Energy savings made by using LED against other types of lamp
LED lamps last much longer - Saving even more
Typically LED lamps have a lifetime of 25,000 hours – that is over 22 years if used for 3 hours per day. Plus, with no filament LED lamps are more robust. This will result in you saving money on replacement lamps and building maintenance. Conventional bulbs last around 1,000-2,000 hours (1-2 years) and CFL around 6,000 -15,000 hours (6 to 13 years).
Save Now - Using 400 Watts in one room? replace with only 52 Watts LED !
Gone are the days when a room was lit with just a single 60W lamp. In living rooms, bedrooms and kitchens - they have been replaced with 8 or more spotlights. Each spotlight could be 35W or 50W (Halogen) - leading to a power usage of up to 400W. With retrofit LED lamps, the energy used is lowered to just 52W (6.5W per lamp), for the same amount of light. With energy prices seemingly only going up - it makes sense to switch to LED.
The biggest savings are seen when LED replaces Halogen or conventional lighting.
If we take a typical example of eight 50W GU10 Halogen spotlights in a kitchen - Retrofit GU10 LED lamps can be installed in a matter of minutes
LEDs save money in two ways:
You will save every year based on less energy usage per lamp
Since LED lamps can last over 20 years, you will save even more by using less lamps
The table below compares a 6.5W LED with a 50W Halogen - with the same light output.
