The LED is increasingly a reality in residences, but under what circumstances it is more advantageous to use it in place of dichroic halogen lamps? To answer this question, we compare a halogen spotlights model with an LED model, since both can be used to accent lighting, complementary and in embedded both in residential environments such as stores, restaurants and hotels, among others. To make this comparison, we believe that the two types of lamps can be applied in the same places and with the same purposes. The questions where they differentiate show that can give different effects as a result.
The model chosen for this comparison with halogen dicróica was the Ultra LED MR 16 of the Golden Lamps. When the question is economics, the LED win on big advantage. With powers of 6 and 50W, respectively, the LED system comes to save 88% on the Panel light.
But when it comes to color reproduction, while the Panel light features advantage, since your technology allows the loyalty of the colors of objects.
Another detail is the heat emitted by the lamp. The dicroicas emit 60% of heat back and 40% go to the environment. Already the LED 100% of your heat plays back and the heat generated in the environment is much smaller than the Panel light, have a much lower power and a heat sink.
See the details of the comparison in the table below. If you’re not familiar with the technical terms, we have below a glossary for consultation.
Power: Indicates the power consumption, in watts (W). The energy consumed multiplied by time is equal to the electrical energy used.
Luminous Intensity: Is the amount of light emitted in a particular direction. Its unit of measurement is expressed in candelas (cd). Just ahead, it’s always shown the reference distance in metres (m).
Opening: Indicates the degree (°) light beam aperture, the angle of where the light will illuminate.
Color temperature: Is the apparent color of the light emitted by a source, on a scale of 2000 the 6100 k. at low temperatures the color hue of the light tends to red, which is known as warm light, while in the high temperatures of the light color becomes lighter, being defined as cold light. The your unit of measurement is the kelvin (K).
CRI (Color rendering index): All the colors we see suffer influence of illumination. The reference light with perfect color rendition is sunlight at 12:00, free of atmospheric interference, which assigns the graduation of 100, on a scale from 0 to 100. The floodlights are also classified as 0 to 100 according to your fidelity to reproduce colors. The closer the 100 is, the better the your color rendition.
Average Life: Corresponds to the value at which 50% of the tested lamps remain lit under controlled conditions in the laboratory. This time is not necessarily corresponding to the service life, since voltage fluctuations and other environmental influences can result in the shortening of the average life. In practice, the way you consume a light bulb, your durability can vary up or down based on the value indicated by the manufacturer. Example: the more you turn the lamp on and off throughout the day, the lower your life.
