Anonymous users2024-01-23If you often open the light strip, choose LED (that is, the secondary light-emitting tube), and use the T tube if you don't open it often, the T tube has a short life and large power consumption compared to the LED, but in terms of effect, it is very good. LED has a long life, low power consumption and low heat, but the lamp is weak and the effect is not good.

This is called the built-in light trough.
If you want to do it, it is more troublesome - you need to divide the ceiling into two ceilings and two edges. Wiring and installation of built-in lights are required. >>>More
If the ballast is broken, just buy a corresponding ballast and replace it.
It's best to use that light strip because it's soft, it can change with the shape of the roof you hang, and it's easier to install. Just like the side-lit headlights of the EHLTECH, they also use light strips.
Normally, the height of the ceiling light trough is 15 18cm, and the depth is 20cm; However, in some places the height of the trough is 8 10 cm and the depth is 12 cm.
Hello! You should be referring to the width of the bottom of the ceiling around this living room, right? The trough will not be 60 cm wide. >>>More
