About this file
This document is a product specification sheet for the ERCO Castor Bollard luminaire, model 35736.023, a floor washlight fixture designed for outdoor architectural lighting applications.
The Castor Bollard luminaire features an 8.1W LED module producing 1036 lumens at 3000K warm white color temperature with 0-10V dimmability capabilities. The fixture has a luminous flux output of 198 lumens, connected load of 9.8W, and luminaire efficacy of 20 lumens per watt. The housing comprises a corrosion-resistant aluminum bollard profile with double powder-coated, optimized surfaces to reduce dirt accumulation, combined with corrosion-resistant cast aluminum upper cover and base plate. The anti-glare cone features 180-degree light guidance via an optical polymer ring and is glare-free above the light aperture. The luminaire is rated for wet locations (IP65) with a maximum wind load area of 0.058 square meters and weighs 3.51 kilograms. Technical specifications include a housing temperature of 56°C, color rendering index (CRI) of 92, lumen maintenance L90 greater than 100,000 hours, LED failure rate of 0.1% beyond 50,000 hours, and control gear rated for 120V/277V at 60Hz. The document also specifies melanopic light effect data, maintenance factors under various cleaning and ambient condition scenarios, and references compliance with international standards including IEC 60598, IEC 62031, IEC 62471, and UL standards. Three mounting accessories are available separately: mounting plate (33982.000), ground socket (33975.000), and concrete anchor (33979.000).
