High Luminous Efficacy

LEDs can convert significantly more of the energy applied into light rather than heat, hence having the high luminous efficacy. Luminous efficacy is expressed as the ratio of emitted luminous flux in lumen (Lm) and the wattage (W) used. In another word it means how efficient a light source is at converting electricity to produce visible light. The higher the lumen and the lower the wattage, the higher the luminous efficacy.

Low Energy Consumption, Operational Cost Reduction

The major benefit of LED lighting is the massive cost saving as a result of significantly low energy consumption compared to the conventional lighting sources. The saving is not only on the electricity but also on the replacement and maintenance costs.

The operational cost of lighting is about 20% of the overall electricity use in residential and could be up to 80% in commercial. Investing in LED lighting might cost a bit more initially but with their significantly low operational cost can shorten the payback period and not to mention the continuous savings over the long lifetime of the LEDs. For example, the electricity used over the lifetime of a single incandescent bulb is many times the cost of the bulb’s original purchase price (and that is over a very short life). You should also take into account of the enormous replacement and maintenance costs, the time and labour in replacing the lights. These are significant factors for large numbers of installed lights such as in commercial premises. That is like buying 10% ethanol-blended fuel that has inferior fuel economy, which you actually ended up paying more as you use over the long term.

LED lighting works the opposite, a little more upfront and a lot less over the long run, creating an on going waves of saving and positive change.
