Q:Excuse me how many W LED lamp appropriate gallery

Color rendering index suggested that more than 80 Ribbon star lighting technology

Q:Tube lamp, metal halide lamp, lamp, LED lamp, the difference between more than advice please!

Tube light is used for general lighting, can use energy-saving lamps and LED lights Metal halide lamp together not concentrated mostly see shape, but the metal halide lamp used for local lighting effect is very good, like a clothing store Than metal halide light that shoots the light is weak, but stronger than canister light LED just refers to the light source, with energy-saving lamps, incandescent light bulb is a concept

Q:Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?

Ok, now are LED lamp to replace the original quartz bulb,Can be used, but there must have a circuit inductance/curtains on tube/semiconductor current limiting device (using single-chip microcomputer control)!!!!!

Q:Decorate the house, to shoot the light tube light a matter of choice

In order to increase the decorative condole carries on the way to you is for design. If only 6 lamp, it should be a shoot the light, because the location you selected is a need to soft light, so I suggested that 3 w warm white leds. Lamp with I suggest to white color, if metope is light coffee, the top surface should be white, generally in the application of brown metope top surface should be widened with white stadia, let the height looks more appropriate. Setting wall of the round hole decoration I suggest you choose the color, brightness, because we didn't at the scene don't know the details of the shape. The lamp of the bedroom must choose colorless light warm color, is not the main light 3 w enough. Toilet should be above the lens headlight, the lamps and lanterns city of your choice.

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

LED lamp is a general term, it includes the LED track light to shoot the light, like the LED ceiling lamp, LED tube light, LED fluorescent lamp also is to shoot the light. If you don't understand can ask me

Q:The LED lamp how to choose and buy?

LED to shoot the light color consistency: the current domestic there are a lot of assembly house, large and small combined also have thousands of, of course, also have strong and weak points of the power. There are a lot of small assembly house because there is no testing machine, so either not testing, or outgoing. For such quality is difficult to guarantee.

Q:Led outdoor lamp on Ⅰ p65 what meaning be

IP65 dust said this product is 6 grade, waterproof rating to 5, how kind level of dustproof, waterproof, following detailed answer. What is the IP protection class IP (IP for Ingress Protection, abbreviation), IP Protection grade system is made up of IEC (International company Technical appointed the draft. Will be in accordance with its lamps and lanterns prevent outside content invasion, waterproof, dustproof, moisture proof the characteristics of classification. Here refers to foreign object contains tools, man's fingers are not in contact with the lamps and lanterns of charged part, in order to avoid electric shock. IP protection grade is composed of two Numbers, the first number said dust of lamps and lanterns, the level of the external things out; Second number said lamps and lanterns of moisture proof, waterproof airtight degree. The greater the number, said the higher degree of protection.

Q:Led track light to shoot the light can not track meet 220 - volt power supply directly

Led products are usually equipped with a driving power, please access to the manufacturer of driving power supply after use, so as to avoid damage to the lamps and lanterns. Power refers to the power source, a meter can amount to the output voltage. Is a kind of power conversion circuit, a so-called drive will be some form of fixed power into different voltage and/or different forms (ac or dc) is another kind of power supply, supply specific power demand of electrical appliances. So the driver himself into power after turn on the juice. Electronic products commonly used power adapter also is a kind of electronic products of the external drive. The LED chip is working in the low voltage dc, generally need to drive to provide stable voltage and the safety of current. The LED driver with built-in, there are external. Has internal drive leds is specified using power (such as ac mains, battery, etc.) through to can use. Need the external drive LED lights will be added with the appropriate power adapter (or external drive) to transfer the original power supply (such as mains, battery, etc.) to provide power LED chipset conform to the requirements of the work. If think reply results can please adopt oh O (studying studying) O thank you, if you have not understand place, please continue to reply.

Q:The luminous flux LED to shoot the light, technical parameters, MR16 GU10, chips and other parameters

LED shoot the light cup MR16 voltage: 12 v, 3 x1w flux: 240-300 LM this is to see what is the single light bead chip size to LM, like 45 ml 112 LM chips do no problem, then flux have 312 LM, GU10 voltage can be done as required.

Q:Store decoration, good track shoot the lamp to LED lamp or metal halide lamp is good?

LED lights. LED lamp is more energy efficient, longer life, and light failure is small.
