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

Spotlights, 7 cm can do, and if you feel dazzling, you can use acrylic diffuser plate to do astigmatism, you can also adjust the angle

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:Led downlight can light panel directly with intelligent dimming Mody?

The lights can only be switched on, because the way LED works is different from ordinary incandescent lamps, and dimming panels designed for incandescent lamps cannot hold LED. If you are using the lamp holder and driving split LED light, you can choose an output voltage, current, the same, to support dimming drive to replace the original driver, in order to achieve dimming

Q:LED lamp power off why would light up

LED lamp power off, will light up, this situation is normal in the 220 electric power supply situation, reason is caused by the distributed capacitance charge discharge line.Because the switch and the lamp is connected with 220V/50Hz AC power supply is normal, directly added to both ends of the lamp, the lamp work light; when closed, switch capacitor and lamp itself and the line is connected to the alternating current of 220V/50Hz, because the distributed capacitance of the charge and discharge can form weak current, the lamp will light.Solution: in the lamp circuit board input end in parallel with a pressure resistance of at least 400V of non-polar capacitor, capacity 0.05 micro method above (if the switch connection is longer, can be appropriately increased).

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

Big ones. 6 inches. Our company is using this big one.

Q:What is the role of LED downlight

In fact, choose a good day Lantern is a LED lamp energy saving function, ordinary energy-saving lamps should be minimum 5W is generally 11W, a LED lamp bead is 1W, long service life, ordinary energy-saving lamps have radiation, light at 400 nm will produce ultraviolet light is harmful to people, UV will attract insects so the general energy-saving lamp has bugs in the circles above, the LED will not produce ultraviolet

Q:How many good color family LED downlight

The living room should be according to the style of the decoration. The Yellow warm colors with brilliant style, bright and clean with white, as long as the color temperature is more blue, like moonlight, lower yellow, like the sun sooner or later (incandescent light) color, like the 4500-5000k noon sun

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.

Q:LED downlight downlight and how to distinguish?

The lampshade can be made exactly the same. Distinguish between LED and ordinary lamp can see the inside of the light source, is a common lamp installation of energy-saving lamps. It is an LED light source lamp

Q:LED downlight, embedded lamps, lamp tube and difference?

No LED lamp lens, no light, light uniformity, light angle.LED recessed lamp is in accordance with the method, there are two types of installation and embedded installation. The recessed lamp is mounted inside the ceiling.LED cylinder spotlights have lenses, focus light, first focus on a place to illuminate, and where the illumination is high.
