We have been used to buy incandescent, halogen and fluorescent bulbs for a long time. When replacing these with LED lamps, sometimes the result obtained is different from what was expected. Some customers report this situation to us. This happens because to purchase these lamps, different factors must be evaluated and not just the power (in watts) as was the case in the past. In this post we talk to you about some of these factors, to make the most of all the advantages of LED technology.
In the past, we had conventional lamps that were divided into incandescent and halogen lamps that provided a warm light, and fluorescent lamps that generated a cold light. Currently, LED lamps come in a variety of color temperatures, which can sometimes cause confusion when making a purchase.
Cool white vs warm white
The color temperature corresponds to the color of the glow that the lamp has. Cool-colored LED bulbs have bluish and white tones, while warm-colored LED bulbs have more yellowish, and even neutral, tones. In the case of a whiter or bluer bulb, it is brighter, has a higher color temperature, and has an energetic and stimulating effect on humans. On the contrary, a more yellowish bulb has a softer glow, a lower temperature, and a more relaxing effect on people.
Depending on the environment you want to illuminate, choose the most suitable temperature.
CRI is the Color Rendering Index. Its value varies from 1 to 100. The value 100 corresponds to the maximum reproduction and is equivalent to a color emission equal to those seen through sunlight. Therefore, the closer the lamp's CRI is to 100, the closer the colors will be to reality.
The value of the lamp opening angle provides important information about the amount of light distribution. If we have two lamps with the same amount of light (lumens) and one of them has a larger opening angle, this means that it will illuminate more area, but with less intensity. We will now show some examples of distribution area depending on the value of the opening angle:
In most cases, halogen lamp dimmers are not compatible with LED lamp dimmers. This is because incandescent and halogen bulbs have a much higher load than LED bulbs. In other words, as these lamps consume less energy, they are unable to reach the minimum load required for the dimmer to work correctly.
If you are going to use a lamp with a dimmer, make sure it is prepared for LED lamps. If it is not, it will also be necessary to replace the regulator for everything to work correctly.
