Self Powered Safety Products Limited, known as SP2, is a British company dedicated to the development and supply of self-illuminating markers and tactical devices for those whose activities are carried out at night. Our goal is to make night operation and navigation safer, easier and more efficient. Our radioluminescent devices do not require any charging or switching. Unlike photoluminescent and chemiluminescent devices, they will continue to glow for many years, even during prolonged periods of complete darkness. No external power supply is needed so there is no need to check and replace batteries or maintain a mains power supply. Nor is any maintenance required. Therefore, the cost of ownership for users is very competitive. Our range of products extends from simple Kit Markers through Secure Torches and Prismatic Compasses to Fire Safety Signs. Each product incorporates one or more self-luminous trigalight® light sources, enabling users to use the device quickly and easily in the dark.
