- Cost. Each time you need to buy a new bulb it costs money. An incandescent bulb will need replacing 15-20 times more often than an LED bulb. Even a long lasting CFL will need replacing twice as often. This means when comparing the raw cost of bulbs, you need to calculate the cost per year of each option. When you do this, LEDs are the clear winner.
- Time. Each time a bulb needs replacing you need to factor the time buying and changing the bulbs. This may not feel a lot, but in a larger business with many lights this can add up.
- Embodied energy. This is really the most important factor. Each bulb needs raw materials, manufacturing, storage, and transportation to reach you. Every step requires energy. The fewer bulbs you need, the less embodied energy is wasted (making them better for the environment).
