Let’s start!

What is pot light?
Pot lights are modern lights that can be directly installed inside the ceiling or wall. It can be made of LED, fluorescent, halogen etc, but LED is the smartest and most popular.
It comes with three components: housing, trim, and bulb. The housing is the body that holds the light parts. Trim is the visible portion of light that can be decorative or plain. The trim filters balance the light’s color and spread. Finally, the bulb is the part that produces light.

History of pot light
The history of pot light takes us to the 1940s. At that time the concept of installing the light inside the ceiling appeared. This type of light was used in shop and commercial spaces to create balanced lighting. How a product looks in the shop directly affects its sales. Good lighting is essential for that.
In 1956, a company named Halo started producing recessed lights commercially. Their first product was named H1. After the great success of H1, they brought different types of pot lights, H2 to H7 to the market. Those lights are still being sold.
Later on, those lights started gaining popularity in private housing. Previously, incandescent and fluorescent lights were used in pot lights. After the invention of LED lights, it became the best choice for slim panel. LED lights are far more energy-saving and convenient than others.
How pot lights work?
These lights can be made of fluorescent, halogen, or other types, but LED bulbs are most common. LED lights produce light completely differently from other types of light. The full form of LED is light-emitting diode. The diode is a semiconductor microchip that releases light photons when electricity passes.
Other types of light generally use heat to create light. Those lose a lot of electricity to work. LED is the most efficient light option we have. It loses less than 20% of electricity on heat. Thus it uses 80% less electricity than regular bulbs.
Types of pot light
The types of pot lights can be categorized depending on different segments. Let’s take a look at them-
- types depending on size
- types depending on the function

Temperature guide of pot light
The color temperature of lights describes how warm or cool the light is. When choosing a pot light color temperature is a vital factor to consider. Some lights have different color settings which are best if you want more control on light color. Here are the temperature categories of the lights-

- Warm light: 2700K – 3000K (yellowish light)
- Neutral/Balanced light: 3500K – 4500K (white light)
- Cool light: 5000K – 6500K (bluish light)
You may ask what to do with the temperature of a light. Let me explain. In most cases, lights that have neutral color are best. However, warm and cool lights are better suited for specific uses.
The warmer the light, the more comfortable you feel. It has less clarity but has a calm character. Therefore, it is best for bedrooms.
Neutral lights are better for most other spaces, like dining, kitchen, bathroom, etc.
Cool lights are more clear. It improves focus and visibility. So, cool lights are best for reading and workspace.
How many slim panels do you need in a room?

It depends on a few important factors. The height of the ceiling, light power, and what your preferences are. But for general seamless lighting, you can follow an easy rule.
The pot lights should be half the ceiling height from one another. Let me break it down for you. If your ceiling is 10 feet, the lights should be 5 feet from each other. You can adjust the distance a bit according to your needs and preferences.
