Lighting –
effective energy efficient solutions
- In the Uk lighting is estimated to consume a massive
58,000 GWh each year.
- That's the equivalent of 580 million 100w
light bulbs burning continuously 24 hours a day, 365 days
a year!
- At say 7p per KWh that calculates at £4,000,600,000.
- This amounts to about 20% of the entire UK generated
output, and contributes some 30,330,000 tonnes
of CO2 into the atmosphere.
- BIG and somewhat disturbing figures.

So, what can be done about it? - other than live
in the dark!
Yes, turning unnecessary lighting off is important, but equally
if not more important is making the lighting we do need operate
as energy efficiently as possible.
Savings of 35% in industrial
and commercial environments are quite typical, with attractive
payback periods typically between one and two years.
In industry and commerce the largest percentage of our lighting
is by fluorescent light fittings, the vast majority of which are
run by low frequency electro-magnetic ballasts. There are a number
of different approaches which can be taken dependent on the lighting
installation profile. These include...
- Optimisation of the lighting circuits at the distribution
board.
- Retrofit existing lamp fittings with high frequency
conversion fittings.
- Replace multiple low frequency electro-magnetic ballasts
with multi-way, high frequency, electronic ballasts.
- Replace the gear tray inside the existing luminaire
casing with a high frequency tray and consider whether
the number of lamps can be reduced.
- Replace the luminaire in its entirety with a high frequency
unit.
- Installation of zonal controls for daylight and/or
movement detection.
- Instigate a policy of re-lamping with long-life tri-phosphor
T5 or T8 lamps.

The first step is to assess the current situation and to then
analyse which options best meet the desired lighting, financial
and environmental issues. We will conduct an initial site survey
at no cost in order to determine which options
merit further consideration and to submit indicative budget costings
and similarly indicative payback periods.
We have seen a sharp increase in the cost of energy, which further
increases the importance of assessing ways to reduce your consumption.
Reduced consumption also means you are addressing your corporate
social responsibility, which is becoming an increasingly important
commercial aspect of the supplier/customer relationship.
