Illuminance

Illuminance is the physical quantity used in the measurementof the incident light illumination on the surface and equals tothe luminous flux per unit area. In SI derived units these aremeasured in lux (lx) or lumens per square meter (lm/m2).

Luminous fluxLuminous flux is the measure of the perceived power of thetotal amount of light energy radiated from a light source in acertain direction. The SI unit of luminous flux is the lumen(lm).

LED light

LED light is a lighting fixture using a light-emitting diode(LED), a semiconductor device that emits visible light when
an electric voltage is applied in forward direction.

Calculationof

project Project emissions are calculated by multiplying total electricity

emissionsconsumption of project by the emission factor of captive power
generation using diesel fuels.

Monitoring parameters

Total electricity consumption of project LED lights.

D. Eligibility criteria
This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The project newly installs LED lights or replaces existing lamps with LED
lights as fishing lights for diesel powered fishing boats whose horsepower isover 90 in Vietnam.

Criterion 2

Project LED lighting meets the following specification:- Water proof and dust proof ratings are equal to or higher than theinternational standard IP65.

Criterion 3

In case existing lamps are replaced, a plan for proper treatment (includingre-use and recycling) and disposal of replaced existing lamps is prepared andimplemented according to the relevant legislation in Vietnam to avoid themercury release to the environment.

Sectoral scope: 03
Reference emissions are calculated by multiplying reference total electricity consumption by theemission factor of captive power generation using diesel fuels. Reference total electricity
consumption is computed by multiplying total electricity consumption by LED lighting offishing boat i, by rated electricity consumption of reference lamp and the ratio of the number ofreference lamps to that of project LED lights of fishing boat i, divided by rated electricityconsumption of LED light of fishing boat i.
The luminous flux of reference lamp, which is used for calculating the parameter NREF, isdetermined conservatively in the following manner to ensure the net emission reductions.
- The luminous flux of reference lamp is set at the highest specification among the fishing boat
lamps which are currently available in the Vietnamese market.

F.2. Calculation of reference emissions
Reference emissions are calculated by the following equation:
