LED bulbs last up to 10 times as long as compact fluorescents, and far longer than typical incandescent.
Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, LED bulbs hold up well to jarring and bumping.
These bulbs do not cause heat build-up; LEDs produce 3.4 btu's/hour, compared to 85 for incandescent bulbs. Common incandescent bulbs get hot and contribute to heat build-up in a room. LEDs prevent this heat build-up, thereby helping to reduce air conditioning costs in the home.

No mercury is used in the manufacturing of LEDs.
LED light bulbs use only 2-17 watts of electricity (1/3rd to 1/30th of Incandescent or CFL). LED bulbs used in fixtures inside the home save electricity, remain cool and save money on replacement costs since LED bulbs last so long.
Although LEDs are initially expensive, the cost is recouped over time. LED bulb use was first adopted commercially, where maintenance and replacement costs are expensive. But the costs of new LED bulbs have gone down considerably in the last few years, and are continuing to go down. Today, there are many new LED light bulbs for use in the home, and the cost is becoming less of an issue.
Your average 12v 50w halogen turns 90% of the electricity it uses into heat and only 10% into light. This means that halogen downlights are extremely inefficient. Halogens also use transformers which themselves use between 10w & 15w, so your standard halogen is using about 60 watts. Many people believe that Halogen lights are very energy efficient because they are often referred to as low voltage lighting. Although they are low voltage (12V) this doesn't mean they consume less electricity. The coil inside the globe gets so hot that it glows, and that is what creates the light. You can think of Halogens as little toasters in your roof, burning up energy. Halogens can be a fire hazard because they get so hot.
We have a range of LED downlights to replace energy hungry halogens. LED downlights last between 20 and 50 times longer than traditional halogens (LED's lasting for 50,000 hours would last for an amazing 20 years, if used for 6hrs/day). LED downlights use only around 10% of the power of halogens and provide up to 90% of the light output.
