Lumi-Plugin – the innovative downlight designed to discreetly hold multiple plugins, including essential fire safety systems – is partnering with iMist, one of the UK’s foremost suppliers of high-pressure water mist fire suppression systems to create a new plugin; one that uses less water to supress a fire, takes less time to install and removes unsightly clutter from the ceiling.

A live fire test was recently conducted at the Fire Protection Association’s Annex C laboratory in Gloucestershire recently to put this new joint venture through its paces.

A Lumi-Plugin LED downlight was installed with an iMist nozzle, mounted on the company’s standard stainless steel flexible hose and fixed above a plasterboard ceiling. A fire fuel load was then ignited beneath the nozzle, with the heat causing the bulb in the nozzle to burst and activating the iMist high-pressure water mist system. For 30 minutes, fine water mist particles were discharged at high pressure while the fire was adjusted to a variety of heights and positions and the temperatures in the test cell were measured by thermocouples. 

A safe and successful result was reported. The test demonstrated that at no point were any of the Annex C temperature limits breached and the fire was successfully suppressed. It also showed that that the Lumi-Plugin light adapter was operating correctly before, during and after the live fire test was conducted and sustained no visible damage during the test.  

Alex Pollard, operations director of iMist, commented: “At a time when fire safety is a major concern both within the housing sector and the public at large, it’s vital that forward-thinking companies like Lumi-Plugin and iMist come together and combine their technology to offer new fire safety solutions. This is a ground-breaking test which we believe is the first time that a high-pressure water mist system has been successfully incorporated into a downlight. This Lumi-Plugin option combines the water and cost-saving benefits of our fire suppression system in an ingenious application; it is easy and fast to install – and doesn’t spoil the look of a room.”

Ben Bishop, operations director of Lumi-Plugin explained: “Over the last 6 years, our revolutionary products have become known for their fire safety and energy-saving innovation while uncluttering ceilings and creating streamlined interiors. As part of our ongoing R&D programme, we are continuing to develop additional safety features. We are pleased to be partnering with iMist to offer our customers this latest plugin – it is an important part of our mission to enable them to create safer and smarter properties.”
