Tridonic - Cherrywood Warehouse Basingstoke

Light levels are key in many environments to ensuring that workers are not being put at risk, where shadows or low light levels may increase the chance of an accident. Recognising that this lack of uniformity and sub-standard conditions were not acceptable, Tridonic decided to refurbish the entire site.
 

 
Challenge
The existing fittings all contained premium, indoor drivers, and whilst these could be controlled with Basic DIM wireless, they did not provide the additional energy consumption data that the company required to ensure it was optimising its energy consumption.
 
Current standards for warehousing require a minimum of 350 Lux, a significant increase on the installed performance levels in the warehouse prior to the refurbishment. Considering the dual requirements of optimum light levels combined with energy efficient, it was decided to install 30 of Holophane's new Prismpack luminaires, that are specifically designed to provide digital, highbay lighting. These fitting combine superior light control with the latest in highly efficient LEDs. 
 

 
The Solution
Five of the fittings are 1-module models, that each provide 10,000 lumens, two of which incorporate the integral self-test emergency functionality. This self-test capability is also in 15 of the other 25, 2-module, 30,000 lumen Prismpack luminaires. All of the fittings have a 4-pin Zhaga socket which provides an interface with any suitable D4i compatible node, including Tridonic's own control system. One of the benefits of the integral self-test emergency functionality is that it eliminates the need for additional standalone emergency fittings, thereby reducing additional costs. The Prismpack has a class leading emergency output of well over c1,000 lumens, that more than meets standard legislative requirements.
 

 
Once installed the units were commissioned using the basicDIM Wireless system, in a couple of hours. The system is fully automatic and uses ten basicDIM Wireless Sensor 5DP 38rc. These movement detectors operate the aisle groups so that light is provided during the busiest periods and dimmed down at other times.

The Salvation Army processes up to 45,000 tonnes of donated clothing per year, 99 per cent of which is reused or recycled. In keeping with the need for efficiency and improving their green credentials with their trusted partners such as large corporations, supermarkets and local authorities, the Salvation Army sought a lighting scheme that would meet these goals.
