Q:How to judge the quality of LED downlight
Determine the quality of LED ceiling lamp lighting effect, the United States and Taiwan LED chip chip chip, domestic chip etc.. Different brands, different prices, lighting difference is also large. Special low price downlight, make many use of chip production line down the defective products, color inconsistencies, brightness difference, short service life, users need to pay attention to.
Q:There are no holes 7 cm, 9W led downlight
9W downlight generally open hole is 11 cm...Go and look for it on Taobao
Q:How to choose the right LED downlight
Look at the radiator lamps: cooling speed determines the degree of attenuation of the whole lamp and the service life of the radiator is too small will accumulate in the light of internal temperature. Light long time working under the condition of high temperature, light decay very fast, life is short. Our shell and radiator are all thick materials to ensure heat dissipation.
Q:How much is the general 15WLED lamp luminous flux.
Of course, can also use 30142835 beads to do warm (below 4000K temperature) will be low, cool (above 6000K temperature) will be higher
Q:Excuse me, how to install the LED lamp?
Lamps shall not be covered by any flammable substanceThe wiring of the lamp should not be close to the radiator, and should be avoided as far as possible
Q:Know the LED lamp wattage
There are regular W, 5W, 7W, 9W, 12W, 15W, 18W, 20W and so onSpecial requests can also be made if you have special needsIf you can tell me what you do, I can give you the recommended power
Q:Led downlight can light panel directly with intelligent dimming Mody?
We live by 220 volts of alternating current, and LED by direct current. So all the LED lights will be fitted with a driver to change the current and the voltage. LED lamp dimming according to the change of current or voltage, so Led can directly drive panel light lamp dimming and decided to use intelligent downlight! Ask the supplier can, but generally adjustable lamp will be specified, because the adjustable light is not adjustable to your light!!
Q:What is the size LED downlight
The inches here are inches, not ancient measurements, inches, feet, rulers, etc.. 1 inches =25.4 mm =2.54 cm (1 inch = 2.54cm)So:4 inches =4 X 2.54=10.16cm. About 10cm = 100mm6 inches =6 X 2.54=15.24cm. About 15cm = 150mm8 inches =8 X 2.54=20.32cm. About 20cm = 200mm
Q:LED is not only the benefits of downlight what harm?
Not good manufacturers can only be said to be defective, LED competition in the domestic market is too large, resulting in product quality, now there LED manufacturers can LED lamps prices do with energy-saving lamps are almost the same, I smiled, this is the difference
Q:How many good color family LED downlight
Personally feel about 3500K color temperature appears soft and warm. I hope it works for you
