When Royal Naval Air Station
(RNAS) Yeovilton, through Defence
Estates, embarked on a challenge to
reduce energy use across 10 sites, it
implemented efficient lighting as one
of the measures. For installation with
minimum disruption, Save It Easy
units, developed by lighting specialist
ECSL (Energy Conservation
Solutions – part of the Energys
Group), were selected.

The units transform an
electromagnetically-ballasted
luminaire into a high-frequency
electronically-ballasted one. Instead
of replacing the whole light fitting,
the ballast converter and end cap
converter are fixed on to the ends of
the new, energy-efficient T5 lamp.
