LED Lighting For Commercial Premises
It's a fact that not all incandescent, halogen and CFL lamps will fail at the same time so the maintenance cost has been applied individually, it would also be fair to say that some bulbs could be replaced by staff but not all.
Considering the comparison, it is evident that LED lights are without doubt the most affordable by a significant margin for use in commercial operations due to their low energy consumption, long lifespan and incredibly low maintenance cost.
