ERVAN is a privately-owned lighting company, and has been providing high-quality products such as LED High Bay, LED Tri-proof Light, LED Tube, LED Panel, and excellent customer service for more than 15 years, since 2002. We are a Shenzhen-based manufacturer, not only offer OEM & ODM service, but use 15 years experience and expertise to continually improve the service that we offer, to ensure that we add more value to clients who choose ERVAN products. One important survival rule for an enterprise that we have identified over years is the requirement for instantly available products that are high quality first and reasonably priced second. To meet this rule, we enlarged our warehouse size and increased more facilities that enables us to hold high stock levels of most of our energy-efficient products. Delivery is no longer the obstacle between our cooperation.
