The ILP are pleased to announce the first speakers for the Professional Lighting Summit taking place on 13 & 14 June at The Oxford Belfry, Nr Thame.

This page will be updated regularly, as more speakers are in the process of being organised and confirmed.


Gary Thorne, Street Lighting Manager, Ringway Infrastructure ServicesStreet lighting’s Plus Ones

Street lighting is not just lights: it includes everything else that is connected into or maintained as part of the street lighting contract. Street lighting engineers are often not consulted but then landed with issues caused by bus shelters, advertising free standing units, way finders, vehicle charging points and smart city systems. These items have been installed on the highway, either sub circuited from street lighting equipment or with a direct connection to the DNO. Without changing all street lighting furniture, how do we ensure that structures are secure? That electrically they are sound? That they are fit for purpose? Gary will share some worrying scenarios and ask ‘How can local authorities balance the needs of smart cities with safety and good practice requirements?’



The occurrences of light festivals in UK cities has grown exponentially in the last decade, yet little is known of their impact on participants’ and audiences’ lives; how the spatial landscape of their urban contexts shapes participants feelings and behaviours. Much has been studied of the impact of cultural festivals, how they may be central to our identification with place, however, investigation into light festivals has been minimal, therefore the research aims to address this gap, particularly focusing on a small event, where empirical evidence is lacking.                            

Utilising a case study of a small lantern procession in Ordsall, Salford, which started in 1994, Gail will analyse the 2018 festival, which marks a major anniversary for an inner-city community, whose landscape and sense of place is increasingly influenced by central and peripheral private housing developments. The research seeks to understand how this annual lantern procession deepens a sense of place for established residents and introduces the character of place to newer residents.


Steve Edwards BSc & Anthony Smith IEng FILP, Stainton Lighting Design ServicesNewport Bridge LED Feature Lighting

Newport Bridge is a striking structure and exceptional piece of architecture located in the North East of England linking Stockton-on-Tees with Middlesbrough. This historic vertical-lift bridge has a complex steel construction dominating the industrial skyline, each viewpoint offers something new but always imposing. A recent refurbishment provided the opportunity to illuminate its extraordinary design features, highlighting its scale and complexity whilst celebrating early 20th century British engineering.

The Grade II* listed structure offered many design challenges including non-invasive installation methods, but also minimising impact to the adjacent waterway, and other key stakeholders.

The case study for the recently installed LED feature lighting covers all aspects of the project from concept design, through trialling and demonstration, detailed lighting/electrical design into installation and final commissioning.

Stuart Beale BSc CEng MIET, Highways England & Allan Howard BEng(Hons) CEng FILP FSLL, WSP - Resolving a gap – Task visual acuity with short tunnels

A report on a recent project to improve the safety performance of short tunnels on and under the Strategic Road Network with regard to vulnerable road users and at the same time reduce crime and the fear of crime for non-motorised road users.

It is considered that there is a disjoint / void between BS5489-1 and BS5489-2 when it comes to the lighting assessment and hence application of artificial lighting within short tunnels.

Highways England commissioned WSP and University College London (UCL) to undertake a detailed research assessment of current UK and global short tunnel lighting practices with respect to such features. This included detailed surveys, investigations and research (such as using luminance imagery and eye tracking equipment to understand the users visual needs) of a range of existing short tunnels with the aim of publishing a report with recommendations to ensure that suitable user visual acuity is achieved.



The elephant in the street relates to the frequently discussed but little addressed topic of glare from LED exterior luminaires and how this affects the visual task through disability glare but in the case of wet road surfaces a loss of uniformity

Industry and user concern exists over the application of Threshold Increment assessment with respect to LED luminaires. Currently threshold increment is based upon traditional light sources which are comparatively large compared to the luminaire. The advent of LEDs with their much smaller size is raising concerns that although these seem to meet the threshold increment requirements, the installations often display a high level of disability glare.

So is the assessment approach right for LED external luminaires?



One change this year will be the technical committee’s update on the final day of the Summit, from 3-4pm.

The ILP is all about high-quality CPD and, if we want our members to have access to CPD and technical services as a core membership benefit, then we need to make that available to all our members, especially those up-and-coming within our industry. 

To that end, we want to encourage members and employers to send their younger staff to this session. To encourage this, the paid-for element of the Summit will therefore now finish before the technical committee reports and the technical session will, for the first time, become an open, free-to-attend session for everyone.


