Does JD design its own products?
Yes. JD designs and assembles our own products. We have professional engineers,and some of them had designed the world famous lighting.

What kind of LED does JD usually use for LED lamps?
For high-power LED lamps, we mainly use Epistar and Bridgelux.

Why high quality LED lamps more expensive?
Energy-saving and long life span are the strong points of LED lamps. Energy-saving is the nature of LED, while durable is determined by light attenuation control. The first key factor of controlling light attenuation is LED. High quality LED with high price and  less light decay, while inferior LED with low price and  quick light decay. The second factor is constant current driver.
LED lamp are very sensitive ,for only constant current driver can control the heat of LED to achieving the light maintenance. But high quality LED constant current driver is much expensive. These three main factors determined  the quality of LED lamps and  the price. That"s so called high quality high price, low price quick light decay.

Are bulbs with more leds brighter than bulbs with less?
The quantity of leds is not the determining factor of bulb brightness. Different types of leds vary greatly in size and light output. The most accurate indicators of the brightness of LED bulbs are the measured lumens or lux. Lumens measure the total amount of light output from a bulb (how bright it is). Lux measures how bright the light is on a surface at a specified distance normally 1m.
