Question about lighting cost: Led and T5

Wow, over here in the netherlands we pay around €0,60 per kWh... with that cost the led is much cheaper than the t5 over a 5 year period. so the price you pay per kWh matters too. just running costs for those 2 fixtures over here:
t5 (@100% 12h per day for 5 years): €10 709,10
LED (@100% 12h per day for 5 years): €8 409,60
and this is excluding the bulb changes
Ouch! Our energy costs have gone up over the last 3 years too, but that’s rough! I was previously paying $0.08/kWh. It was basically free at that point.
