The market is flooded with so many light bulbs but which among these to buy is an answer that you should carefully analyze. Based on the purpose, appearance, and energy consumption factor, you can choose among the main variants of light bulbs, which are listed below.
What are the different types of light bulbs that are available?
- LED – Light Emitting Diode (LED) bulbs are now considered the most energy-efficient light bulb that is currently available. LED bulbs save up to 86% of the total energy costs per annum and can last for at least twenty years. It is easy to dispose of, as it does not contain any mercury.
- CFL – Compact Fluorescent Lamp (CFL) is also one of the energy saving light bulb options as it can save up to 75% of the total energy costs annually. However, when compared with LED bulbs, CFL lasts only up to nine years and contains traces of mercury, making it difficult to dispose of
- Incandescent Bulbs – Presently use of incandescent bulbs are being reduced as it does not meet the required energy-efficient standards. Moreover, these bulbs last for the very short duration, maximum one year. Only a few specialty incandescent bulbs may continue to be in production. Though incandescent bulbs do not contain mercury, they produce a higher mercury footprint than CFLs.
- Fluorescent Bulbs – Though fluorescent bulbs use lesser energy than incandescent bulbs, the presence of mercury makes it unfit for use, as it poses a threat during its disposal.
- Halogen Bulbs – These are similar to incandescent bulbs, except they consume lesser energy and do not contain mercury.
- HID Bulbs – High-Intensity Discharge (HID) bulbs are basically used for commercial purposes such as in streetlights, commercial buildings or warehouses. However, they are not considered very good as they are filled with either sodium or mercury vapor in order to conduct electricity.
What should you be looking out for while choosing the best light bulb?
When buying a bulb always check its lumens or watts. Lumens is nothing but the amount of light that is emitted from a light source whereas watts is the amount of energy that a light bulb consumes. Hence, higher the lumens mean brighter the light and lower the watts mean low consumption of electricity.
