Q:There are no holes 7 cm, 9W led downlight

Between general 7-12W hole 9.5 cm can be chosen, the LED lights our company own, opening 9.5 cm, 9-12W, 7W ceiling light is also your choice, to choose a bright power point, brightness not too big, choose a smaller power good enough!!

Q:How much LED 150W downlight spiral energy-saving lamp replacement

I do the lighting! First, where do you use 150W energy saving lights? With 150W energy saving lamps will only be used in industrial and mining lights, indoor general lighting is unreasonable. Simple answer to you, the general energy-saving lamp (60ml/W) lumen is led (120ml/W) half, that is, 150W energy saving, with 75W LED can replace brightness!

Q:The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?

The office uses 4 inch and 6 inch downlight, lighting power within 12-20w, ensure the light illumination to 100-200LUX office.The brightness of the corridor can be slightly darker, with 3-4 inch LED lamp, lamp power in the 6-12W, the more suitable for light illumination to 50-100LUX.

Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?

Pull a downward edge can be pulled out, which is two spring clip. Check the porcelain plug for disconnection or poor contact. If not, you can judge that the LED is broken and the lamp shop is on sale

Q:Turn off the lights after the bright LED lamp

The choice of switching error, with indicator light (excluding fluorescent) switch is not suitable to control like small power LED energy saving lamp load, because the load current through the indicator light through to the small power is not already small. A resistor of several hundred K in parallel with the ends of the load can be improved, or the indicator light can be changed directly, and the indicating lamp for canceling the switch can also be improved.
