One of the most direct differences is the type of light source. LED downlights use LEDs exclusively as the light source, while recessed lights can use a variety of different light sources. Traditional recessed lights often use halogen lamps, incandescent lamps or fluorescent lamps, but with the development of LED technology, more and more recessed lights are beginning to use LED light sources.

LED downlights usually have a larger beam angle, usually between 60° and 120°. This means that they have a wider range of illumination, can illuminate a larger area, and provide uniform light distribution In contrast, LED spotlights have a smaller beam angle, usually between 15° and 45°, and focus on concentrating light on a specific area or object.

If your LED downlight is a removable bulb type, the disassembly steps are relatively simple. Usually, the bulb of the LED downlight is fixed to the lamp holder by a clip or thread. Gently twist or press the clip to remove the bulb from the lamp holder.

Places that are not suitable for installing LED lighting downlight include: 1. Wet or high humidity environment 2. High temperature or extreme temperature environment 3. Too low ceiling space 4. Frequent switching scenes 5. Places that require extremely strong light output 6. Art galleries or special exhibition spaces 7. Direct exposure to strong impact or vibration environments

Reasons for LED lighting downlight flickering: 1. Unstable power supply voltage 2. Driver power failure 3. Quality problems of the lamp itself 4. Improper installation 5. External electrical interference 6. Temperature factors

LED lighting downlight refers to a cylindrical embedded lamp that uses LED light source as lighting. It is generally installed on the ceiling or other blank positions where light source is required, and the light is irradiated downward through the outer shell of the lamp.

For LED downlights installed in the bathroom, although many LED lamp designs use electrical insulation protection, grounding is still very important because the bathroom is a humid environment. For LED downlights without insulation design, grounding is a necessary measure to ensure their safe use.

Although the LED chip itself requires direct current to work properly, most home and commercial power systems provide alternating current. Therefore, when the LED lighting downlight is working, it needs to convert the alternating current into direct current through a power driver module.

Lumens are not directly equivalent to the intensity of lighting, but rather a measure of the amount of light emitted by a light source. In simple terms, lumens describe how much light a light source "emitted", but do not necessarily reflect the "brightness" of the light.

Generally speaking, when the LED bulb reaches the specified life span (such as 25,000 hours or 50,000 hours), its brightness will drop to about 70% of the initial brightness, and the LED bulb needs to be replaced at this time.
