Q: How much is the LED to shoot the light, color rendering index in general: According to difference of each manufacturer to purchase the lamp bead and shoot the light color rendering index, general Ra between 50-90. LED white light than warm white color rendering index is relatively high, general manufacturer to produce LED lamp color rendering index in more than 70

Q: Motorcycle lens and the LED lamp can be installed at the same time, and shall not affect the circuit?: Can be a switch control by an external switch to control

Q: The difference between the LED lamp: The price Canister light usually have a big (5 inches) in the (4 inches) small (2.5 inch) three. Small between 15 to 20 yuan, the market price of the number of 28-32 yuan between, large-sized between 36 and 48 yuan between. All prices above do not contain light source, of course. Canister light have horizontal and vertical two, flat a little more expensive than the vertical. Is important to note that close exposure lamp generally cannot be used for wool fabric, also can't close any flammable obstacles, otherwise easy to cause fire. Although the lamp power consumption but more in place with its ornament effect. Shoot the light as well as distinctive flavour to the adornment of the five lights cup.

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: 18 w changed other power drive not bright LED lamp, what reason be?: 42 v only do as much as 14 w, this is the most basic request, if I see this kind of drive is absolutely can't use, because the basic common sense all wrong, quality), the voltage is not enough, so is certainly not the light, do you want to buy a maximum output voltage at least 54 v drive

Q: As title, please the personage inside course of study to explain to shoot the light and PAR light some of the differences in structure and application fields, especially for the requirement of power supply. Thank you very much!: The lamps and lanterns of shoot the light is a highly concentrated, its light is a specific goal. Mainly used for special lighting, for example to emphasize a very tasty or is a very interesting place. Can be applied from the light source, location, and price comparison to distinguish the two kinds of the characteristics of the lamp.

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: The original old how long pole to shoot the light to LED lights: LED Chinese as the light diode semiconductor has positive and negative May be you take input power + - backwards and thermal conductive glue stick to a high power LED lamp bead need radiator panels mountain or you will burn out

Q: What's the reason why LED lamp explosion?: The LED is a semiconductor products, semiconductor components how to fry, you first take a look at what is inside shoot the light structure, what of? LED lamp is the low voltage dc power supply, so there is a 220 v low voltage transformer, rectifier, regulator, etc, so easy to explosive components only capacitance. Light not bright, then is a problem with my line, not LED lights out of the question, you think about it, four straight LED lamp is not bright, it happens only line out of the question. 1. You check the dc voltage in a circuit is big (a big will burn out the LED voltage); Check if there is no failure to press 2 points; 2. Did you check the rectifier voltage regulator internal burned components (including capacitor); To eliminate the transformer in the 【 some lamps and lanterns, to step down with other components, if one element is broken (short circuit), it is possible to high-pressure came in." 3. You're not short circuit has been measured using a multimeter, you is which part of the test? You didn't speak clearly. Dc voltage test have no? How many volts? 4. There is another reason is that the power supply voltage stability where you live? Have 220 v voltage fluctuations, especially at night, usually higher voltage (more than 220 v), if the voltage rises to more than your pressure limit of lamps and lanterns, lamps and lanterns will burn out. 5. Etc.

Q: The same power of cob and led lamp which is brighter: LED lamp now single lamp and COB of useful products, according to the principle of the photosynthetic efficiency can distinguish under the same power that or bright.
