Q:Friends have told me that the Hong Kong star can lighting production of LED lamp, LED bulb light. LED daylight tube is very save electricity, I find for a long time to find, now share with you what? Who can tell me what is he power-saving principle?

Leds into visible spectrum efficiency is high, with the same voltage, electric current produced by the visible light, electric touch less radiation and heat, power saving a lot of the same brightness LED.

Q: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

Q:LED lamp burning halogen lamp cup of transformer

Is your estimate of transformer electronic transformer. High frequency and voltage instability. With a constant current source or inductance transformer next time. When I was home decorate is to ask the manufacturer. Did you change all buy it. Introduce you out of the blue lights. Is responsible for. Just tell me how to pack before I buy. There may be any problem. Do help to save money worry

Q:The led lamp is suitable for reading?

To reading lamp can choose color is white, 3 w shoot the light is illuminated distance is limited, additional LED shoot the light when there is a shadow of the fluorescent lamp is not. Your room how many lamp?

Q:Does the LED light have to be transformer?

It's not called transformer. LED lights need drive power, has permanently flow drive and resistance capacity drive, usually 220 v50hz ac power input.

Q:1. I bought the LED tube light, there is some light is driven with constant current, while the input voltage is 220 v, but tend to be low voltage dc output voltage, there are some inserts the 220 v can directly, didn't see any of the constant current drive, so is built into the still say there are two kinds of LED tube light, is a kind of the working voltage of the dc low voltage, a kind of ac 220 v. 2. About the LED tube light, dimmer, I already according to one of the LED constant current drive found the corresponding LED light, that if I was the LED directly to the adjustable light can directly replace the LED constant current drive.

LED lamp bead are dc low voltage, single grain lamp bead generally around 3.3 v voltage can light up, general household LED light has many grain of lamp bead, most of them are in series, no matter which kind of LED lighting needs to be in the form of a voltage conversion device, the voltage conversion device also has a built-in external, have stable manifold has regulated form, useful integrated circuit do useful discrete component, with complex circuit has simple circuit, there are lights and conversion circuit package together also have lights and conversion circuit of separate, anyway is multifarious, various countries now also does not have a specification, each manufacturer yourself, just do what want to make it, so they bring inconvenience to the user, so the home LED light damage, it is difficult to buy the same, every time in the lamp will also ask professional to listen to, you say the problem is not surprising, is likely to be a built-in driver, another oneself need plus drive without a driver.

Q:How much is five inches square led high power lamp

Due to the small shoot the light can be combined free transform perspective, lighting effect. Shoot the light is downy, elegant, its also can local lighting, foil atmosphere

Q:What kinds of leds are included?

LED to shoot the light is roughly including LED lamp cup, LED ceiling lamp, LED downlight etc, PAR lamps and the LED lamp, LED bulb is not big. Because the lamps and lanterns of LED lamp is refers to the condenser, and the ball bubble lamp is glistening divergence. Former friends right!

Q:Led lamp light source plate can change yourself?

If sure just light bulb is broken, if change is not very troublesome, then change the light bulb, because the lamp you use isn't a long time, you can buy a light bulb, because they are for my own household, expensive with the cheapest price

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

This kind of situation should be how to I have several are the problem They can't spell some of my good to come out
