Paul O'Brien, APSE
Fighting for funding

He will talk about the financial crisis, the state of the market and what the public think of highways and street lighting services.

Helpful for local authorities, contractors and consultants.


Peter Harrison MBA CEng FILP, ILP
Asset Management Toolkit: Minor Structures

GN 22 Asset-management Toolkit: Minor Structures, replaces Technical Report 22 Managing a Vital Asset: Lighting Supports as the go-to guidance for the management of lighting columns, sign posts and the like. This seminal document aligns with the latest guidance for the management of highway assets; Well Managed Highway Infrastructure produced by UK Roads Liaison Group. It promotes and develops a risk-based approach to the management of highway assets including lighting and replaces previous guidance.

Although developed for the management of highway lighting assets, GN22 is applicable to other sectors with responsibility for exterior lighting such as transport, retail and commercial. It develops a new methodology for the assessment of minor structures (lighting columns, sign posts, CCTV poles and the like) leading to a new Column Condition Indicator (CCI) to be determined. CCI can be expressed against a single asset or assets grouped by street, district or town or at a national level.

This talk would be ideal for local authorities, consultants, contractors and asset managers.



He will seek to explain that good asset management can only be achieved by having complete evidence of the condition, service expectancy and effectiveness of any asset. He will also talk about development, the practice of life cycling planning, appropriate intervention and other recommendations made by the well managed Highway Infrastructure code of practice which became effective in 2018.

This talk is beneficial for local authorities, consultants, contractors and asset managers.


Graham Smith, HEA & Peter Burbidge, Ringway / ILP Technical Panel
Considerations, Interactions & Impact of the Construction Design and Management Regulations for ALL Duty Holders

Peter and Graham will explore the CDM regulations through the whole project life cycle.

Peter will cover the duties and responsibilities of the Client, Principal Designer & Designer - Graham will then cover the duties and responsibilities of the Principal Contractor, Contractor & Worker.

More importantly, Peter and Graham will go on to explore the interactions that are required across ALL duty holders to ensure full compliance of the CDM Regulations.

A talk that will interest local authorities, consultants, contractors and designers.


At the ILP Lighting Summit (2018) the big questions on the lips of the exhibiting suppliers was ‘Just how far along is the conversion to LED in local authority lighting?’ From this question, the National Lighting Survey was conceived.

Coinciding with the publication of the official report, the paper will discuss some of the key results from the study. We’ll be reflecting on the progress of conversion to LED within local authorities, alongside a selection of key statistics covering the following topics: lighting specialist employment within local government, retrofitting vs replacing, asset condition and carbon reduction.

Is informative to local authorities, public realm, highways and amenities and contractors.


His presentation will cover the main drivers for the explosive growth in global EV ownership and the fundamentals of the technology of both vehicles and the battery charging systems required to refuel them.

This talk would be great for local authorities, developers, planning managers, environmental, town centre managers and contractors.



The UK government's objective is to decarbonise the new car fleet by 2040 and for almost all cars and vans on UK roads to be zero emission by 2050. The adoption of ultra-low emission vehicles is key to this decarbonisation plan. However, the plug-in vehicle market is still a niche area where technology and customer acceptance are continuing to develop. The market offers both battery electric and plug-in hybrid vehicles, but model choice, availability, price and range are still perceived by many to be inferior to internal combustion engine vehicles. Therefore, to encourage increased uptake, the UK government offers financial incentives towards both vehicles and charging equipment. 

This presentation will summarise the charging requirements of today's plug-in vehicles and outline the funding currently available for vehicles and charging equipment.

Local authorities, developers, planning managers, environmental, town centre managers and contractors would be interested in this talk.



The public realm is seeing the introduction of many new technologies that require electrical supplies, none more than the need to install Electric Vehicle (EV) charging points.

This paper will review the IET Guidance document on the requirements for highway electrical street furniture with specific reference to EV points, their planning, area load capacity assessments, installation and operation but essentially and more importantly the ‘knock on’ effect on other highway electrical equipment. This includes the highway lighting and what changes have to be made to the supplies to such equipment. It is perhaps this later point that has the greatest impact on the lighting community and may see a change in how electrical connections to such systems are made in the future.

This talk is helpful to local authorities, developers, planning managers, environmental, town centre managers and contractors.

Stuart Alexander BA(Hons), Michael Grubb Studio
Wandering Lights: In praise of the narrow wavelength

Stuart is a public realm lighting designer who is on a journey looking at the rise and fall of both sodium and LED street lighting.

Through conversations with a myriad of lighting experts, and visiting a variety of projects, Stuart has been wandering alone…what happens when an LED project is not well thought out? Are we listening to people well enough? How does losing that orange glow affect our communities and places? Too often the subject of new technology is looked at without a backward glance at its predecessor solutions, and online spin results in needlessly polarised arguments.

Applying a creative and personal approach to contemplating this issue, Stuart’s talk should prompt you to reflect on your own experience of sodium, LED, and all light, and take these thoughts with you into your work environment to benefit everyone who uses our streets after dark.

