We offer the largest selection of professional, commercial grade, solar powered LED sign lights in the world. Solar Illuminations specialises in sign lighting systems and we have systems suitable for any sized sign, internally or externally lit. Many signs in the UK are installed where there is no electricity nearby. If a sign or outdoor advertising is not lit up at night time then you lose 50% of exposure every 24 hours. For business owners, it's very important to have signage lit during the hours of darkness. Many signs are located some distance away from a mains power supply. Therefore using a solar powered system is an ideal solution to this problem and is also a 'green' alternative to using mains power. All our sign lights are easy to install, no electrician required!
