Q:A few questions about LED lights

1 power supply voltage must be the same as the load, the power of the output current is larger, can provide the greater the power, the power of the load ability is stronger, so the output voltage of 12 v, the power of the output current of 700 ma can be used for you to shoot the light. Of course, if a larger output current of the power supply can also use just a little too wasted. 2 and 3 for the power supply voltage of 24 v, most likely have to burn the load (leds and circuit component), if want to use, with a voltage divider to be available 24 v down to 12 v. 2 the output current and load is the same, but actually does not reach 350 after partial pressure and loss ma output, so 2 after decompression can not use or scrape can be used. 3 the same supply voltage is too high to buck can use until about 12 v, otherwise it will burn, 700 ma output current can meet the requirements of shoot the light. Summary: the power of the output current must load than old do line, otherwise due to the load is too heavy to burn the power supply, power supply voltage and load the same or close to, can have a little error, but the difference is too large, high voltage too much, may burn load circuit and LED (lamp), is too low, could not move or inefficient work load and the load is not work.

Q:How bright LED globe bulb 5 w? The light is to shoot the light, or like a glow around?

A 5 w LED bulb brightness because of the different vendors lamp bead, the total brightness is different, our company do the white light of the 5 w bulb USES 110 lumens lamp bead

Q:Do household LED lamp (70 w 12 v) an hour how many kilowatt consumption???????

Electricity is very little,0.07 watts.Is a kilowatt hours of electricity for a time

Q:Led bulb light beam width led ball steep light Angle is usually?

These lights in addition to the LED fluorescent lamp is 1 wled do, you will find your LED lamps and lanterns of parameter has its light Angle, generally is 160 degrees, one is 160 degrees, 10 or 160 degrees, what do you say? And the LED fluorescent lamp is made of 3528 LED, the light Angle is greater than 120 degrees

Q:LED track lamp series and LED lamp series, what's the difference?

Track light is actually a kind of shoot the light, only can moving in orbit

Q:What kinds of leds are included?

The advantages of the led lamp: Energy saving: equal brightness for ordinary energy-saving lamps a quarter of the power consumption. Environmental protection: no mercury and other harmful substances, no pollution to the environment. (the expert points out: a fluorescent energy-saving lamps including the pollution of mercury can be 180 tons of water). Economy: save electricity can reduce electricity costs, a year and a half to recover the cost of lamps and lanterns. A family can save electricity dozens of yuan a month. Low carbon: save electricity is equivalent to reduce carbon emissions. Longevity: the life of the LED lamps and lanterns is 50000 hours, using six hours a day, is the life of 20 years. Price is also see you need wattage to determine, different wattage the price also will be different. Now USES is "flash" led in the home, very good, prices that are both good quality, you can go and see. The hope can help you. Wow kaka

Q:How to distinguish the stand or fall of the LED lamp

LED lamp cent two kinds of low pressure, high pressure, consumers had better choose low voltage lamp, its long service life, high light efficiency. Shoot the light efficiency of high and low to power factor, power factor, the greater the photosynthetic efficiency, the better, the power factor of ordinary lamp at around 0.5, the price is cheap, high-quality shoots the lamp power factor can achieve 0.99, the price is a bit expensive. Shoot the generally used to strengthen the lighting on the trim, general is embedded in the ceiling or wall, LED to shoot the light work generally have a higher temperature, so set to buy the high quality product, otherwise there will be a security risk

Q:12 LED lamp power driver is good But not all bright can fix

This is all 12 lights series, if really bad one, all all is not bright, but the short it is ok to pick up the bad. You can live under test lamp red black line on the board, the normal light bead on the voltage should be within 36 to 40 v. If the drive is normal, and light bead is broken is not bright, voltage should be in more than 50 v, even more than 200 volts.

Q:Is the radio light charged?

Quartz lamp is inefficient, the LED lamp is very save electricity! Lamp can adjust the Angle - limited to where you want to shoot. The canister light Angle is fixed!

Q:Questions about the LED lighting of an electric car

The LED lamp voltage is very important, is the voltage problem. When the two tests on the battery voltage are you tested?
