The Ultimate Guide by VIRIBRIGHT (Charts, Tables, and more)

Over the years, advances in technology have brought about new options in how to light our homes and commercial buildings. In the beginning, all you had was the standard, incandescent light bulb. Now we have compact fluorescent lamps (CFL) and light emitting diodes or LED. We are going to tackle the question… which light bulb type reigns supreme? There are many variables, so let’s dig in!

  • Brightness: which bulb is brighter?
  • Life Span: which bulb lasts longest?
  • Cost: which bulb costs less?
  • LED VS CFL Brightness

    Are LED lights brighter than or equal to Compact Fluorescent (CFL) bulbs? The trick is to understand the technology. Many LED bulbs in the past were not omni-directional which gave the upper hand to CFL in various scenarios. For example, in a floor lamp, the CFL would perform better because the light coverage would be much broader. In most recessed lighting, however, the LED would perform better in the brightness category. Fast forward to new LED generations, and we see the little light-emitting diodes surpassing CFLs in brightness, efficacy, overall energy consumption, and even becoming more competitively priced in the marketplace.

    The chart below shows the amount of brightness in lumens you can expect from different wattage light bulbs. The LED bulbs require much less wattage than the CFL or Incandescent light bulbs, which is why LED bulbs are more energy-efficient and long lasting than the other types of bulb.

    Incandescent Watts  CFL Watts LED Watts  Lumens (Brightness)
    40W 8 – 12W 6 – 7W 400 – 500
    60W 13 – 18W 7 – 10W 650 – 900
    75W 18 – 22W 12 – 13W 1100 – 1750
    100W 23 -30W 16 – 20W 1800+
    150W 30 – 55W 25 – 28W 2700+

    To compare different light bulbs, you need to know about lumens. Lumens, not watts, tell you how bright a light bulb is, no matter the type of bulb. The more lumens, the brighter the light. Labels on the front of light bulb packages now state a bulb’s brightness in lumens, instead of the bulb’s energy usage in watts.power_consumption_450x450

    While lumens is the best measurement of comparative lighting among the various bulbs, it is not always a perfect measure. Some floodlights in can lighting use an internal reflector in the bulb to send the light facing downward.

    Are CFL or LEDs more cost effective?

    Let’s take a look at a 60-watt replacement incandescent bulb. The energy consumption to use a bulb like this would cost about $90 over the course of 10 years. For an LED, running over the course of 10 years the actual cost would be only a mear $18 to operate.

    LED vs CFL vs Incandescent Cost Incandescent CFL LED (Viribright)
    Watts used 60W 14W 7W
    Average cost per bulb $1 $2 $6 or less
    Average lifespan 1,200 hours 8,000 hours 25,000 hours
    Bulbs needed for 25,000 hours 21 3 1
    Total purchase price of bulbs over 20 years $21 $6 $6
    Cost of electricity (25,000 hours at $0.15 per kWh) $169 $52 $30
    Total estimated cost over 20 years $211 $54 $36

    The above chart shows a clear cut winner in terms of price over time with energy consumption factored in. In addition to LED’s cost savings, there are also government backed rebates in some situations for Energy Star products.

    Do CFL or LED bulbs last longer?

    Quick Answer: LED

    Although LED technology for use in bulbs has not been on the market for long, the lifespan estimates for the new technology are astounding and leave CFL and incandescents with little to show for in comparison. With an astounding lifespan of 25,000 hours, LED light bulbs are the undisputed champion in longevity. The next best are CFL bulbs which bring in a respectable 8,000 hours of average life expectancy. Most tests are based on a running time of 3 hours per day.
