FAQ

Old energy-saving lamps to replace myself home of smallpox, bought the Led ceiling lamp small transformer two outlet with L, N, and their charged to check the two connection of the old lamp base, there are thermal power, and ask the customer service, selling Led lights under said can both zero firewire, ask you confirm it, thank you
Basic products such as LED ceiling lamp, the lamp generally driven by constant current power supply, input is 85-265 - v ac, so don't points are negative. Now LED3W ceiling price is in commonly between 25 and 45 yuan, never buy the sort of more than ten dollars, bought a very headache, a few days or not bright, or gradually, there will be more and more dark, our house is filled with dozens of, want to find the boss, but has no time at ordinary times, so to now also didn't go to, don't know how to say that the boss will? Cheap goods is not good, say two years is not bad, I can't see with the Spring Festival this year
Aquatic plants cylinder light can use LED lamp?
Can carry out photosynthesis, aquatic plants,As for a professional player will not use led lighting as the lighting of the grass cylinder
The difference between floodlight and LED to shoot the light
Hello!!!!! Waterproof, omni can be waterproof, but it is difficult to do waterproof shoots the practicability, floodlight used outdoors, but shoot the lamp to be more used for indoor power size, floodlight can reach the maximum power of far distance is much bigger than that shoots the light projection, omni range than shoot the light
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.
Could you tell me how many watts of the led warm yellow light can be 30-50 w halogen lamp and concentrated and astigmatism reflect the same effect? My house seems a 50 w halogen lamp, I would like to change a batch of leds. But hope for light effect is the same, the price is not the problem, but must be good quality, low light failure
Instead of a 50 w halogen lamp, it will be with 6 w and 8 w LED lamp, LED basically see how high light efficiency, ensure that the total lumens is about 350 lumens, color temperature 3000 k, the better light Angle of 30 degrees, that can ensure the lighting effects.
What about the size of the led light?
Shoot the light is not a constant, the size of the first line is considering the wattage, and then there are different company's design style is also different in size.
Help: anyone know how high power LED small shoot the light and the light band?
You'd better send a real figure, usually seven holes on behalf of the seven LED lamp bead, a hole a lens, a lens with a lamp bead, a high-power lamp bead 1 w. 3 w. With seven of the 1 w lights is called 7 w, with 7 of the 3 w is called 7 by 2 w can also be called 7 by 3 w, lamp tape to see what is you use lamp bead, 5050 power is big, with 3528 power is small, and see how much you use inside the lamp bead, light beads also decides the size of your power
The sitting room decorate, LED to shoot the light with the circuit problem
If you are going to the remote control switch, it is important to note that the line walk good, reserve can open the location of the maintenance. Remote control switch you can check it online, general or more than three road all the way. Can also be a remote control remote control light some of the rooms respectively
