Price says a lot about brightness
Whether online or in retail: the price of a glow pigment ultimately says a good deal about its performance. The cheaper the material, the weaker and shorter it usually glows. A conspicuously low price is therefore more of a warning sign than a bargain – at the latest when the finished product disappoints in the dark.
Our approach: the best possible performance at a sensible cost
LUMENTIFY specialises in powerful, long-lasting glow pigments that have proven themselves in industrial use and in end products, both in experience and technically. In brightness and quality we deliberately position ourselves in the upper range – aiming for the best possible performance at a sensible material cost, without the price of the very top special materials.
Even more is possible: around 5 % additional afterglow brightness can be achieved with special materials – but then it becomes considerably more expensive. You can ask us about that too.
Criteria for your purchasing
| Criterion | What to look for |
|---|---|
| Material | europium/dysprosium-doped strontium aluminate – the material for a long-lasting afterglow |
| Surface | SiO₂ coating for hydrolysis resistance, important in damp environments and water-based systems |
| Glow colour | The brightest pigments are untinted (natural green, blue-green, blue) and have a light, whitish daylight colour. Strong daylight colours indicate tinting and therefore less brightness. |
| Particle size | a clear figure in µm that suits the application – coarser glows brighter, finer processes better |
| Afterglow duration | more than 10 hours in total darkness for the bright pigments |
| Service life | low ageing – very little with our pigments |
| Documentation | a complete, current safety data sheet in your language – if it is missing or incomplete, that is a warning sign |
| Sampling | samples for your own test – a reputable supplier lets you test the material in your own system |
The best test: in your own system
Data sheets and photos are a start, but no substitute for a comparison in your application. Charge samples from different suppliers for the same time with the same light source and look at them together in the dark – right after switching off and again after one or two hours. Then you will see which pigment delivers what it promises.
In shortLook at material, daylight colour, particle size and documentation – and be wary of conspicuously cheap offers. In the end, the test in your own system decides.
