Megalight Systems Oy operating in Finland has been manufacturing and developing its own worksite lighting systems for over 15 years now. We asked professionals who use lighting equipment in their work, what do they expect from a good lighting system. Based on the results of this enquiry we developed the versatile Megalight System – the portable lighting equipment and extension cord system, intended for professional use. 16 A socket for electrical devices or for chaining lamps into a system, a high-quality 10 m extension cable, handy suspension and attachment solutions as well as replaceable dirt protectors with or without reflectors represent solutions that are highly appreciated by professionals.
