LED downlight luminous lighting brightness is not very large, it is better to be close to the ground, but don't reach people's heads, so it is best to be 2 meters from the ground, and you can calculate it yourself from the ceiling.

It is necessary to combine the height of the ceiling, the area of the ceiling and the power of the bulb.
To give you a reference: the general routine is that the longitudinal spacing of 15 cm ceiling lamps is meters, the horizontal spacing is meters, and the horizontal spacing of 25 cm ceiling lamps is meters, and the longitudinal spacing is 3 meters.

Generally speaking, the spacing is not fixed, if you want to be the main lighting light source, you can distribute it closer, so that the light source is more dense, and the brightness is also high, of course, if there are other main lighting sources, this spacing can be narrower. I hope my answer is useful.
The distance between the original ceiling and the ceiling needs to be 8 cm to 10 cm for LED downlights. >>>More
To see how big the downlight is, whether the other party has high requirements for brightness, if it is not high, it can be farther away, and if it is high, it will be denser.
The biggest feature is to maintain the overall unity and perfection of architectural decoration, and its development has developed from the general light source to the current popular LED light source, each with its own merits. >>>More
