"Different light bulbs cost different amounts up front, use varying amounts of electricity, and last for different periods of time. This leads to the commonly asked query as to what the running costs of these different bulbs is how much the different bulbs cost to run.

LED and energy-saving compact fluorescent are two of the most popular types of light bulb. The biggest difference here is how they generate light. LED bulbs rely on an electrical current creating light, whereas energy saving compact fluorescent bulbs generate ultraviolet light and heat that becomes a visible light output once exposed to the phosphor inside the bulb.

When choosing bulbs, it is important to consider more than just the upfront cost. For example, LED light bulbs may cost more up front than a compact fluorescent alternative, but they usually consume less power than compact fluorescent alternatives, and have a longer lifespan.
