20 PCS ST43 solar lights were installed on the wall of a building in Malta. Adopting side-entry mounting, ST43 were successfully installed on the wall. As an all-in-one solar LED light, ST43 also contributed to easier installation and lower operating costs. No wiring or extra electricity costs were needed for illumination at night. With professional optics, ST43 directed the light on the ground and illuminated the building surroundings without trespassing the sky. The bright light greatly improved safety around the building and avoided accident.
