Glow Brick

Glow-in-the-dark lightbulb encased in resin.

• Recharge in light during day time to activate the subtle, tranquil glow at night - no power needed!
• The technical term for glow-in-the-dark is 'photoluminescence' – the process by which energy is absorbed by a substance and released relatively slowly in the form of light.
• The surface of the Glow Brick is polished to give a jewel-like effect.
