Q: Do you have some suggestions on how to choose a good LED corn lamp vendor?
A: To choose a stable LED corn lamp vendor is very important if your company decide to promote these lamps. Because these lamps usually installed in outdoor with 10-30 feet height, it means the installation cost is very high. So please ensure the lamp quality is very good, otherwise, your company will lose lots of money on later maintenance. All in all, you should put "quality first, prices second."
