What Is A GU10 Light Bulb?

In simplest terms, a GU10 light bulb is a unit which is designed to fit into downward lighting fixtures (such as high hats) and spotlights. However, it should be noted that the GU10 series is actually quite different than a normal bulb. So, what are the main hallmarks of this design and which features have allowed such a model to be so very popular for a variety of downward lighting needs? Let us take a closer look at the answers to both of these questions.

A Specific Lighting Design

We should first observe that this model is actually what is known as an "MR" bulb. This is an acronym for "multifaceted reflector". Tiny flat surfaces within the glass enable the light to be dispersed in broad directions. This allows such bulbs to be quite efficient at lighting large areas; hence their use as overhead fixtures. Also, the majority of designs boast a similar size. This enables one to be changed out quickly and easily. The types of light sources include variants such as the GU10 halogen and the GU10 LED. Now that we understand the basic principles, what separates the halogen variety from its LED counterpart?

Halogen Versus LED

The GU10 halogen bulb has been in existence for a number of years. While it provides ample light, it also becomes quite hot to the touch. Not only does this make changing the unit difficult, but greater heat equates to a shorter lifespan. This complication has been addressed with newer GU10 LED models. An acronym for "Light-Emitting Diode", LED bulbs generate little heat. They can be found in a number of colours and are quite energy efficient. Perhaps most importantly, GU10 LED bulbs will last for thousands of hours longer than a traditional halogen variant. These are some of the reasons why LED models are becoming so very popular within homes and businesses.

Of course, the ultimate choice will revolve around the unique lighting needs of the customer, one's budget and the environment that needs to be illuminated. The GU10 bulb is one of the most common and universally recognised lights in these modern times.
