Which Light Bulb Is Best For Your Home?

Before LEDs were readily available for home use, if you wanted an alternative to incandescent bulbs, you needed to use CFLs or compact fluorescent lamps. CFLs emit light from a blend of phosphors present inside the bulb. CFLs were engineered as an alternative to traditional incandescent bulbs, which used heat as the power source. CFL light bulbs function on the same technology as those long tubes that were once used to light up our offices and homes. A small amount of mercury vapor and argon is filled inside the tube. Invisible ultraviolet light is generated when an electric current is driven through the tube.

This process stimulates the tube’s phosphor coating to produce a visible bright light. It generally takes more energy than a regular light bulb to light up a CFL initially. However, it needs less energy once it is on. The ballast, which is a small circuit board, regulates the flow of electricity and ensures that the minimum amount of energy is being used to produce the light. CFLs use one-fifth to one-third the electric power of an incandescent bulb to produce the exact amount of light. Moreover, it lasts eight to fifteen times longer. CFLs contain some toxic substances like all fluorescent lamps.

This makes disposing of them slightly complicated. There are many recycling schemes established for CFLs in various countries and are funded by the government.

Now, let’s consider a light-emitting diode, or LED. This lamp discharges light in a narrow band of wavelengths. LEDs are more energy efficient than other fluorescent or incandescent lights. LEDs emit a light that has a similar color to natural daylight. This is measured on a scale known as the Color Rendering Index and its index ranges from 0 to 100 with 100 being the closest to natural daylight.

The most common LEDs produce around 70 to 95 CRI. It is recommended that you don’t use any light that emits fewer than 75 CRI indoors. Unlike most fluorescent lamps but similar to incandescent lamps, LEDs attain full brightness without any warmup.

Which one is Better?

The only benefit I see for CFLs  over LEDs is the price. However, LEDs are becoming cheaper and are more affordable in the long run. An incandescent bulb usually lasts nearly 1000 hours, on average. While a CFL bulb produces the same amount of light to last around 8,000 hours. However, an LED bulb typically lasts around 25,000 hours. Due to this, LEDs might be a little costly at first, but can help reduce your energy bill significantly. Here’s why I think LEDs are a much better choice.

  • They use less energy and last longer than CFLs
  • There are fewer carbon emissions from LEDs
  • Some models are dimmable.
  • They are not affected by quick on/off cycling
  • They usually do not break when dropped accidentally
  • LED’s are not sensitive to humidity

Above all, LED bulbs are non-toxic. In case you break a CFL bulb, there is no need to transform the area into a clean-up site. LEDs also offer a wide variety of  LED surface mount panels that give you plenty of decorating options for your home.  LEDS come in many shapes as sizes as well, including globes, candelabra base, tube lights, and pin lights.

    I have converted all of the bulbs that are left on for long periods to LED. I find them at hardware stores and such on sale as one program or another promotes them. There are several types coming along, dimmable, 3 way, gives off a night light effect when off, etc. I haven’t had a LED ‘burnout’ yet.

    I do have LEDs for some new light fixtures but I will only replace the ‘curly’ CFL’s when they burn out. That may take a while but I refuse to replace perfectly good fluorescent bulbs with the latest craze.
