Price different between the LED lights

In recent years,the led market is very fast developing.However, the price of all kinds of LED lights are have some distance,and the quality is different too.

Now the led light is nearly has the same market as the energy saving lamp.And more and more customers will buy LED light more than the energy saving lamp.LED is new technology,compared with energy saving lamp,the light is better,more power and longer lifespan. For example,the brightness of a  20-watt LED lights will better than 40-watt energy-saving lamps,and power consumption can save more than half.

Each led company will have different led brand chips for selling,and also there is a big difference in price between different products.For example,the price of the 5W LED spotlight, the ranging from 2USD to 8 USD, some even up to more than 13USD.Why there is some big different?The reason is quality,material,the light effect and life span are different.When you compared the led spots,you will feel the expensive one will much heavy,the led driver is not the same too,you also can see the different on the appearance.And the light of the expensive spot will much soft and with good lighting.About the cheap spot,you will find the light dim after a half year using.

But now almost all the led suppliers said the lifespan of the led lights are 30000-50000hours,but when do the guarantee is only 1-3years.The lifespan of LED lighting seems to be a “concept” for the customers.It is hard for the customers to choose a good led product.But pls trust us,we will be your reliable led partner.

2400K and 2700K flexible LED strip

Recently,most of our customers like the 2400K or 2700K led strips very much.Because the color will be much warmer ^_^

We are the led strip factory,so the cost of our flexible led strip is very good.We have waterproof led strip,IP65 led strip,IP68 led strip,colored strips and and nonwaterproof strip.Do you also like the 2700K strip and the 2400K strip?

The idea of the led panel is very simple. We light up the edge of light transmitting acrylic which carries the light into the panel.

Very good for office use and shopping center use.

 

Energy saved up to 50%. high brightness,even lighting output

4000-4500K(Natural white)
5500-6500K (Cold white)
RGB COLOR OPTIONAL OR CUSTOMIZED

Hot sell led spots—5W GU10

Here we want to recommend a hot sale 5W GU10 spot to you.

smd spot gu10                     LG Packing

 

This spot is with big angle:90deg.It is very good for lighting.We sell this 5W GU10 in big quantity.It is our best selling led GU10.The price is very good too.We can do it in dimmable GU10,the price is the same as nondimmable 5W GU10.Good packing for selling,we sure your customers will like it very much.We still can do in MR16 5W spot,E27 5W led spot.There must be the one suitable for you very much.

PWLED-RGB systems

White light can be produced by mixing differently colored light, the most common method is to use red, green and blue (RGB).
Hence the method is called multi-colored white LEDs (sometimes referred to as RGB LEDs). Because its mechanism is involved
with electro-optical devices to control the blending and diffusion of different colors, this approach is little used to produce white
lighting. Nevertheless this method is particularly interesting in many applications because of the flexibilityof mixing different colors,
[55] and, in principle,this mechanism also has higher quantum efficiency in producing white.

There are several types of multi-colored white LEDs: di-, tri-, and tetrachromatic white LEDs. Several key factors that play among these different approaches include color stability, color rendering capability, and luminous efficacy. Often higher efficiency will mean lower color rendering, presenting a trade off between the luminous efficiency and color rendering. For example, the dichromatic white LEDs have the best luminous efficacy (120 lm/W), but the lowest color rendering capability. Conversely, although tetrachromatic white LEDs have excellent color rendering capability, they often have poor luminous efficiency. Trichromatic white LEDs are in between, having both good luminous efficacy (>70 lm/W) and fair color rendering capability.

What multi-color LEDs offer is not merely another solution of producing white light, but is a whole new technique of producing light of different colors. In principle, most perceivable colors can be produced by mixing different amounts of three primary colors, and this makes it possible to produce precise dynamic color control as well. As more effort is devoted to investigating this technique, multi-color LEDs should have profound influence on the fundamental method which we use to produce and control light color. However, before this type of LED can truly play a role on the market, several technical problems need to be solved. These certainly include that this type of LED’s emission power decays exponentially with increasing temperature,[56] resulting in a substantial change in color stability. Such problems are not acceptable for industrial usage. Therefore, many new package designs aimed at solving this problem have been proposed and their results are now being reproduced by researchers and scientists.
