The Crane Master Series
An LED floodlighting solution designed for applications requiring high performance and high durability. Featuring a full AISI 316 stainless steel body built to resist the harshest environments. The Midstream Crane Master Series provides LED Crane floodlights to ensure maintenance-free operation for a range of critical applications in maritime environments.
Features and benefits of the Crane Master Series:
- Heavy Duty LED floodlights built to resist the harshest environments and for applications needing high performance and high durability.
- A low weight design and compact size allows for an easy to install solution.
- Designed with a wide range of optics to provide a solution that maximises safety across all areas and allows for the provision of a tailor-made crane lighting layout for your environment, using the optimum choice of optics to reduce glare, increase uniformity and avoid any dark spots on the ground.
- Manufactured with Midstreams proprietary Asymmetric optic that guarantees a wide coverage of luminance levels for improved obstacle recognition and the light emission allows light to cover an area four times larger than currently achievable with traditional symmetric optics, removing the need for additional front-facing floodlights for example on cranes, resulting in a low glare installation.
- Manufactured with 316 stainless steel to resist corrosion in harsh, saline environments.
- Certified IP 67 for highest level of ingress protection.
- Tested on STS & RTG Cranes.
- Tested for Salt spray for 1000h according to ASTM B117 and for Vibrations up to 6G and 100.000 Cycles
according to ANSI C136.31-2010. - UL certified and DLC listed (US Version)

Frequently Asked Questions - Crane Master Series
What makes the Crane Master Series suitable for harsh maritime environments?
We manufacture the Crane Master Series using full AISI 316 stainless steel to ensure exceptional resistance to corrosion in harsh maritime environments. Our luminaires are tested for prolonged salt spray exposure and high vibration levels, giving ports and terminals confidence that the system will perform reliably in demanding coastal conditions.
How does the asymmetric optic technology reduce glare compared to traditional crane lighting?
We use proprietary asymmetric optics to distribute light precisely where it is needed. Unlike traditional symmetric floodlights, our optics spread illumination evenly across crane paths and operational areas, improving visibility while significantly reducing glare for operators and ground staff.
What certifications does the Crane Master Series meet for port and maritime applications?
Our Crane Master Series is IP67 rated for protection against dust and water ingress. We test our fittings for up to 1000 hours of salt spray resistance in accordance with ASTM B117 and for vibration resilience up to 6G under ANSI C136.31. For the US market, the range is UL certified and DLC listed.
How long does installation typically take for STS and RTG cranes?
We design the Crane Master Series to be compact and lightweight, making installation straightforward on both STS and RTG cranes. Installation time varies depending on crane configuration and site conditions, but our design supports efficient mounting with minimal operational disruption.
What maintenance schedule is recommended for optimal performance?
We engineer the Crane Master Series to minimise ongoing maintenance. We recommend regular visual inspections and periodic cleaning of the optical surfaces to maintain peak performance. Full installation and maintenance guidance is provided with each system.
How does the 316 stainless steel construction compare to aluminium alternatives in salt spray environments?
We choose AISI 316 stainless steel because it offers significantly greater resistance to corrosion in salt-laden environments than many aluminium alternatives. This helps extend product lifespan, maintain structural integrity and reduce long-term replacement costs in demanding maritime applications.
