# How Many Lumens is a 60-Watt Bulb?

While Watts determines the electrical power of the bulb, the lumens determine how actually bright the bulb is.

60-Watt incandescent bulbs are very popular light bulbs, or at least they were - they are being replaced with more energy-efficient light sources, mostly highly efficient LED light bulbs. But, how many lumens have an ordinary 60-Watt incandescent bulb,s and what is the wattage of the equivalent LED bulb...

## Luminous Flux (Lumens) vs. Wattage

The following comparison chart lists typical luminous flux (lumens) for various light sources and their electric power consumption (given in Watts):

 Lumens Incandescent(Tungsten) HalogenIncandescent Fluorescent LED 90 15 6 2-3 1-2 200 25 3-5 3-4 450 40 29 9-11 5-8 800 60 13-15 8-12 1100 75 53 18-20 10-16 1600 100 72 24-28 14-17 2400 150 30-52 24-30 3100 200 49-75 30-36 4000 300 75-100 40-45

As one can see, an average 60-Watt incandescent light bulb provides about 800 lumens of light.

On the other hand, an equivalent LED bulb consumes 8-12 Watts with a typical power consumption of ~10 Watts - that means that the LED light is, on average, 6x more energy efficient than incandescent lights, leading to significant energy savings.

And energy savings means money savings, right?

## Energy and Money Savings

For example, if the 60-Watt incandescent bulb operates 8 hours per day, 30 days per month, then:

E = 60W * 8h * 30 days = 14400 Wh / month = 14.4 kWh / month

With the average price of 0.15 \$US per kWh of energy, that means that a 60W bulb running 8 hours per day, every day during the month, spends energy worth 2.16 \$US.

Obviously, this is not much, but to light up a single mid-size room, one needs several of these light bulbs.

If such 60 Watt incandescent light bulb is replaced by 10W 800 lumens LED light bulb, then:

E = 10W * 8h * 30 days = 2400 Wh / month = 2.4 kWh / month

and with an average price of 0.15 \$US per kWh of electric energy, the cost of running such LED light is 0.36 \$US.

So, if we replace a 60W 800 lumens incandescent light bulb with a 10W 800 lumens LED light bulb, we may save ~1.8 \$US per month.

Since single 60W 800 lumens LED light bulb costs slightly more than a dollar, such an LED light bulb pays for itself after less than a month.

Note: when looking for LED lights, be sure to get the color/temperature that best suit your needs. For example, 2700K LED lights may appear too yellow, while 4500K LED lights may appear too white/bright. LED lights with a temperature of around 3000-3500K are the best choice for indoor use for most people; but again, we are all individuals...

However, if You are still using incandescent bulbs at home, consider switching to LED lights - they are very energy efficient, and even with moderate use, they pay for themselves in under the month...
