The main safety issue with downlights lies in the lamp holder. Some off-brand downlights have lamp holders that are not heat-resistant and easily deform, making it difficult to unscrew the bulb. All lighting fixtures must pass 3C certification before they can be sold; consumers should choose downlights with 3C certification.
Another important factor is the thickness of the panel, which determines the price of a downlight.
Regardless of the type of downlight or spotlight, all downlights generate heat. Avoid placing them too close to walls to prevent yellowing of the walls.
