Light-emitting diode lights are attractive options for lighting primarily because they save energy. A 7.5-watt LED bulb produces as much light as a 60-watt incandescent bulb, an almost 80 per cent savings on electricity costs. LED bulbs can also emit quite bright light that is closer to the clean, clear light of the sun than most household bulbs. That said, there are some drawbacks to take into consideration.
LED bulbs are much more expensive than incandescent lamps. An 8-watt bulb can cost about £26, versus around 60p for an incandescent bulb that produces equal light. While the LED bulb can eventually offset the initial outlay, as it lasts up to 30 times longer than an incandescent and uses about one-eighth of the electricity, if upfront costs are an issue, an LED bulb may not be for you.
In contrast to other types of bulbs, the light from an LED bulb is largely directional. This means that the light is more focused, and thus it is harder to light up a large area like a living room or playroom. While LEDs are great for task lighting like cutting vegetables or reading, for instance, they are not ideal where you want broad, full illumination in the home.
Heat dissipation can be a problem for LED bulbs. If the heat of the bulb is not dispersed, the bulb can burn out prematurely, which can be an expensive failure. Higher-lumen bulbs in particular are prone to this problem, and some feature space-age fins to combat this.
LED bulbs frequently do not work with dimmers. The colour of many LED bulbs is a cool white that is harsher than incandescent bulbs, though bulbs with light of different colours are available.
