixtures are generally laid out in a grid such that they are 2'-3' off each wall and 4-5' apart from each other.
9W LED Fixtures (equivalent to a 65W standard bulb): 9W fixtures are generally laid out in a grid such that they are 3' off each wall and 5-6' apart from each other.
15W LED fixtures (equivalent to a 75-80W standard bulb): 15W fixtures are generally laid out in a grid such that they are about 4-5' off each wall and about 6-7' apart from each other.
18W LED fixtures (equivalent to a 125W standard bulb): 18W fixtures are generally laid out in a grid such that they are 5-6' off each wall and about 8-10' apart from each other.

How to choose the lights color?
3000K: Used in family, hotels, coffee shops and other warm and sweet environment required.
4500K: Used in home where need a soft white lighting atmosphere.
6000K: Used in office, working area, shopping mall and other commercial area or some place where need super bright

Our lamps are made of acrylic material and plastic, the thickness is 2.5cm. Before installation, please adjust the position of the spring to ensure that the spring can rebound properly before installation.
Cut Hole : 6.7in (17cm) ≤ Diameter ≤ 7.4in (19cm)
This model of the light without junction box but with a driver. Brown is the live wire, blue is the naught wire. Due to the special design of this ceiling light, no ground wire is required and there is no risk of conduction. It can be soldered with a soldering iron (the soldering is full to reduce the resistance), finally the black heat shrinkable tube is used to shape it.
