The Nordlux Tin Spear Light can be used to create dazzling visual effects in your garden or commercial outdoor space. It is a versatile light that can be used in a number of different ways - it looks great fitted below trees, in flower beds, around water features, along pathways and driveways and around outdoor social areas. The beams are easy to adjust to create the desired visual effect.This stainless steel light must be treated with acid free oil (which is included) 3-4 times a year. We do not recommend to install lighting made of stainless steel in an aggressive (e.g. coastal) environment.
