THE UK’s first indoor cricket space lit with LEDs to international standards has been opened by Gloucester County Cricket Club.
The training facility has been designed to meet the strict lighting requirements set by the England and Wales Cricket Board (ECB).
The ECB’s Technical Standards 2 & 3 (TS2 & TS3) stipulates an illuminance of 1500lux at a uniformity of 0.8.
The LED lighting was specified by gcp Chartered Architects to create the ‘perfect training and practice environment’ for the club while also achieving considerable energy consumption by switching to LED.
Gloucestershire County Cricket Club is one of eighteen first-class county clubs within the domestic cricket structure of England and Wales.
Founded in 1870, GCCC has been at the forefront of English cricket and has played in every top-level domestic cricket competition in England.
The club’s most famous players have been W. G. Grace, whose father founded the club, and Wally Hammond, who scored 113 centuries for them.
The lighting installation comprises Zumtobel’s Craft luminaires which are low glare and highly energy efficient while delivering maximum uniformity.
The units are controlled by Dimlite wireless technology.
The cricket amenity, now renamed as Bristol Cricket Centre, was previously lit using 50 x 400 watt metal halide fittings with a total load of approximately 21 kW.
This was replaced with 35 x 238W Craft LED fittings with a total load of 8.33KW, producing energy savings of over 60 per cent.
Sealed to IP65, the Craft has a specially developed wide beam optic for uniform, square illumination with no dark areas.
It has a colouring rendering index, Ra of over 70, a colour temperature of 6500 K and a transparent PMMA diffuser with additional safety cover.
The lighting installation also meets the ECB’s requirements on glare and uniformity that has been verified by Griffiths Evans, the ECB’s retained lighting consultant.
The Dimlite system and scene plate has also been incorporated into the project to produce three scenes: 1500lux professional, 750lux local and 500lux general.
Additionally, a microwave sensor has been included to act as absence detector and switch off lighting should it inadvertently be left on by occupants..
Dimlite is a multifunction lighting control system that’s modular, with various components connected to a basic module according to requirements.
The basic unit features a series of practical functions such as dimming, a central on/off function and a lighting scene but this can be expanded.
