The SolarBrick is a self-contained premium solar powered lighting device for traffic and decorative uses. It is waterproof, easy to install and can be driven over by vehicles. The SolarBrick is available in 6 attractive colours. It comes in 2 standard sizes, 8x8" and 8x4". Rechargeable batteries currently used in solar devices need repeated battery replacement every 2-3 years at best. They also have a narrow working temperature range. Ultracapacitors enable SolarBrick lighting devices to be used in any environment without maintenance for more than 10 years and have a wide operating temperature range of -40°~75°C (-40°~167°F). The SolarBrick uses a patented ultracapacitor, the EnergyCache, to store its charge. During the day, solar energy is converted to electricity through the solar cells and stored in the ultracapacitor. At night, the inviting soft glow from the light emitting diode (LED) is automatically turned on. Full charge takes 1 hour under direct sunlight and 6-8 hours under shade.
