MEPS for General Lighting

• Incandescent lamp  (25-200W):  0.24 √ɸ + 0.0103ɸ
• Compact fluorescent lamp with integrated ballast (CFLi)  (up to 60W): 
  • 0.24 √ɸ + 0.0103ɸ
  • CFLi
    • The ratio of luminous flux emitted by the lamps at 2,000 hours to its initial luminous flux is ≥ 0.85; and
    • The fraction of the total number of lamps that continue to operate (light output must be at least 50% of its initial luminous flux) at 6,000 hours is  ≥ 0.5.
    • Covered CFLI
      • The ratio of luminous flux emitted by the lamps at 2,000 hours to its initial luminous flux is ≥ 0.8; and
      • The fraction of the total number of lamps that continue to operate (light output must be at least 50% of its initial luminous flux) at 6,000 hours is   ≥ 0.5.

LED lamp with an Edison screw or a bayonet lamp cap (up to 60W):

• 0.24 √ɸ + 0.0103ɸ
• The ratio of luminous flux emitted by the lamp at 6,000 hours2 to its initial luminous flux is ≥ 0.8; and
• The fraction of the total number of lamps that continue to operate (light output must be at least 70% of its initial luminous flux) at 6,000 hours is ≥ 0.9.

Compact fluorescent lamp without integrated ballast (CFLni)

• The ratio of luminous flux emitted by the lamp at 2,000 hours to its initial luminous flux is ≥ 0.8; and
• The fraction of the total number of lamps that continue to operate (light output must be at least 50% of its initial luminous flux) at 2,000 hours is ≥ 0.9.

T8 Linear, double-capped, fluorescent lamp (LFL) [0.5 - 1.5]m

• The ratio of luminous flux emitted by the lamp at 2,000 hours to its initial luminous flux is ≥ 0.8; and
• The fraction of the total number of lamps that continue to operate (light output must be at least 50% of its initial luminous flux) at 2,000 hours is ≥ 0.9.

LED lamp designed as a direct replacement for CFLni and T8 LFL without requiring any internal modification of the luminaires

• The ratio of luminous flux emitted by the lamp at 6,000 hours2 to its initial luminous flux is ≥ 0.8; and
• The fraction of the total number of lamps that continue to operate (light output must be at least 70% of its initial luminous flux) at 6,000 hours is ≥ 0.9.

Δɸ is the rated luminous flux in lumen.

For covered CFLi, Plamp = Pcovered CFLi x 0.95

2Registered suppliers must declare compliance at 6,000 hours if samples are tested to 1,000 hours only.

A minimum sample size of 20 is required.

If you are selling or supplying the following lamps, please ensure that they meet the applicable safety standards
