The smallest of our IP67 sealed range of panel indicators, recently introduced on our website, are the 5.0mm mounting 603 and 604 Series professional LED indicators.

Marl's precision engineering has enabled this small indicator to contain the same high intensity LED technology, reverse protection diode, ingress protection and outstanding quality.

The 603 is designed with a colour diffused lens assembly for general applications and the 604 series is specifically designed with a smoked lens assembly for excellent on/off contrast ratio in high sunlight applications.

This smaller range of panel indicators is available in a range of LED colours, and voltage options.

Whilst attractions like award-winning Muncaster Castle in the England’s Lake District overflow with visitors in the summer season, extending that popularity as the nights draw in is at the same time a challenge and a commercial necessity for operators.

Country houses like Muncaster have a great history of pioneering new technology. Peter Frost-Pennington, whose family have occupied the castle for 800 years, was thus maintaining a proud tradition when he turned to Marl for innovative LED lighting solutions that would not only make access safe and practical for visitors, but could become an attraction in themselves.

As he developed and extended the Darkest Muncaster concept, Frost-Pennington identified Marl as a source of LED lighting, suitable for outdoor use that would match the light output of his existing units but using much lower energy – and with bulb life of 70,000 to 100,000 hours. Peter Frost-Pennington has added Marl LED lamps extensively into the Ghyll Show. Aztec 5W light fittings were installed in as many windows as possible on that side of the Castle, replacing existing 50W fittings. This gives a 90% reduction in energy use.
