Great features 

1) Certification,All the series LED high bay lights are CE,ETL ,PSE certified. 

2) Full range wattage options: 30W to 240W, replacing 150W,  250W, 400W and even 1000W HID 

3) LED chips,Bridgelux and Citizen chips for your option. The system efficacy is up to 85lm/W. 

4) Very big heat sink using high quality aluminum material.The diameter is up to 260mm to ensure the good heat disspation in  horizontal and  longitudinal .

5) Reliable driver.

LED chips itself could last very long with a good heat sink. But the driver may not. The component in the driver we need to worry about is the electrolytic capacitor. The cap only can last 2000 to 3000 hours at the temperature 105 ℃. But it can last 40,000 to 50,000 hours when the temperature is at 60 ℃. The electrolytic capacitor in our driver is working at 60 ℃, when the ambient temperature is 27℃.

6) Maintenance. The driver could be pl ed in and out easily. Only a few screws, no soldering point, while lots of high bays in the market is hard to replace the driver. So if the driver fails we can replace the new driver to you in three years for free including shipping fee. No risk for you.
