Luminous efficiency

The capacity of light flux per watt, which is calculated with theformula below.
Luminous efficiency [lm/W] = Luminous flux [lm] ÷ Rated
power consumption [W]Color rendering index

An index used to quantitatively measure light source’s ability torender the true colors of the object compared to a natural lightsource. The index is measured from 0 to 100, with a perfect 100
indicating that colors under the light source appear the same as
they would under natural sunlight.

Downlight/Spotlight

Downlight is downward lighting directly embedded in ceiling.
Spotlight is downward lighting attached to ceiling-mounted
wiring ducts.

Sectoral scope: 03F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated with power consumption of project lighting, ratio of
luminous efficiency of project/reference lighting and CO2 emission factor for consumedelectricity.
The luminous efficiency of reference lighting is conservatively set ex ante in the following
manner to ensure the net emission reductions.
1. In Indonesia, conventional High Intensity Discharge (HID) lighting, fluorescentlighting and Compact Fluorescent Lamp (CFL) are commonly chosen as lighting
equipment in indoor facilities. However, LED lighting, which is more efficient thanthese conventional lighting, is adopted as reference lighting in this methodology forconservativeness.
2. The average luminous efficiency value of LED downlight/spotlight commerciallyavailable in the global market is defined as ηRE in each rated power consumption

range, as described in Section I.
