GGE Puteaux Trail Document - Stage 2
I. Summary
This report by Green Globe Europe Ltd (“GGE”) is on streetlight trials for the Mairie de Puteaux
(west
west of Paris next to the commercial centre
cent called La Defense) – stage 2, phase 1.
1 The 1st report
highlighted the successful results of the 1st trial – 2 induction lights in rue Montaigne, Puteaux.
From the initial successful trail, the city council has asked us to submit a proposal to run a bigger
bigg
trial – 3 whole streets. This is the 1st part of this 2nd stage – the installation of 2 x 150W street
lights (not retrofit kits) in rue Tilleuls. The 2nd part will be done in March, 2011 when the retrofit
kits are installed.
This report provides results of the preliminary measurements.
Conclusions
The measurements show that –
For 50% less power (compared to old passive ballast 250W HPS lights)
GGE/AMKO induction street lights provide as much lux on the ground and
provide better light quality.

Site Information
This section describes the general information about avenue de Tilleuls.
Figure 1 - Google Map of avenue de Tilleuls
In the above map you will see avenue de Tilleuls is a short East/West street split in 2. The left
hand side is about 110m long and has the original 2 x 250W HPS lights. The right hand side is
about 95m long and has GGE induction lights – i) 1 x 150W AF10-B50S-150S 3000K street light;
plus ii) 1 x 150W AF10-B50S-150S 5000K street light. This fitting is shown in the following figure:

150S Street Light Fixture
The old fixtures are shown below.
Figure 3 - Daylight Photo of Existing HPS Street Light,
Light, avenue de Tilleuls
Figure 4 - Old HPS Street Lights Removed & On the Ground
You can see the quality of the lights and also they are old passive ballasts. The street light fixture,
even with brand new globes has poor fixture efficiency.
It is estimated that the fixture efficiencies are • GGE AF10-B50S-150S - > 77%
• Existing HPS
- max. 50%
Note that we also delivered lights with 2-wire
2
0-10VDC
10VDC interface so that
they can be dimmed. This can be done via LONWorks nodes or the ETDE
Citybox.
The next set of photos show night photos of the existing lights.

Figure 5 – Existing street lights, avenue de Tilleuls
One will notice on the 3 photos of the existing 250W HPS lights that they have poor colour
rendition. In the 1st of these you will see 2 cars below the HPS light are blue & red.
As mentioned, 2 different colours of GGE induction lights were installed – 3000K & 5000K. This
was done so that the city of Puteaux can compare light quality against existing HPS lights and also
against the 3000K & 5000K retrofit kits in rue de Montaigne.
Figure 6 - 5000K GGE Induction Light, avenue de Tilleuls
Figure 7 - 3000K GGE Induction Light, avenue de Tilleuls
One will see the excellent colour quality. One can see the green leaves on the tree, the cream
coloured wall and the blue-grey car in the distance.
Measurements of the street were taken so that future simulations can be done if necessary.

III. Measurements
This section describes the measurements taken on the 13th December 2010 between 17h30 &
19h00.
3 lights were measured –
3000K 150W GGE Induction light
5000K 150W GGE induction light
250W HPS
6 readings on the ground per light were taken –
Directly underneath the light
Directly out from the light & halfway on the road
Footpath opposite the light
5 metres from the light along the footpath
10 metres from the light along the footpath
Halfway between
etween the lights along the footpath
This is shown in the following drawings.

Energy Savings Calculations
This section estimates the streetlight savings.
In the 1st stage, ETDE measured the actual power consumption of the existing 250W HPS
streetlights and the induction replacement lights.
ETDE has to take real measurements of the power consumption of the lights.
Even so, we will use the stage 1 readings. They were –
• 250W HPS
- 300W (We are taking a lower estimated in case these lights are better
quality. Avenue Montaigne results were actually 350W)
• 150W induction - 156W (0.7A)
• 48% energy saving
We also know that with passive HPS lights the power factor is very low – approx. 0.8. With
induction lights & electronic ballasts, the power factor is between 0.95 & 0.98.
