1.Reference power (P ref )
If Φuse < 1300 lumen : P ref = 0.88√Φuse +0.049Φuse
If Φuse ≥ 1300 lumen : P ref = 0.07341Φuse
46.57watt
2.Power Correction Factor for external control gear (according to Table 2)
1
3.Corrected Power (P cor )
P cor = P rated x Power Correction Factor
8.38watt
4.Energy Efficiency Index (EEI)
EEI = P cor / P ref
