NIS 1209-1:2024 Minimum Energy Performance Standard - Lighting - Part 1: Lamps

Luminous Efficacy Requirement:

All lamps shall comply with the minimum luminous efficacy requirements for the light source such that:
Minimum efficacy = Base efficacy + Allowance
where “Base efficacy” is set out in two phases in Table 1, and “Allowance” is the sum of eligible allowances in Table 2:

Depending on the characteristics of the lamp, the minimum luminous efficacy values required in Table 1 may be decreased by the following efficacy allowances given in Table 2. For example, a general service lamp that emits 350 lumens could adjust the Phase 1 requirement by subtracting 10 lm/W, such that the minimum required 90 lm/W is adjusted down to 80 lm/W.
