Q1 How do you evaluate surface mounted cob led downlight 30W?
Lumen output is only part of the story and can be misleading. To fully evaluate an LED product one needs to review the overall system efficiency,optical control, thermal management of the LEDs, and know at what point in time the fixture will reach 30 percent lumen depreciation. Products with good optical efficiency and thermal management will be able to deliver more lumens, on average, than traditional HID products.
Q2 How long will my LED Light last?
LEDS last up to 8 times longer than CFL and Incandescent lamps and you can expect at least 50,000 hours of use from your LED Lamp.
Q3 How should i choose the color temperature ?
3000K, warm and appealing, for leisure atmosphere and accent lighting
4000K, natural effect, ideal application on public places.
6000K, bright and efficient, for pleasant and healthy office environment.
LED Downlight is popular for store,hotel,shopping malls,gellery, museum,office
