LED STRING WHITE 6300K MEDIUM VOLTAGE
• Location : neon sign at roof
• Technical information :- 2 unit @ 360 w => total 720 w- life time hours 50. 000 hrs - lumen 160 lm
• Saving implementation :- Before = 2 unit @ 10.450 w => total 20.900 w- After = 2 unit @ 360 w => total 720 w
- Saving = 20.900 – 720 x 100 % 20.900
= 96 %
Could you explain or provide a
picture of the 2 unit @ 10.450 W ?

In my opinion, you should compare the Savings between
same occupancy.Comparing Jan 2008 vs 2009 provides big savings because of the occupancy difference.Jan2008-Mai2009= 25,000
KwH is more realistic

GREEN GLOBE PROGRAM
FOLLOWING OUR Chief Engineer Meeting and the Presentation of the work we are doing with PHILIPS, each time you want to change lighting, you should ask yourself :
• Am I going to change the Design ? Take a picture Before and After
• What is the lighting ambiance I should keep ? LUX and LUMEN per sqm or else(contact Philips for help to mesure)
• If I use FLC or Halogene or other Lamp producing “Dangerous Gas” : How I will handle the used Bulbs after (Recycle ? Give to a specialized company ?)
• Try to set up a Grid of Return of Investment with the help of the Supplier (philips) is recommended of course)Take into consideration the REAL TIME the light is SWITCHED ON (24 HOURS is only for some specific public areas)
