Hertfordshire Constabulary’s policing style and organisation is designed to provide a modern, flexible force and an effective policing service for Hertfordshire. Consistent with these objectives is the desire to be environmentally responsible, so during 2010 and 2011 Herts Constabulary installed hundreds of 2ft LED Tubes in place of the old fluorescents.
During 2010, 802 2ft LED Tubes running at 8W were installed in police premises. These replaced 18W fluorescents strip lights. The LED Tubes do not require starters or ballasts (which also consume power) thereby making additional energy savings and removing components which would otherwise require ongoing maintenance.
The savings in electricity consumption achieved are over 60%, giving a corresponding carbon dioxide reduction. Furthermore, the LED Tubes last over three times longer than the fluorescents, saving Herts Constabulary lamp replacement maintenance costs. The longer life of the LED Tubes also means less actual waste disposal of failed tubes, starters and ballasts, which has significant environmental benefits as fluorescents contain the toxic chemicals phosphor, mercury and lead, as well as being made of glass.
