I know nothing of correct technical terminology โ only what can be found from respected bulb manufacturers. What makes an LED more desirable than a CFL? Dimmable? Lower wattage? Color/Kelvin? Longevity? Appearance? Many terms are used when referring to todayโs lights. The term cool can also mean daylight and be in the 5000K range which is also at the beginning of the blue spectrum so some say blue โ as opposed to the yellow of the 3000K warm range bulbs. Some form of these terms will be found on the packaging. The normal civilian citizen does not need to know more and does not need any degree in engineering to purchase a light bulb. CFLs are now deemed hazardous and hazardous to dispose of due to mercury and other contents.
In our RV we use many configurations of various sizes and types of bulbs to provide our lighting from many base types. But that might get a bit more complicated for the everyday consumer.
Here is but one example of what you might find at a place such as Home Depot. A pack of 8 bulbs for just under $70. These are the top rated bulbs which draw very little current and therefore can lower the users light bill. They can last 20 years or more depending on hours per day of use.
