About the installation hole of LED recessed ceiling lights

     The LED recessed ceiling lights installation hole edge to the edge of the ceiling should be greater than 5 cm. First determine the position of the keel, calculating the distance. If it is plasterboard should to open hole before brush coating. The ventilation pipe is generally on the ceiling, pay attention to the surrounding there is no sewer, to calculate the bending size of ventilation pipe before the ceiling decoration.
     To open hole for LED ceiling light in the integrated ceiling, pay attention not to open  hole on lightgage steel joist, avoid damage to load-bearing structure.
     As far as possible to open hole in a plate, avoid open hole on the connections of two or three plates.
     To open hole before brush paint. LED ceiling fixtures diameter measured before open hole. Then draw a "+" in the gypsum board, the "+" is the length of the lamp diameter. Then use the wallpaper knife rip open along the "+" on ceiling. Then cut a circle according to the "+", that's it. Notice that, try the lamp whether it can be put into hole after the open hole, and then take it out and brush paint. To installation lamp after the dry of latex paint.

How to choose the LED trunk ceiling light

     Choose the LED trunk ceiling light mainly from three aspects to consider:
     The heat radiator of lamp: The heat dissipation speed of light bead determines the light decay degree and the service life of the lamp. The light bead long time working in high temperature status, the light decay very fast, life is short, and the brightness is too poor, would not achieve the effect of accent lighting. The size of the radiator, aluminum quality affects the speed of heat dissipation, but also affect the whole lamp prices.
     The power supply of lamp (commonly known as drive): drive supply quality also determines the life of the whole lamp, lamp beads used more than 50000 hours no problem, but if drive is bad, the whole lamp can not be lit. The drive's efficiency, power factor, stability, temperature rise, service life be decided by electronic components and design of drive inside. If users do not understand them, you can preliminary judgment from the drive size, weight, and consult the manufacturers use electrolytic capacitors and other aspects. Differences prices of LED trunk ceiling light, power supply quality accounting for no small proportion.
     Light bead's brand and package: light bead's quality decides the lighting effects of LED track spot light, packaging process is a key factor to affect the light bead quality, heat dissipation. Light bead has the United States, Taiwan and domestic etc.. Different brands, price difference is bigger, the lighting effect is different too.
