Incandescent bulbs have to be replaced much more often, and they use five times the electricity of low energy lightbulbs, which means they actually work out to be very expensive.Īs CFLs have become more popular, the costs have come down significantly.
Often people base this assessment on the purchase price only, rather than the whole-life cost of a light bulb. One of the key reasons why more people haven't switched to energy-efficient lighting is because they see them as more expensive. Energy-saving lightbulbs seem so expensive: will they really save me money? Finally, in theory, fewer materials are needed to create the bulbs because fewer are needed, though this is obviously difficult to substantiate. Their longer lifespan means they won’t end up as landfill as readily as bulbs that last for significantly less time, as they can be recycled easily at a normal recycling station. Not only does a CFL or LED bulb use less energy, but a much greater proportion goes into light being emitted rather than heat.Īdditionally, if they use less energy, this dramatically decreases demand from power plants and therefore lessens greenhouse gas emissions. A lot of the energy that incandescent bulbs use ends up being wasted as heat rather than light, but not so much heat that you can benefit from it. Yes, by virtue of the fact that they use less energy than incandescent bulbs. Start to think of lightbulbs as one-off purchases that last many years, like a lamp itself, rather than something you simply throw away after a short time.ĭo energy-efficient lightbulbs really make a difference to the environment? Use side lights with low energy bulbs installed in them if you are stuck with fixed halogen lights that are difficult to replace.
ENERGYSAVER LIGHT BULBS INSTALL
Install low energy bulbs of the correct light output - to match the output you had with traditional lighting, simply divide by five to calculate the low energy equivalent.įluorescent tubes are energy-efficient, and cast the safest light in kitchens.
Turn off lights when you leave a room, unless you are going back within a few minutes.Ĭhoose low energy (compact fluorescent) lighting, there is a bulb available for virtually every situation and to suit all tastes.Īvoid installing halogen lighting, especially the low voltage types which go in recessed fittings in ceilings and walls. Daylight is the most energy-efficient form of light.
