The benefits of LED solutions

LED lighting is clearlythe most efficient lightsource for outdoorlighting. Secondly italso gives a lot ofadvantages comparedto conventional lightsources.

Big energy savings up to85%

Good color rendering, makingit easier for users to orientatethemselves

Long life - up to 100,000 hrsresulting in less maintenance

Uniform high quality white light

Good opportunities to dimlight when it is not needed

Easy to upgrade - the flight source

ReliabilityBe skeptical of all claims

Ask for genuine test reports, data andcertifications. Ensure claims refer tosystem performance and not just one ofthe parts.

Examine disclaimers closely thesecould hide vendors inability to producequality products consistently.

Ask for companys industry and financialhistory only work with reputable,financially sound companies.

ExperienceEnsure partner can fulfill warrantypromises

Choose company with a long trackrecord in projects

Ensure the company will still be aroundwhen warranty is needed check financialstability.

Check the fine print, ask for systemwarranty - total coverage on all the parts.For example, warranty on just thehousing is not good enough.

The building blocks of LED solutions

LED solutions are built up by 3 groups of componentsOptical componentsPerceived to deliver the same or better light effect as the original light source (beam shape,intensity, colour point, colour rendering), and equal or better light quality variation betweenlamps

Electrical componentsNeed to be 100% compatible with the electrical input power characteristics and 100% compatiblewith installed accessories (dimmers, transformers), while causing no non-compliances

Mechanical and thermal componentsMechanical compatibility (shape, size) into an existing installation and thermal compatibility intoexisting applications

The new lighting facility immediately extends waking andworking hours in the evening. Social interactions mayincrease, as may the sense of security due to lighting. Longerdaylight hours may alter the time use pattern of both men andwomen.

Solar powered lighting facility enables people to have moreoutdoor activities, e.g. sports, after nightfall.

With a higher-capacity Solar Indoor Lighting Unit, the surpluselectricity for running a TV may provide scope forentertainment as well as information which may be of value.
