Historic Consumer Research

Existing energy efficient bulbs had limited appeal

Use was limited by

visual impact of ‘unsightly’ stick bulbs

perceived difference in light output

High initial costs for bulb

Consumer confusion at point of purchase


Historic Consumer Research

Many more lighting consumers would use energy efficient lighting solutions if these issues were addressed

Key motivators to usage are

aesthetics

Saves money

Saves hassle (don’t have to keep changing)

Helps environment


Industry has worked on these issues.


Lessons Learnt

Once a member of the public has purchased a CFL and been disappointed in its performance, appearance and life then research shows that it is very difficult to get that person to buy again no matter what the quality.

Maintaining a high quality of product and auditing the quality of the CFL’s being sold is vital to market expansion and support from the public.


Giving the public what they want is also very important.

When we started the E.E.L.S programme we offered to the independent lighting retailers a 15,000 hour very reliable 20W stick or a 6,000 hour look alike CFLi for the same subsidised price of £1 each. Initially for the first month, volumes were the same, after three months we were selling 5 look alike lamps for 1 stick lamp.

A clear indication that aesthetics is more important than life to the domestic end user.

The only time we have been able to really accelerate the sale of the smaller 6,000 hour stick lamps was to offer them for 25p each.


Energy Efficient Lightbulb Scheme (EELS)


Market Figures

Annual sales of filament lamps (excluding halogen) is approximately 297 million lamps.

Of which 178 million are basic ‘A’ shaped GLS lamps which we would like to phase out.

We should accept that there will always be a need for some specialist filament lamps. Imagine a classical crystal chandelier lit with CFL’s, it would look ridiculous.

The other filament lamps, reflectors, candles, tubes, golfballs, etc. will follow on after the GLS phase out as a matter of normal progression and the fast development of LED’s.

It should be noted that 60W candle and golfball lamps will need to be phased out in the final phase otherwise they will be used to replace the 60W GLS.


The EU as a whole

The main problem is the volumes involved.

It is estimated that close to 4 billion filament lamps are delivered each year to the 27 EU countries.

Most of the GLS lamps are produced in Eastern European countries.

There will be enormous costs involved in replacing the production lines as well as the expansion of production in the Far East.

It is not just the expansion of the CFL’ production, it will also mean a huge expansion in the world’s electronics market.

Think mobile telephone numbers then multiply that figure by 20!


The Future

The most efficient way to use fluorescent light sources is to separate the ballast from the lamp.

A separate ballast will give you 25,000 hours life. In the UK we use this principle for our D.E.E.L.S. (Domestic Energy Efficient Luminaire Scheme) programme.By subsidising the cost of the lamp and ballast, the luminaire manufacturer/supplier can supply the luminaire to his retail customer at the same price as the GLS equivalent.

These D.E.E.L.S. luminaires are designed to use fluorescent light sources so the effect is much more aesthetically pleasing than the retro-fit option, it also removes the switch-back problem.

It is important to ensure that these luminaire programmes are expanded on an annual basis in preparation for the LED revolution.


Domestic Energy Efficient Lighting Scheme (DEELS)

+ Free light bulb, which will last for 5 years

+ Save 80% of energy costs


Energy Efficient Lighting Range

The new range includes:Table lamps

Floor lamps

Wall lights

Ceiling fittings

Outdoor lighting

All lines are fully endorsed by the Energy Saving Trust and carry the blue triangle logo

All are designed to take only energy efficient bulbs.

At the Lighting Association Laboratories in conjunction with our members we see the use of retro-fit LED light sources as still being a long way awayWe do believe that the expansion of the LED luminaire market will happen very quickly.There are many problems with LED lighting, not least the understanding of how they work.The biggest problem is heat dissipation. If the luminaire is designed around the LED light sources then the whole of the luminaire will be designed to become the heat sink.When the LED fails just replace the whole luminaire as it will be at least 25 years old and out of fashion anyway.Also renewable energy power sources lend themselves to LED technology which only require 3 to 6 volts of input when running.


The fastest growing light source being used domestically is halogen, either MR16 type dichroic or open capsules.

More research and development responses are being put into improving the energy efficiency of these lamps.We are starting to promote the new RDI MR16 lamps which give an extended life of 5000 and 30% energy saving.We also need to focus more on the phasing out of the linear high wattage halogen lamps especially in domestic use.

We estimate that there are over 17million of these 300W and 500W units being used to light residential property in the UK. Most as security lighting.

These, added to the estimated 8 million torchieres which also use these high wattage lamps, amount to an enormous amount of energy being wasted.


Highly efficient low wattage metal halide lamps are now available together with higher wattage fluorescent alternatives that can give energy savings of almost 90%.


The advances in lighting technology tell us that there will come a day when to run all your lighting will cost almost nothing, with the developments of LEDsrunning on photovoltaic energy.

Lighting has a very important role to play in the worlds need to reduce energy consumption but we do need encouragement and financial support.


Thank You