This talk would be ideal for exterior lighting designers, project managers, local authorities, environmental, public realm and street lighting engineers.

Lucy Record BA(Hons), MSc, UCL Graduate
The effects of LED Streetlight Technology on the Nocturnal Urban Residential Environment

As lighting professionals will be only too well aware, the UK’s street-lighting schemes are undergoing a changeover from older sources such as high-pressure sodium (HPS) and high-intensity discharge (HID) to LED technology.

This presentation intends to outline research Lucy has carried out as part of her recent MSc to illustrate how this new street lighting technology affects residents living in suburban environments by exploring factors such as night-time visibility, distribution, preservation of environment, and feelings of safety.

The objective is to clarify the perceptions, needs and priorities of urban residents in order to find whether this, coupled with existing measures to reduce light pollution (for example PIR, dimming curfews and so on) can be ultimately harmonious. Such information forms a valid contribution in determining more precise ways of saving energy and globally reducing light pollution levels.

Exterior lighting designers, project managers, local authorities, environmental and street lighting engineers would find this talk really helpful.


Luke Price MSci MSLL, Public Health England
Can the Adverse Health Effects of Flicker from LEDs and Other Artificial Lighting Be Prevented?

A look at the health effects of flicker, measurements and metrics of temporal light modulation in traditional and modern lighting, and how it relates to some of the recent standards, regulations and proposals.

The talk would benefit exterior lighting designers, engineers, project managers, contractors, consultants and environmental. 



This paper looks at understanding types of glare, disability & discomfort, and the metrics & methods we use to measure and control them in street and tunnel lighting.

It will also look at methods of glare calculation in areas of lighting other than street lighting to see if there are approaches street lighting can benefit from employing.

Lastly, he will discuss if there are glare issues particularly relating to LEDs that we need to consider new methodologies to understand and control.

This talk would be interesting to exterior lighting designers and engineers.

Nigel Parry FILP MSLL IEng, CIE
Maintenance Factors Update – Review of the New ILP Guidance Note and the ISO/CIE recent report

The presentation will highlight the key points in the two new reports on Maintenance Factors from the ILP and ISO/CIE and will update on the CIE recent activity

Maintenance factors are applied to ensure that at the end of scheme’s design life, the worst-case scenario, the specified lighting level is still maintained.  The maintenance factor applied to a luminaire should reflect how its light output reduces over time due to, for example, the effects of lumen depreciation of the light source and the build-up of dirt on a luminaire. 

The methodology of determining the maintenance factor has been extensively documented. However, as the focus of these earlier technical reports was predominantly on incandescent and gas discharge light sources, more clarity is needed to ensure the proper use/translation of the existing methodology towards technologies such as light emitting diodes (LED).

Technologies such as LED distinguish themselves from other technologies by their long lifetime, low failure rate and their integration of components which were previously seen as separate components. As such the previous methods used to determine the depreciation and survival of luminaires might seem unusable and cause uncertainty. However, based on work by IEC the luminous flux depreciation and light source failure parameters have now been re-established for LED-based light sources and allow for translation into an updated way of working to determine the maintenance factor using the existing methodology and data for luminaire and surface dirt depreciation.

This talk is beneficial for manufacturers, public realm, highways and amenities.

David Orchard, Telensa
From streetlights to urban data: how can local authorities collect, protect and utilise their data assets?

Urban data is the mosaic of street-by-street, minute-by-minute information that makes up a city’s digital twin. It includes mapping how people use urban areas, the mix of traffic on the roads, the hyper-local air quality and noise levels. This data is incredibly valuable for designing better urban infrastructure, delivering more efficient services, and making everything more transparent to empower citizens.

The use of urban data has been limited by two barriers. The first is the high cost of single-purpose imaging sensors and the related cost of moving raw imaging data to the cloud. The second is the need for a trust infrastructure to apply best-practice privacy policies to data and provide transparency for citizens on how that data is protected and used.

This session will highlight a new approach to harnessing the power of urban data, using streetlight infrastructure. The Urban Data Project is a group of tech companies, municipalities and thought leaders.  The results of this collaboration are currently being deployed by Smart Cambridge and the initial results will be shared in the presentation.

The audience will get a thorough understanding of the growing importance of streetlight infrastructure in the new data economy. They will also get a clear sense of the pace of this change, and the likely impact and opportunities for lighting professionals.

This talk will benefit local authorities, public realm and infrastructure.


How to overcome the challenge of lighting sensitive natural environments

Lighting to protect the environment is a complex practise with an ever-expanding range of technologies available to lighting designers. There is also increasing legislation and policy to meet as our understanding of the adverse effects of artificial lighting grows.

This presentation will explore some of the challenges faced when designing lighting installations in sensitive environments including how lighting strategies are key to minimising the effects and impacts of artificial lighting on sensitive receptors such as bats, other fauna and residential observers and where the effect of light would be detrimental to the dark sky. The presentation will include a case study for a project that has recently been granted a ‘Good lighting’ award by the Commission for Dark Skies.

This talk is helpful to exterior lighting designers, project managers, local authorities, environmental and street lighting engineers.
