You can save most energy by using LED based low energy bulbs, which can save up to 90% of the energy consumed by old fashioned incandescent bulbs for the same light output.
LED based bulbs cost more than CFLs, but last longer and save more energy. So, when considering a more energy efficient lighting system, base your calculations on the long term benefits.And now the LED price has lower much than before.
When choosing low energy replacement bulbs, only select those marked with an “approved” energy label to ensure luminous efficacy. The energy label guarantees that the lamp can operate a long service life and illumination output is able to meet international safety standards.
Use timer control devices to limit unnecessary lighting.
Ageing lamps or dirt on fixtures can reduce total illumination by up to 50%. Periodical cleaning can help aid illumination.
Use the appropriate number of low energy lamps to replace the use of high wattage incandescent types. Do this by referring to conversion tables which compare light output in Lumens. You can use our energy saving calculator for this,just send email us to get it free.
