These were usually designed for businesses or hotels where the older neon types were already in place. The more common these days is the CLASS LED type, as it simply requires a message be sent, the same type as caller ID. Before you become too deeply invested be certain that the neon lamp will work with whatever source you are using.Yeah it will be interesting to see if the Grandstream HT's do really pump 90V or whatever out to light a real neon.
