The SNITCH 1.5W LED Handrail Lights are marine grade quality, covered with a three-year warranty. Designed for architectural lighting and for safe movement in public spaces. These LED recessed fittings have a stainless steel (316L) front face protecting them from water including saltwater and general corrosion. Suitable for tubes with a diameter of 48-60mm, and tube wall thickness 1-2mm. Asymmetrical 30°x60°optic, with spring for fast recessed installation. The ideal spacing is 600mm apart, to avoid a patchy light spread.
