LED High Bay Light (ST-21-37W660/UB)
Our LED high bay ight advantages Introduction:
1. Twice total light output:
The most important point of our super bright low LED street light is not watt but the total light output which is as twice as much of high power LED street light when the watt are the same. Ours can be145 ~160luminous/watt however others can only be up to 80 luminous/watt. If you plan to buy 56W of high power LED street light, then 28W of ours is enough for your need. Please never use the same watt of high power LED street light to compare the price with our low power LED street lights. Please use 56W of high power LED street light with our 28W, then you will find we are the lowest. So We are the most cost effective.
2. Return On Investment is half time shorter:
Comparing with high power LED street lights, our low power LED street is much less energy consumption. So if your application is powered by solar or solar-wind energy, you need half solar panel, half battery, half power of wind turbine And controller, which largely reduce the total cost and greatly enable you much more competitive, as the total price of all company is based on the usage of every components. So the return on investment is half time shorter than your choosing high power LED street light.
3. Much less heat generation:
So the performance is much stable and much less lighting decay, which will surely prolong the life span.
4. Inclination adjustable:
We design a special elbow which enable you to adjust the inclination by every 5ºC
5. 6000hrs luminous Maintenance 94.26%
6. 20%-40% cost of market sales price.
