Mcnett Nitestik

Mcnett Nitestik. The Nitestik Safety Marker is stronger, slicker and cooler than ever. We challenge anyone not to find a use for one! Using Photoluminescent pigment technology, the Nitestik Safety Marker is highly visible even in total darkness. Designed for marking equipment and personal property, it is useful to anything you might wish to locate in the dark. Vibrant coloured and acrylic housed the amazing Nitestik uses state-of-the-art technology that is environmentally friendly. Inside each Nitestik is a rare earth-activated alkali earth aluminate-silicate, that can continuously give off light for over 12 hours in darkness by absorption of various visible light. This new age pigment will charge under light, then discharge in darkness 365 days of the year, for upto 10 years. No Batteries......Lasts up to 10 years......Thats pretty impressive stuff!FEATURES: • Glows for upto 10 years!• Glows in bright green for over 12 hours in darkness• Visibility 20 metres• Waterproof to 30 metres• Environmentally friendly• Requires no power• Tintet acrylic UV-protectet housing• Housing available in six different colours: Crystal Green, Ice Blue, Cool Pink, Mellow Yellow, Royal Purple and Vibrant Orange• Length: 51mm• Width: 10mm• Ring: 23mmCHARACTERISTICS OF PRODUCT:• Enviromentally Friendly• The wavelength range of excited lights is broad and the light sources are easily and conveniently obtained• After absorbing various visible lights, it can glow for more than twelve hours in the dark• Excellent physical and chemical properties. The product can be utilized in the outdoors and bad conditions, which have outstanding anti-Ultraviolet properties• Extremely long lifetime. More than ten years.• It can absorb, Store and emit visible light repeatedly.Technology:PHOTOLUMINESCENCE EXPLAINED:- Luminescence occurs if a material exposed to a source of excitation absorbs energy, and them emits that energy as a visible light. The energy can be derived from a number of sources including a light bulb, headlight, fluorescent light (any artificial light) and under sunlight. The stronger the light source, the quicker the charging process.- Photoluminescence also occurs by electromagnetic excitation and the material also emits while the energy source is present. But with photoluminescence the relaxation of the electgron back to the ground state and subsequent emission of photons of light continues long after the excitation source is removed. This is termed the "afterglow".- These rare earth-activated alkali earth aluminate-silicate photoluminescent pigments are not like glow sticks that only last for one time. This occurs because it is not a chemical process but a modification of a crystal. Photoluminescent pigment does not lose its effectiveness over time. This new age pigment will charge under light, then discharge in darkness 365 days of the year, for upto 10 years. INTRODUCTION PHOTOLUMINESCENT:Photoluminescent pigment is a rare-earth activated alkali earth aluminate-silicate. The main characteristic of this material is the particular structure of its crystal with the strong capacity of absorbing storing emitting light. PHOTOLUMINESCENT PIGMENT INDEX:The photoluminescent pigment is made of alkaline earth aluminate. The pigments appearance colour is light yellow-green and its glowing colours are yellow and green. These give the strongest glow as seen from the chromacity Diagram below
