Anti-collison
SMD lamp is easily to be damage when it is hit, while COB will not be like that

Water-proof/humid-proof
COB screen can be wiped with rag when it is splashed, while SMD can't be
done like that.

Dust-proof/anti-oxidation
COB got a good dust-proof performance, while SMD doesn't get that.

High refresh
perfect details, no flash for photographing.

Light and thin design
10.5kg/cabinet

neat appearance
power and signal cord is buit-in the cabinet.

fast installation
60 cabinets can be mounted in an hour.
