Neon and Cold Cathode signage is suitable for high impact applications when you really need to get your message across. Neon glass can be produced in a wide range of colours and can include flashing units to further enhance the effect. Neon is often used to internally illuminate letters and logos though is slowly being replaced by low voltage Led units in many applications. For internal applications the glass is generally enclosed within an acrylic box for neatness and safety, these can usually be wall mounted or suspended for window locations.
For super bright, highly visible and cost effective designs, neon is still No.1 option and will always retain its niche in the market.
