With the last of incandescent bulbs being taken off the shelf, the choices for hospital lighting are down to Compact Fluorescent Light bulbs (CFL) and Light Emitting Diodes (LED). Some hospitals have their preferences, while other people have no idea of the difference and just need a light bulb. There are significant differences in the bulbs themselves and the price. Both are good alternatives, but there are pros and cons in the battle of CFL vs LED lights.
Hospitals are notorious for their terrible blue, CFL lighting, which studies have shown can lead to lower levels of testosterone and endorphins and even cancer, according to a study done by Stony Brook University. Here’s why more hospitals should switch to LED lights over CFL.
The average lifespan of a CFL bulb is 8000 hours with is a vast improvement over traditional light bulbs, but it is not a good as the 50,000 hours that the average LED bulb last. The LED lasting 5 times as long on average makes the LED the winner in regard to longevity of the bulb. This lifespan reduces the frequency that bulbs need to be bought and changed.
CFL bulbs contain toxic mercury, which can become a hazard in various hospitals. They should be handled carefully to avoid breakage and disposed of carefully. LED bulbs are more environmentally friendly and do not contain harmful chemicals. So it is imperative to be very careful when dealing with these bulbs so as not to break the glass and release harmful chemicals.
As far as electric usage, LED bulbs use only 6 to 8 watts where CFL use 13 to 15 watts. The CFL bulb cost more to run because they use more watts of energy.
For an individual bulb the CFL wins for price coming in around $3 and the LED bulb coming in at around $8. But as was mentioned earlier the LED bulb should last 5 times as long so in the long run the LED bulb comes out cheaper. The prices of both bulbs are coming down due to increased availability and competition. Technological improvements should bring manufacturing costs down in the coming years as well.
Comfort and Durability
Some people have complained the LED light is too bright and the CFL provides a softer ambiance to the room. Both CFL and LED are beginning to come out with a variety of softness or brightness depending on the where they will be used. LED were originally best used for directional lighting such a flashlights but are becoming more of a viable options for light bulbs as the technology continues to improves.
The LED bulb have an advantage to coming on instantly where the CFL bulb may come on dim then brighten up as it warms up. CFL bulbs are more fragile and easily broken then the LED bulb. CFL bulbs are more susceptible to extreme temperatures than the LED bulbs.
The world is going to CFL and LED bulbs whether we like it or not. The CFL came out first and got a market hold but the LED looks to be making strides in the consumer market by being more efficient and longer lasting. Both are here to stay and both will continue to improve with time. Both bulbs are more energy efficient than the bulb created by Thomas Edison; the LED is superior in terms of lifespan and environmental impact.
