Part A – General Lighting Specification

LED Lighting Requirements 1 As part of the overall Sustainable Lighting Strategy for Abu Dhabi, ADM requires that quality LED

lighting fixtures and solutions are put forward where ever possible. However, where specific tasks may indeed be proved better performed by an energy-efficient lighting technology other than LED then ADM will accept their inclusion as an option in the design proposals and view the technical details before making a final decision.

Where the total lighting installation needs to meet tight project budgetary constraints, then both LED options and traditional energy-efficient technology fixture options must be tabled to ADM with full comparison costings and technical data in order for the final decision to be made. The additional technical specification requirements for LED fixtures necessary to ensure quality solutions are proposed is detailed within this specification alongside the basic lighting specification and design requirements.

Solar Lighting Requirements

2 ADM strives to be a leader in sustainability and as part of this aim it is required that for every park and public realm lighting project the Consultant is to explore the current viability and options for solar lighting solutions in the marketplace and propose where best it can be offered for incorporation into the project.

Particular attention should be paid to areas of the project which might provide specific advantages for having some solar lighting technology and/or their cost of implementation can be mitigated by other factors. These include, but are not limited to, interactive/awareness zones, integrated with local structures, isolated areas without current electrical infrastructure, dedicated sports areas, children’s play areas, sculptures/arts or specific paths.

ADM may require detailed cost/payback analysis to develop any approved options through to Detailed Design and Tender Issue.

General Lighting Requirements 3 The design, specification, calculation, manufacturing, testing, shipment, installation and

performance of lighting system shall be in accordance with the applicable requirements of all ADM general electrical standards for electrical distribution works, except as specified herein. Copies should be requested from ADM if not already held. The luminaires shall be designed to operate continuously at the specified ambient temperature and humidity with special attention given to the occasional sand storms and dusty weather in specifying/designing the luminaire body.. The manufacturers shall guarantee adherence to this Specification and the performance of their luminaires under all the required design conditions.








4 The luminaires shall be provided with suitable optical assemblies for their locations and tasks as

indicated on the drawings and shall provide efficient even glare-free illumination with correct cut-off angles as set out in CIE 126-1997 (Guidelines for Minimizing Sky Glow. Commission Internationale de L 'Eclairage / 01-Jan-1997) and the overall requirements for Estidama Communities projects as applicable for the area and zone of the project.

The luminaire housings shall be of either extruded aluminium or die cast aluminium with very low copper-content and high corrosive resistance. The finish coating for housing shall be with an anti-corrosive anodized/painting process or equivalent, providing excellent UV and environmental exposure resistance to fading, peeling cracking or corrosion. The control gear/driver(s) shall be integral or remote as applicable, encapsulated/potted or non-potted as applicable for the fixture and protected in a waterproof(IP) environment, enabling access to the gear for easy maintenance requirements. The fixtures shall be CE or UL certified, or comply with equivalent international standards with all certification made available if requested.

a/ As per LM-79-08 or approved International equivalent. Simplified B20-L70 threshold. A minimum of 50,000 operating hours before reaching the B20-L70 lumen output degradation point with no catastrophic failures. The B20-L70 lumen output must be capable of providing the luminance level and uniformity.

b/ Site performance method. A life time of number of hours specified by the site based on expected site lighting useful life must be capable of providing the luminance levels of uniformity.








35 LED Useful life testing and verification procedure

Simplified B20-L70 threshold. Perform LM-79-08 (or approved International equivalent) testing on the luminaire at both time intervals of 0 hours and 6,000 hours. The luminaire shall be operated continuously in the appropriate UL 1598/153 environment or equivalent except when it is removed to perform the LM-79 light output tests. If the light output determined at 6,000 hours is ≥ 96%, the light output determined at 0 hours, the luminaire meets the simplified B20-L70 threshold for useful life.

36 LED Site Performance method

a/ Perform lumen depreciation testing per LM-80-08 (or approved International equivalent) on the light sources (s) (module/array) for a minimum of 6000 hours (longer testing period is encouraged). Identify the installed (in luminaire) operating temperature of the LED using the Ts point under operating ambient temperature of 50-degreesC. From this interpolated curve, determine the lamp lumen depreciation (LLD) value and useful life that meets the needs of the site defined hours of operation to end of useful life as well as the luminance level and uniformity required.

Project Performance Requirement - The following factors shall be applied to

determine the performance requirements for all luminaire types:

37 Light Loss Factors (LLF)

LLF = LLD x LDD (Lamp Lumen Depreciation x Luminaire Dirt Depreciation)

a/ Assume Lamp Lumen Depreciation (LLD) 0.70 for dedicated luminaires except where recommended otherwise by the luminaire manufacturer. Assume the appropriate effects from life/temperature on the lumen output of the luminaire. Note: For LED fixtures the figure used should only match the stated Lumen Depreciation value given by the manufacturer for 50,000-hour operation at 50-degree ambient.

b/ Assume Luminaire Dirt Depreciation (LDD) using appropriate and stated depreciation factors to suit actual environment and resistance properties of the specific fixture.

Photobiological Safety The Manufacturer/Supplier shall provide a written undertaking to

the satisfaction of ADM of testing to the following standards:

38 Ensure luminaire complies with Photobiological Safety of lamps and lamp systems in accordance

with the requirements of BS EN 62471:2008 or A N S I / I E S N A R P - 2 7 . 3 - 0 . Provide proof of testing and compliance with the standards with certification provided to prove the fixture is classed as “Exempt”.

and the district brightness; it is assumed that the building surface is reasonably matt; specular finishes will require additional special consideration.

Successful building floodlighting depends on much more than achieving the recommended maximum average illuminance and there is only an indirect relationship between illuminance, luminance and the visual effect produced.

The simplified procedure comprises of 5 steps:

• Determination of required illuminance;

• Choice of lamps and floodlights best suited to the project;

• Calculation of the number and wattage of floodlights and/or architectural feature lights needed to give the required illuminance;

• Determination of best mounting positions for floodlights;

• Specification of aiming directions for the floodlights.

*Based on reflectance for a white light. Values will need to be adapted for light sources with a

defined colour, illuminance should then be defined in accordance with clause 40 and be decided with site trials/mock-ups.

**Typical districts are: Low Brightness – Rural, Medium Brightness – Suburban, High Brightness –

Town and City Centres. Refer also to the requirements of Estidama.

41 Coloured Light Conversion Factors when using Filters

It is important to remember that the colour of surface material is accentuated if light of the same colour is used. Also attractive effects are sometimes achieved by using light of different colours at different times and/or in specific locations. The following table gives the factors by which the calculated illuminance based upon white light, has to be increased in order to achieve the same apparent value visually with coloured filters are proposed These factors take into account the fact that coloured light is more conspicuous but also the transmission losses of different filter colours. Where ever colour is proposed these are only general guidelines and it is always suggested to physically test and mock-up the proposal before finalizing the design and fixture specifications.

.

42 Coloured Light when using coloured and RGB LEDs

Coloured LEDs, emit coloured light directly from the chip without additional filtering required. As such the values obtained within lighting design software from luminaire photometry can accurately compared against white light fixtures and the resultant illuminance and luminance figures a good guide to effectiveness. Conversion factors do not need to be applied as the outputs in all colours is achieved at 100% of the rated outputs. However it is always suggested to physically test and mock-up any coloured lighting solutions within the proposal before finalizing the design and fixture specifications.

Project Lighting Calculations - The following performance reports of the lighting

installation shall be submitted for approval along with the material submittal:

43 Computer Generated Photometric Analysis of Proposed DAY 1 (Defined as the initial illuminance values):
