Q:How to change the condition of light change the color of the led lamp?

In light with colored cellophane,There must be some! Is cellophane

Q:Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad

Lights, namely the number of lumens per watt, LM/W, he reflects the energy-saving performance of lamps and lanterns, power saving, the more good lamps and lanterns, the higher light efficiency. Current leds and compact fluorescent lamps and lighting, with the improvement of LED lights, CREE possible amount of output this year 186 lm/w illuminant. Cash supply high power DC - DC DC converter, DC booster, 36, 48 v/v / 60 v electric inverter, electric vehicle intelligent DC converter. 24 v - 72 v electric vehicle controller, etc...

Q:What's the reason why LED lamp explosion?

I come to the conclusion: your power supply voltage abnormal! Possible reasons: with your power supply system of a steal, (often at night, more time is that a) steal operation make the zero line suddenly dangling leads to voltage surge, relatively high voltage regular bulbs, not necessarily immediately, overflowing LED lamps and lanterns is very sensitive to voltage, slightly on the high side is easy to burn off one of the components (often capacitor). search Suggestion: immediately report power supply company, one night about the same time to check the meter box line condition!

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?

Different types of lamp bead is not the same, like LED lamp bead is 38 degrees to 45 degrees, SMD lamp beads is generally 120 degrees

Q:A transformer can shoot the light at the same time for several of the 12 v?

So see your transformer on load capacity and how much is the rated power 12 v lamp, also is the apparent power transformer (VA) is commonly used in, with the apparent power values divided by the lamp rated power (W) is commonly used in. If your transformer is 50 va, power rating of each lamp is 10 w, then can take a maximum of 5 lamps.

Q:LED lamp is negative would pick up the light damage?

How much driving voltage rating? Series number for how many leds, partial pressure of each

Q:Shoot the light track shoot the light

Next to convenient pre-loaded LED lamps and lanterns of choose and buy, major person has experienced change the awkwardness that sucks dome light bulb: stepping on a table, stepping a chair, hold one's head high 90 degrees, carry double arm overdoes 2.5 meters tall taller even ceiling. Replacement bulbs must consider when choosing lamps and lanterns is convenient. No room should choose droplight, because the chandelier lamp head to the ground distance is smaller. Energy saving is also very important, of course, LED lamps and lanterns are basically with the concept of energy saving, energy saving light bulb is saving electricity, lighting and good, also do not send out quantity of heat, applicable bull lamps and lanterns. Energy-saving light bulbs are mostly standard screw, and droplight has two kinds of caliber, one kind is standard, can use energy-saving bulb; A kind of non-standard, cannot use energy-saving bulb. Furthermore more product safety principles to consider, must choose normal manufacturer of LED lamps and lanterns. Formal products marked with the total load, according to the total load, can determine how many wattage bulbs are used, the most important, especially for bull droplight that quotas by each bulb wattage = total load. The other big humidity, should choose waterproof lamps and lanterns.

Q:Smallpox lamp is max25w LED power rating, is 25 watts

Listen to sell the lamp. LED light is very save electricity. No electricity. Here I'll use leds. Only 10 w tube light.

Q:What is the difference between LED ceiling lamp and LED downlight

Two lamps are installed on the top, the difference is the tube light is mounted into the dark, shoot the light is mounted, the tube light is diffuse light, mainly to adjust indoor light color effect, shoot the light is the direct light, is mainly used to highlight the background picture or object.
