LED troffers and LED panels are very similar when it comes to where and what they are used for. These types of panel lights are used for both residential and commercial applications such as in homes, offices, hotel lobbies, restaurants, supermarkets, hospitals, and more. They often replace CFLs and are designed to mount on either suspended grip ceilings (LED panels) or recessed lighting (LED troffers).
Here is the main difference: LED panels are used to replace existing fluorescent ceiling lights and require much less space due to their slim build. LED troffers, however, are rectangular and are designed for a modular dropped ceiling which require more space for installation.
The beam angle of an LED bulb is the angular dimension of the light coming from the lamp that spreads across the floor when on. It encompasses the central part of the beam out to the angle where the intensity is 50 percent of the maximum angle. For most household ceiling fitted applications, a beam angle of 30 or 40 degrees would be sufficient.
For outdoor applications, a wider beam angle of 60 to 120 degrees is preferred to cover a larger surface area. LED troffers and panels are often used for general lighting to make you feel safe and comfortable.
