The Efficacy Milestone
For context, a standard incandescent lamp produces around 15 lm/W. The leap to 200 lm/W represents a 13x improvement in raw efficiency. In practical terms, a 10W luminaire can now produce as much light as a 130W incandescent — dramatically reducing energy costs and cooling loads in large commercial installations.
Impact on Green Building Ratings
Indonesia's Green Building Council (GBCI) rating system awards points for lighting power density (LPD) below defined thresholds. At 160+ lm/W commercial efficacy, projects can achieve LPD levels below 5 W/m² in offices — easily surpassing Greenship requirements and qualifying for maximum lighting energy credits.
