Q1   What is photoluminescence?

    
Simply put, it's "Glow-in-the-Dark" technology which now utilises far superior materials and expertise to
     out-perform the old-fashioned 'stars-on-the-ceiling' and gimmicky toys from decades ago.


       From Wikipedia: Photoluminescence is a process in which a substance absorbs photons (units of light)
     and then re-radiates photons.  The simplest photoluminescent processes are resonant radiations in
     which a photon of a particular wavelength is absorbed and an equivalent photon is immediately emitted.


    
This process involves no significant internal energy transitions of the chemical substrate between
     absorption and emission and is extremely fast, of the order of 10 nanoseconds.



Q2   What is so Unique about the Lumenite Light Sleeve?

Photoluminescent products such as signs, arrows, stair strips and markers are strong enough to 'be seen', providing visual guidance in what might otherwise be a dark environment.  A sign above a door in the distance will guide you in the direction of the exit, but unseen obstacles between you and that exit may delay your evacuation.

Lumenite Light Sleeves encase fluorescent lamps and with clever design characteristics and very close proximity to the light source charging them, when called upon they emit usable light onto walls, floors and pathway obstructions in the near vicinity, eg desks, chairs, hospital beds, machines, etc.

The photometric curve of the light output emulates that of the lamp and fixture combination as it was designed by the manufacturer.



Q3
 
How long does the 'afterglow' effect last?

      The human eye can see down to levels of 0.32 milli-candelas/sq metre.  The time it takes for the decay
      in afterglow to reach that level depends on how well the material was charged before the light source
      was removed, but assuming it was fully charged it can take
in excess of 40 hours.

      When referring to the light being 'projected' onto pathway obstructions by the
Lumenite Light Sleeve
      for continuous visibility, the determining factors include the size of the area, the number of sleeves
      installed, their height and proximity to the obstacles, how reflective the surfaces of objects are, etc. 
     
      However, provided sufficient sleeves are installed there should be adequate light for safe movement and
      egress for
several hours once the eye has adapted to the low-light conditions.

                         



Q4 
How long will the product last?

      The chemical that provides the afterglow effect is strontium alluminate which is a rare earth metal and
      will last indefinitely, so the substrate that it goes into will determine the lifespan of the product.

     
      The Lumenite Light Sleeve uses polypropylene as its base material, and due to the close proximity of
      the Light Sleeve to the fluorescent lamp - which is emitting ultra-violet light, would be expected to
      breakdown and become brittle quite quickly.  To overcome this, our Light Sleeve formula incorporates UV
      inhibitors to provide a life expectancy of at least 7 - 10 years.  The number of hours per day, per week,
      per year that the flourescent lamp is on will have a significant bearing on the life of the Light Sleeve
      but even with 24/7 usage they will last for several years.

      Other products such as the Lumenite Stair Edge Strip are unlikely to be as affected by ultraviolet light
      as the Light Sleeve because they generally don't receive the same amount of exposure to it.  As a result
      their life expectancy is determined by other factors such as degree and harshness of foot-traffic and the
      environment in which they are located.   


Q5   Who else is using them?

       In the United States alone we can boast sales to the White House, the C.I.A., U.S.Army, Airforce
      and Navy, Coastguard, and many institutions, hospitals and universities plus inumerable companies
      and corporations.


Q6  
Are they Radioactive or Toxic?

       No, they are quite safe.


Q7   What approvals do you have for the light sleeve?

      There are no standards for photoluminescent light sleeves so there is nothing to test or certify it
      against.  Basically, it’s an inert object, and a unique one.

                Inert –adjective
                1. having no inherent power of action, motion, or resistance
                2. Chemistry: having little or no ability to react chemically

      There are no inherent dangers associated with it. The MSDS show the lack of toxicity and radioactivity,
      melt points etc so there is nothing to suggest any safety issues, but if you have anything specific and
      justifiable that you want proven in a laboratory we’d be happy to oblige.

 
Q8  How do I dispose of the product at the end of it's life cycle?

  
   The sleeve is not intended for disposal as it has a lifespan of many years and can be used repeatedly;
      just remove the expired florescent lamp from within the light sleeve, replace it with a new lamp and refit
      to the lighting fixture.  Eventually it may become brittle to the point where it is no longer serviceable.
     
     
When this happens you may return it to us if you so cho
ose because we can pelletize it and reuse the
      base materials, but it is not harmful to the environment so there are no special instructions for disposal.
 

      To explain further, the substrate is polypropylene (although we reserve the right to change this) which
      is blended with strontium alluminate to achieve the afterglow effect which projects usable light onto
      nearby obstacles and obstructions. This is a rare earth metal which is non-toxic and non-radioactive.

      Other chemicals in our proprietary blend include U.V. stabilisers, binding agents etc., none of which carry
      any restrictions on disposal.


Q9   Does the Light Sleeve act as a glass containment device?

       Yes, although it is not certified as such. Should a lamp break inside the Light Sleeve, simply remove one
      of the friction-fit end caps to empty out the broken glass, then slide a new fluorescent lamp into the
      Light Sleeve and refit to the fixture. No need to dispose of the light sleeve at this time.


Q10  Can I have free samples?

       Probably the most common question of all and we would not be in business today if we gave away our
       products to everyone that asks.  But if you have a story to tell, we'll listen.
