- LEDs continue to be the front runner, as they can last up to 25000 hours. In turn CFL models last 12,000 hours . This value is described as an estimate on all lamp housings.Power
- The power of the lamps vary greatly within different models, so the power of the lamp in each case is described, and there is a comparison with other types of lamps. That way, the consumer can identify lamps equivalent to the ones he used to buy.
In the table above  there are examples of this comparison in terms of power and in terms of brightness or luminous flux. Both values are described in the boxes, so it will be easier for the consumer to memorize the brightness value, since it remains similar among all types of lamps.Luminous Flux and Temperature
- The luminous flux must be chosen based on the need for light in space. If concentration and focus are required in such space, such as writing, reading, or cooking, the brightness of the lamp should be greater than in spaces such as a corridor where its use is not as essential.
The temperature, shown in Kelvin, is described in the lamp box and should be chosen considering the activity to be developed in space. In the residential sector the temperature values usually range from 2700 to 5000 K. For a space with a lot of activity like cooking, it should be a higher temperature lamp, which can be called a cold color, with an average value of 4000 K. On the other hand, a space considered to be resting as rooms or rooms should install a lamp with a lower temperature, a hot-colored lamp, which on average has a value of 2700K .