Nigel parry FILP MSLL IEng, orangetekcolour changing luminaires on the highway

Believed to be the first instance in the world, of colour temperature changing luminaires have been installed in Helsinki, Finland.

Helsinki, Finland developed a lighting plan which proposed the idea to have different colour temperatures on the street to suit the time of day and match the human centric circadian rhythms. In the evening they wanted to reduce the amount of blue light and have a ‘warm’ temperature. In the mornings when the locals are going to work, they wanted a larger blue light component to replicate the blue sky in the morning, to help control the Melatonin hormone and make us feel awake. Bear in mind that in Helsinki, it doesn’t get light until nearly 10 am and starts getting dark around 2pm in the depth of winter.  

The first installation is on the approach road on the island, where the oil refineries for Helsinki had been based for many years and they will/may roll it out across the entire island.

The case study paper, will go into more details of the reasoning for this approach, some of the technical difficulties encountered and will have some images of the final installation!


Theo Paradise-hirst fsll, chapmanbdspinspiring atmospheres-designing light for the new design museum

ChapmanBDSP were invited to design the Lighting Scheme for the new Design Museum. This project offered the opportunity to share their enthusiasm for lighting design and to celebrate this sensational Landmark & Icon of design. 

Designing and planning great spaces with integral lighting is both a responsibility and an art, Theo talks about the opportunities and approach developed to help create this world-class venue.

Exemplary Interior lighting for projects should always be a core consideration and can:

  • Enhance an occupants impression of a space.
  • Command attention and assist with the creation of inspiring interiors.
  • Improve visual comfort and extend occupancy / dwell-time.
  • Offer the ability to vary the perception of spatial experiences.
  • Alter and enhance the mood and feeling of an environment.
  • Affect visual perceptions – by varying spaces between generous environments to focused spaces.


‘Landscape character’ is intrinsically linked to a variety of aspects including visibility (views), ecology, heritage and lighting. Assessment of effects (e.g. of development) on landscape character and visual amenity regularly forms a chapter of an Environmental Statement (i.e. an Environmental Impact Assessment) as a ‘Landscape and Visual Impact Assessment’ (LVIA), and are most often assessed for the daytime, with other times of the day often overlooked. Landscape character of a location immediately after dusk, during the night and immediately prior to dawn are recognised as being different to, but as important as, that described during the daytime, and accordingly the process LVIA of is evolving. The process of iterative design, and assessment of environmental effects (including those on humans), is becoming an increasingly multi-disciplinary task, and requires a common understanding and multi-functional solutions. This presentation aims to provide a sound basis to help further the effectiveness of lighting professionals working in partnership with landscape (and other environmental) professionals on their designs and assessment areas in an informed and co-ordinated way.


hayley veenhoven, salix finance and sue kinsella & richard emmett, kent county council – interest-free financing for energy efficient street lighting: kent county council case study

This paper will outline and showcase the success of local authorities across England that have used Salix Finance to enable energy efficiency projects and reduce energy bills and carbon emissions, through installing energy efficient street lights. It will look at the benefits that these projects bring to authorities and include case study examples of projects, as well as details for ongoing funding and how this can be accessed. A focus will be made on Kent County Council’s ongoing LED street lighting conversion, one of the largest programmes of its kind to date in the UK. The programme has been partly funded by Salix Finance. Key representatives from Kent will share technical and delivery lessons learnt from undertaking the programme.


jo ferguson bsc mcieem, bat conservation trust & Harry Fox BSC MCIEEM, clarkson & Woods ltd  – the newly updated ‘bats and lighting’ guidance (2018) for the built environment industry

Understanding the impact of artificial lighting on bats, driven by the dramatic increase in artificial light pollution and huge uptake in LED technology, has led to a great deal of research in recent years. Therefore, the Bat Conservation Trust, Institution of Lighting Professionals and Clarkson and Woods ecological consultants have been busy updating the original 2009 ‘Bats and Lighting’ guidance, which is due to be published in Spring 2018. This talk will focus on the latest research, technology and best practice mitigation.


Christian Macanda, Citel – Surge protection for led street lighting

Outdoor LED lighting system offer huge benefits when comparing to traditional HID lighting, but a major drawback is their extreme sensitivity to electrical disturbances. In this presentation Citel’s Christian Macanda will provide an overview of possible disturbances to LED luminaires, their effects and how to efficiently protect them with the relevant protective measures and the installation of Surge Protection Devices.
