Street light power consumption question

[Rob1984]

Hi guys,

Just an ordinary street light, 400w HPS bulb.

What will be total consumption?

Lamp 400w
Electrical disribution(rectifier) 100w
Comprehensive Cable Loss 6%, 400x6%= 24w
Transformer loss 3%, 400x3%=12w
Reactive Power Compensation, power factor 0.85

Total: (400+100+24+12)/0.85 = 630W

Is this right true?

Please point out where do you disagree, any comments welcome.Also, please write what would be your calculation.

Regards,
Rob
