The RL 70 LE is a 70-mm tube luminaire that continues the legacy of Waldmann’s trusted machine lighting solutions. As the classic model in its category, it retains the proven structural design that has delivered maximum reliability for decades. What sets the RL 70 LE apart is its modern LED integration, enabling continuous operation without the need for lamp replacement. Its length options are tailored for seamless 1:1 replacement of conventional tube luminaires, maintaining compatibility and simplifying upgrades.
Visually, the RL 70 LE stays true to its roots. The design has stood the test of time, with a form that not only defines function but also offers lasting appeal. Rather than altering its recognizable aesthetic, the focus has been on broadening its versatility, allowing this reliable light source to serve more locations and applications with uncompromised performance.
From a design standpoint, the RL 70 LE embodies functionality. Its longitudinal shape has been optimized to ensure easy retrofitting into existing setups. This classic silhouette has remained unchanged because of its effectiveness in industrial environments.
The luminaire is built for durability, with materials tailored to specific working conditions. It is available with a borosilicate glass tube for oily and wet environments, an acrylic tube designed to withstand powerful water jets, and a polycarbonate version suitable for areas in close proximity to food products. These material options ensure high resistance and longevity even under demanding circumstances.
Performance-wise, the RL 70 LE combines cutting-edge LED technology with specialized light-forming foil to deliver bright, homogeneous, and glare-free illumination. Its wide beam angle and smooth transitions make it ideal for ensuring optimum visibility near machine tools and workstations. With a rated service life exceeding 50,000 hours (L70), it is designed for maintenance-free, nonstop operation.
The luminaire also offers flexible connection options. Originally available with machine voltage (22–26 V), it is now offered in a 230 V mains voltage version. By removing the integrated ballast, this variant can effectively illuminate spaces that are farther from machine tools while maintaining consistent, glare-free lighting.
This expanded offering now includes up to 48 product variants, combining different voltages and materials to cover a broad spectrum of applications. The RL 70 LE is ideally suited for diverse industrial environments, including textile, printing, and timber machinery, as well as packaging, production, and food processing systems.
Technically, the RL 70 LE delivers a neutral white color temperature of 5,000 K with a color rendering index of Ra > 80. It features Light Forming Technology for glare-free performance and is rated IP67 with protection class III. The fixture connects via cable gland and can be accessorized with various brackets and operating devices for integration into different power supply setups.
