How to save money and increase your lighting at the same time
How to save money and increase your lighting at the same time
Everyone knows what a light bulb is yet very few really understand them. The common conception is if you want more light you use a light bulb with a higher watt rating. Yes the higher the wattage the more light you get but that is not the only factor. Approximately 90% of the power consumed by an incandescent light bulb is emitted as heat, rather than as visible light.
When shopping for a light bulb what we should be looking at is the lumens rating rather than the wattage.The luminous efficacy of a light bulb is a ratio of the visible light energy emitted to the total power input to the light bulb.
So what does all this mean? Lets say you want a brighter room so you change a standard 60w light bulb for a standard 100w bulb. The lumens change from 870 lumens to 1750 lumens. So in fact you have doubled the light and increased the power usage by 66%. Depending on the manufacturer and materials used to manufacture the light bulb will determine the exact lumens for that particular light bulb.

Lumens Rated Life
GE Basic A19 100w 1710 750 hrs
GE Energy Smart Spiral T3 15w 900 10,000 hrs
If we did things different and installed two GE Energy Smart Spiral T3 what would the results be.
For 10,000 Hours of lighting
Wattage Lumens Total Power Total Bulbs
used required
GE Basic A19 originally 60w 865 600,000w 10 GE Basic A19 100w 1710 1,000,000w 15 GE Energy Smart Spiral T3 x2 15w 1800 300,000w 2
So you can see by changing the way we do things we doubled the lumens from our original 60w bulb and cut the power consummation in half.

There are other options also available that can save you money and increase the lumens without doubling the amount of light bulbs you use. Commercial applications can be the answer.
