Luminox Light Technology VS Super LumiNova

Luminox Light Technology VS Super LumiNova

Some of you may be confused about the difference in the use of Luminox Light Technology (LLT) and Super LumiNova in Luminox timepieces. In order to have a clear understanding of the difference between these two, we must know what are they individually. 

Luminox Light Technology

LLT (Luminox Light Technology) is a light source, able to glow for years without
need of recharging. It consists of a glass tube of borosilicate glass, which is internally coated with a phosphor powder and filled with tritium gas. Phosphorus is known as a luminescent material which gets its glowing when exposed to UV-light. The same effect appears when phosphor powder and tritium gas are isolated in a glass tube. 

Super LumiNova

Super-LumiNova® - High Performance Phosphorescent Pigments - also called "photo-luminescent" or "afterglow" pigments, these are the most common used, non-radioactive and non-toxic alternative for illuminating markings on timepiece dials and hands in the dark. Selected grades of new chemical compositions have up to 100 times better brightness than previous zinc sulphide materials. These pigments operate like a light battery. After sufficient activation by sunlight or artificial light, they glow in the dark for many hours. Larger markings guarantee full legibility for the whole night. 

Therefore, if the illumination of a dial or hands uses Super-LumiNova, we talk about night glow. The watch needs to be exposed to daylight or artificial light for recharging the fluorescent material. On the other hand, Patented system (LLT) uses glass tubes filled with phosphor powder and tritium gas. This tubes glow permanently for up to 25 years with absolutely no recharging necessary. Also, Super LumiNova's activation and subsequent light emission process can be repeated again and again, and the material does not suffer any ageing, while LLT loses intensity over the years.
