Redoubt 100: Redoubt 100 is a maintenance pit luminaire, specifically designed to achieve the recommended illuminance and uniformity levels for heavy duty pits within rail maintenance facilities. Redoubt 100 has been constructed in a way that allows for it to be wall mounted between stanchions to provide uniform lighting for both the underside of vehicles and the pit floor by incorporating separate upward and downward illumination. Upward illumination is designed to meet the requirements for task lighting whereas downward illumination designed for circulation and emergency. Redoubt 90 has been carefully designed to minimise glare, by restricting the output based on the illuminous surface area, in order to comply with BS-EN 12464-1 (1000lm per 300cm²). Redoubt 100 has been tested to several ingress protection ratings (IP66, IP69 and IP69K) to ensure cleaning at high pressure and temperature including jet washing. Rated to IK16 (150 joules of energy) ensuring a high level of impact resistance. Marine grade stainless steel body incorporates a flush clear polycarbonate diffuser with the electronic control gear on a removable tray for ease of maintenance. Efficacy of >118 lm/ W. Colour Temperature:4000K CRI:>80 LED Lifetime L70B10>72,000h at 25oC ambient. Driver Lifetime up to 100,000h at 25oC ambient.
