The document discusses the advantages of LED street lights over traditional lighting options. Some key points covered include: 1) LED lights provide significant energy savings through reduced power consumption and longer lifespan compared to traditional lights. 2) They offer better light quality with uniform light distribution and reduced glare. 3) LED lights are more environmentally friendly as they do not contain mercury or other hazardous materials.

2. The main reasons why the LED lighting is becoming an important role in the industry can be summarized with the following key factors: Big energysavingreplacingexistingsystems Energy saving on newsystems Life of the newtechnology Reductionof the maintenancecosts Better light quality Environmentfriendly Free chooseof the color temperature High electricalsafety and power-onlight immediately Detas SpA - divisione DLEDS www.dleds.com info@dleds.com 2 LED key points

4. The recovery of energy efficiency appears to be a major factor in the consideration of the LED source as an alternative to the existing one.

5. The use of LED technology in the municipal area can be used for street lighting fixtures but also for lighting road bike paths, walkways, gardens, parks, common areas, parking lots, etc..Detas SpA - divisione DLEDS www.dleds.com info@dleds.com 3 Recoveryofenergyefficiency on existingsystems City – Garda Lake Obsolete lightingfixture - Brescia

7. Untilfewtimes ago, the choiceofone light fixtureratherthenanotherwasmadeconsideringaesthetic and performances. Sometimesthischoiceappearsexceeded.

8. If, forexample, sphere light fixtures are replaced ( emitting on 360°) the recoveryof the energyefficientwillbeprobably the max. possible.

9. We can therefore say that the use of LED light fixtures can improve the efficiency between 30 and 70% depending on the individual case.Detas SpA - divisione DLEDS www.dleds.com info@dleds.com 4 How much you can save in percentage terms by replacing the existing lighting with LED technology?

11. Actualavailabilityof led fixtureswith “real” efficiencyof more then 70 Lm/Watt

12. Whatdoesitmean “efficiencyLm/Watt”?

13. Sincethereis no rules on which information havetoappear on the catalogof the LED streetlightmanufacturers or importers, we assist to a different and sometimesmisleading information..Detas SpA - divisione DLEDS www.dleds.com info@dleds.com 5 2. Energy savings on newsystems

14. The efficiencydeclared in the catalog (forexample 100lm/watt or 5500 lm/watt if the lamphas 55 Leds) isrelatedto the LED efficiency at the JCT of 25°C ( asdeclaredby the manufacturer) or to the lamp in workingconditions ?

33. This is usually achieved at least in part by having two layers of insulating material surrounding live parts or by using reinforced insulation.
