Q:The same power of cob and led lamp which is brighter

Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.

Q:General how many watts of led to shoot the light, the most is how many watts

?Use LED panel lights, with the scale of the 300 * 300 mm, is about 10 w. Family condole with LED lights, can use 3528 light band. Wine cabinet or closet to choose LED tube light, can use 1 w or 3 w. Such as toilet, cabinet room, choose LED to absorb dome light, can choose 8 to 15 w dome light, can according to the area of economics in detail for selection. Families with LED lights usually choose how many watts is better?

Q:Sitting room condole top round with tube lamp or LED lamp good?

If simply on the role of lighting with leds, more energy efficient, but cost is higher (actually a year to save electricity I guess there isn't much, psychological effect is greater than the actual role). Canister light that individual is not very recommend, general tube lamp light source is energy-saving lamps, looks uncomfortable

Q:What brand of shoot the lamp to LED lamp of choose and buy skills

View the lamp parameters 1. The main parameters of LED lights, especially in high power LED lamp bead has a luminous efficiency and color rendering index, index of the luminous efficiency is 80-100 lm/W, must be greater than 80 LM/W, but the indicators are in growth, to the next year will reach 100-120 LM/W. Color rendering index is 0.8, the index is unnecessary to pursue more than 0.85, unless you are engaged in painting on color high requirements of the job.

Q:What is the price of an led light?

Suggested that before buying compare several brands, more cost-effective choice, of course you can also online mall, usually the price will be more cheaper.

Q:LED lamp biggest can do how many watts?

Shoot the light is a broad concept, source of coherent light can be classified as to shoot the light, shoot the light, such as smallpox large wattage lamp can be classified into the light. In the industry generally called PAR20 size small lamp holder to shoot the light, this kind of lamp in accordance with the lamp bead quantity biggest can make 5 * 1 w, 3 * 3 w. Above PAR30 habit called PAR lamp, size is larger, 18 w can do it. Other large wattage of the gymnasium, outdoor project-light lamp, stage lamp wattage do 200 w is very normal. The hope can help you

Q:Home use shoot the lamp to general how many watts is the best?

1, energy conservation: the same power of LED lamp power consumption is only 10% of incandescent lamp, energy saving than fluorescent lamp. 2, long service life: LED lamp bead can work 50000 hours, longer than fluorescent lamp and incandescent lamp. 3, adjustable light: previous dimmers has always been for incandescent lamp, incandescent lamp dimming the light is red. It's hard to see fluorescent lamp dimmers, this is dimming technology for many years the main reason for no development; Leds can move light again, and both light and dark are all the same color (color temperature constant), it is better than incandescent dimmer. 4, can be frequently switch: LED life is calculate by when lit, even if the switch is thousands of times per second also does not affect the LED life, in the frequent need to kill bright occasions such as adornment, leds have absolute advantage. 5, color is rich, is white, warm white light, colors such as red, green, blue, whether it is in the living room beside the headlight small lights or neon lights for ornament, is very bright. 6, low calorific value, like to shoot the light, a lot of 220 v incandescent lamp with not a few days is broken because of fever. 12 v halogen lamp calorific value is lower than 220 v to shoot the light, but there is another due to the lack of power distribution transformer, its brightness than the nominal value. Use LED lamp, no transformer can work long hours.

Q: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

Want to good quality and low light failure products, as related to factory for the level of power and thermal design of selecting well-known manufacturers as far as possible, especially for osram, philips companies such as foundry, such basic on technology and quality are guaranteed, the price can also accept, the design of the factory do is good, is a simple test can probably understand: the lamp light up more than half an hour, touch the outside of the hardware, if very hot, that don't do a good heat dissipation, light failure will be faster, generally speaking, there are little hot is normal. LED selection is very important, import slightly better than domestic, but imports also have light failure quickly, preferably is Japan's LED chip, and then the European and South Korea, is in the United States again, finally is domestic larger (brand), do not recommend using home-made low-end LED, quality can't guarantee!

Q:What kinds of leds are included?

MR16, GU10, GU5.3 lamp holder (or holder) models, are these MR16 is two needles into, low pressure, need to be equipped with a driver; GU10 and GU5.3 is high voltage 220 v. And spiral lamp holder E14 and E27, E27 is home commonly used lampholder, E14 smaller than E27. As we have the CPL lamp cup lamp holder. As for the LED lamp 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.

Q:Led lamp light source plate can change yourself?

Can change the lamp bead, light source is welding on board!
