How Long Do Compact Fluorescent Bulbs Last
Comparing LED vs CFL vs Incandescent Light Bulbs
3 minute read – The Ultimate Guide past VIRI Vivid (Charts, Tables, and more)
Over the years, advances in applied science have brought about innovations in how to light our homes and commercial buildings. In the commencement, all nosotros had was the standard, incandescent light bulb. Now we have meaty fluorescent lamps (CFL) and light emitting diodes or LED for short. We are going to tackle the question… which light bulb blazon reigns supreme? In that location are many variables, then let's dig in!

- Brightness: which bulb is brighter?
- Life Span: which seedling lasts longest?
- Price: which seedling costs less?
LED VS CFL Effulgence
Are LED lights brighter than or equal to Compact Fluorescent (CFL) bulbs? The trick is to empathize the technology. In short, LED and CFL as technologies do not have a divergence in brightness intrinsically. Brightness is determined by lumens. Lumens is best described equally the measurement of light. A single CFL and LED bulb might have the same lumen (brightness) output but vary profoundly in the amount energy needed to generate that level of effulgence.
Many LED bulbs in the past were not omnidirectional which gave the upper hand to CFL in various scenarios. For example, in a floor lamp, a CFL would perform better because of the calorie-free coverage was, at the fourth dimension, much broader. In most recessed lighting (ceiling), however, the LED would have greater efficacy. Fast frontwards to new LED generations, and we see the petty light-emitting diodes surpassing CFLs in overall free energy consumption, color and fifty-fifty becoming more than competitively priced in the marketplace.
Lumen & Wattage Comparing
The chart below illustrates the amount of brightness in lumens yous tin can expect from different wattages of low-cal bulbs. LED bulbs crave much less wattage than CFL or Incandescent light bulbs, which is why LEDs are more energy-efficient and longer lasting than their competitors.
How to understand this table – wait at the lumens (brightness) in the far left column, then compare how many watts of power each light bulb type requires to produce that level of brightness. The lower the wattage needed, the amend.
| Lumens (Effulgence) | Incandescent Watts | CFL Watts | LED Watts (Viribright) |
| 400 – 500 | 40W | 8 – 12W | half-dozen – 7W |
| 650 – 850 | 60W | 13 – 18W | 7 – 10W |
| 1000 – 1400 | 75W | 18 – 22W | 12 – 13W |
| 1450-1700+ | 100W | 23 – 30W | 14 – 20W |
| 2700+ | 150W | 30 – 55W | 25 – 28W |
To compare different light bulbs, you demand to know most lumens. Lumens, not watts, tell yous 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'southward brightness in lumens, instead of the seedling'south energy usage in watts. When shopping for your next light bulb, simply find the lumen output you're looking for (the bigger the brighter) and choose the bulb with the lowest wattage (the lower the amend).
Are CFL or LEDs more than cost-effective?
To examine the price comparing, let'due south take a look at a standard 60-watt replacement incandescent seedling in this example. The energy consumption to employ a seedling like this would cost virtually $90 over the class of 10 years. For an LED, running over the class of 10 years the bodily cost would be only $18 to operate. Take a await at the table below for a breakdown.
| LED vs CFL vs Incandescent Cost | Incandescent | CFL | LED (Viribright) |
| Watts used | 60W | 14W | 7W |
| Average cost per bulb | $1 | $2 | $iv or less |
| Average lifespan | 1,200 hours | eight,000 hours | 25,000 hours |
| Bulbs needed for 25,000 hours | 21 | 3 | 1 |
| Full buy price of bulbs over twenty years | $21 | $6 | $4 |
| Price of electricity (25,000 hours at $0.15 per kWh) | $169 | $52 | $30 |
| Full estimated toll over 20 years | $211 | $54 | $34 |
Winner: LED (in the long run)
The above chart shows a clear-cut winner when because the price over time with energy consumption factored in. In addition to LED's cost savings, there are as well government-backed rebates in some scenarios for Free energy Star products.
Do CFL or LED bulbs concluding longer?
Quick Answer: LED 
Although LED engineering for employ in bulbs has not been on the market for long, the lifespan estimates for the new applied science are phenomenal and leave CFL and incandescents with footling to show for in comparing. With an astonishing lifespan of 25,000 hours, LED low-cal bulbs are the undisputed, heavyweight champion in longevity. The adjacent best are CFL bulbs which bring in a respectable 8,000 hours of average life expectancy. Go on in mind, most tests are based on a running time of iii hours per solar day.
| Life Span Claiming | Incandescent | CFL | LED (Viribright) |
| Average Life Span | 1,200 Hours | 8,000 Hours | 25,000 Hours |
