Ballast/gear needed

OUTPUT Read the intermediate steps and the Energy Efficiency Index in the blue cells Steps

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

0.18

5.Energy Class

A+Rated Power (P rated )

8.38External control gear

select "none" if no such gear, "halo" for halogen gear, "LED" for LED gear, "fluo-T5" for T5 or 4-pin single capped fluorescent ballast, "fluo-other" for other fluorescent

ballast,"HID" for HID ballast,"sodi" for low pressure sodium lamp ballast,
