School saves 11 tonnes of CO2 with low energy fluorescent lighting
installation by TGE Group of HILUX luminaires from Tamlite Lighting. High quality lighting is essential in the school sports hall, not only for
M
sport but also for optimal exam conditions. Previous lighting consisted of 400Watt high pressure sodium lamps, with magnetic ballasts, in low bay fittings. The correlated colour temperature and S/P factor of such lighting was extremely poor, giving an orange glow which is only 65% effective for the human eye. Combined with the low frequency ballast, which causes flicker or shimmer, the lighting was not ideal for either sports players or exam candidates. The lights were left switched on even when the hall was not in use, wasting electricity and maintenance of the lamps was expensive. TGE Group reviewed the lighting and prepared a Relux simulation of the hall to determine the best lighting options. Tamlite Hilux luminaires, with T5 high output lamps and high frequency electronic ballasts were recommended to deliver flicker-free ‘cool white’ light to College Badminton standard.
Full and half brightness To ensure maximum electricity savings, TGE Group designed the new
system to offer both full brightness, for sports, and half brightness for non-sporting uses such as exams. An Ex-Or occupancy sensor was also incorporated.
Both the sensors and luminaires are designed to withstand ball strikes,
to prevent ‘accidental’ damage to the system. The new lighting should reduce electricity use by around 64%,
resulting in an 11 tonne reduction in CO2 emissions annually and a cash saving of around £2,300 a year on combined electricity bills and maintenance.
Because all the new lighting meets the ETL criteria for high efficiency lighting units (HELUs), this project also qualifies for 100% First Year Capital Allowance, under the DECC/HMRC sponsored Enhanced Capital Allowance (ECA) scheme. Depending on corporation tax rates, this can speed up project payback by 20 to 28%. Visit
