This is my 17th LED sign and different than all the rest of the ones I own.This one uses COB LED s rather than more common SMD LED s.COB stands for Chip On Board and SMD stands for Surface Mounted Device.Long story short, the COB chips in this sign appear appear to be bright White and you can see each individual LED through the pink part of the LED sign.I prefer an even glow,which is what I m used to seeing with SMD LEDs.Although,I have to say,the sign is very well made.I like that the white protected coating was left on both sides of the side to help keep it from being scratched. The corners were lifted up so I could easily peel off the coating. The power cord is nice and thick and the plug is Very nice compared to my other signs.The on off switch is nice but I prefer having a dimmer as an option.Overall it is a very well made sign.I just don't like each individual LED showing through when it is turned on.Please see my photos. They ll give you an idea but don t show nearly how much the LEDs shine through the diffuser.
