LED MR16 lamps are popular replacements halogens bulbs both in residential and commercial use. The reason for their popularity is that the original, halogen MR16 lights were commonly used in households, and LEDs can instantly replace most of them. Also, LEDs have much better qualities and numerous advantages, compared to their halogen version.

LED MR16 lamps are popular replacements halogens bulbs both in residential and commercial use. The reason for their popularity is that the original, halogen MR16 lights were commonly used in households, and LEDs can instantly replace most of them. Also, LEDs have much better qualities and numerous advantages, compared to their halogen version.

The best way to fully grasp and even appreciate the effective capabilities of the LED substitutions, we have to look at the halogen MR16 lights in short. The halogen MR16 lamp has a reflecting surface: the innermost portion of the lamp is constructed of pressed glass or aluminium in more affordable versions. The glass surface is always under pressure, which makes it so easy to blow up. The reflecting surface manages both the trend and also the disperse of the illumination, escalating the luminosity of the lamp. The bulb is accessible with different beam angles of light right from narrow degrees of 10-to-60, nevertheless, the typically utilized spotlight is about 45 degrees. The colour temperature of the halogen MR16 is really warm, yellowish illumination, and is without difficulty adjusted with dimming.

The main disadvantages of the halogen light is that they have a low conversion rate of power, turning most of it to heat instead of light. Therefore, they have a high power consumption along with very much heat emitted, dangerous not only to touch but also to be placed near textiles or wood during operation. Halogen bulbs are sources of fire hazard in any home, and should be fitted and operated with care. The halogen bulb emits a considerable amount of ultraviolet light dangerous to human health, and is also sensitive to shakes and shock. Both these problems are partially solved with a glass cover that filters most of the ultraviolet light and functions as an explosion shield.

LED MR16 spotlights, nevertheless, do not take a blow from the most of the above-mentioned disadvantages. Though, LED lamps do not have the reflective inner surface, they are called MR spots mainly because they are substitutions of the early reflectors. Beam angle, which is in the same way varied with LED lights too, is usually handled within the optics of the diode. Colour temperature is far more varied in comparison with halogen lights. Cooler white colour temperatures is often closer to natural light, and will not colour the room yellowish. Furthermore, coloured versions of MR16 LED lights are obtainable.

LED lights in general have the advantages of cool running, eco-friendly design, long lifespan (usually around 30 000 - 50 000 hours), and high power LEDs can operate even 24/7. LEDs are not sensitive to shakes or shocks, and operate at low temperature too. The most obvious advantage of LEDs is their extremely low consumption of power. Since LEDs convert 90% of power to light, they emit substantially less heat, and mean no or very little fire hazard in homes. LED lights are also available with GU5.3 for low voltage and GU10 for mains fittings.

For LEDs running at reduced voltage, the operating power source has an important significance. Electronic transformers utilized for halogens are generally unsuitable for running LEDs for two factors. Numerous transformers need a minimum voltage to begin operating, that is not drawn by LEDs using just a small part of the power as compared to halogens. The additional reason is actually more essential from the viewpoint of LEDs, considering the fact that electronic transformers can destroy the LED light bulbs. Halogens tend not to require stabilized current, while LEDs are extra-sensitive to variations in voltage or current. If you are changing your halogen MR16 lights, it is far better to purchase LED suitable transformers as well to guarantee their longevity.
