SMALL PHOSPHORESCENT PEBBLES

Phosphorescent stones and pebbles

Our little phosphorescent stones have the natural capacity to emit light in darkness. They exist in 3 colours of glow.

The phosphorescent effect can last all night long, after the stones have been exposed to light a few tens of minutes.

This decorative effect doesn't need electricity and requires a minimum of care. The photoluminescence lifetime lasts a great many years (more than 20 years).

Spotlight on photoluminescence

Photoluminescent products store all types of light energy (particularly sunlight, white light and UV light) and can be fully recharged in a matter of minutes
they then release this energy in the form of phosphorescence
with a luminance level expressed in microcandelas per square metre: mcd/m² (not in lux)
and with a afterglow expressed in minutes until complete extinction (0.32 mcd/m²),

the luminance level depends mainly on the colours
green colours are the most effective, followed by turquoise and then blue
the same applies to the afterglow

green: the whole night
turquoise: most of the night
blue: half the night

► It is important to inform customers that photoluminescent products are effective and therefore visible in complete or near-complete darkness. They are therefore not effective in an urban environment where there is street lighting. The same applies in an area without street lighting but with a full moon.

Storage instructions
These products are not sensitive to UV light,
temperature or humidity

Durability:
the fragments are made of glass, making them extremely durable outdoors in all weather conditions
the stones are made of plastic, so they may yellow slightly over the years

Their possibilities are without limit, they can glow indoors or outdoors, as long as there is enough obscurity: gardens, bedrooms, ponds, pools, fountains,  aquariums, vases...

These little objects are harmless, non-radioactive and made of plastic.

Precautions: Keep them out of small children's reach, as the stones are quite little (2 to 3 cm)

Depending of the colours, the phosphorescent effect is more or less powerful: green is the strongest colour, and by decreasing order, blue green, blue.
