It uses just 6 watts of power to replace a bulb that uses 11 watts, for instance. That means energy savings of another 45%! More environmentally friendly As well as being more energy efficient, this Noxion LED energy-saving bulb is also better for the environment because it doesn't contain any harmful gasses. Lifespan of 30,000 hours Another benefit the Noxion Lucent LED PL-S EM 2-Pin bulb has over a conventional energy-saving bulb is its much longer lifespan.

LED bulbs may be a little more expensive to buy initially, but the longer lifespan and excellent energy efficiency means a quick return on your investment.
