Yes , I agree . many chinese lights have a poor repuation for durability , but almost all lights products are made in China , so there are good quality ones and there are worse ones .
Our qualuty control is our led chips , drivers and heat sink . when we develop our led grow lights , we are always trying to make the better quality as possible as we can , but also need to offer the good price . Philips led grow bar must be great quality , if comparing with our led grow bar( CREE LED chips , UL drivers ) . Hard to tell they are better than ours . We have 3 years warranty . People aren't willing to spend 3 years to check which one is better quality . Only time test the quality .
