How Do GU10 LED Bulbs Compare to Halogen?

by Owner on June 1, 2010

GU10 LED bulbs have been gaining a lot of publicity lately. Still, most individuals don’t really know how they truthfully compare to standard halogen bulbs. Therefore it’s worth taking a few minutes of your time to dive in and take a peek for yourself. Is the GU10 LED bulb everything that it’s cracked up to be and are there any drawbacks or justifiable concerns with their usage?

First, it’s important to clarify what exactly LED GU10 bulbs are. The technology being used is the LED, or light emitting diode. As discussed below, they are both energy efficient and long lasting, and therefore are typically extremely environmentally friendly. The GU10 simply refers to the fitting or connection type, which in this particular case are two cylindrical, knob-like connections that operate on normal voltage.

If you take a look at the benefits of the GU10 LED bulbs, they are very significant. First is the fact that they are extremely energy efficient. They use up less than 10 percent of the energy that a comparable halogen bulb will. For example, a standard 50 watt halogen bulb can be replaced by a 3W to 5W LED, with the common suggestion being a 4.5W bulb. That’s a huge difference and it will make a difference on the bottom line of your bill as well as the overall impact that you’re making.

The other huge benefit to LED GU10 bulbs is that they last much longer than their halogen counterparts. This can be anywhere from 10 to 40 times longer depending on the specifics of what you’re selecting and replacing. Typical GU10 LED bulbs can last anywhere from 30,000 to 80,000 hours.

One of the drawbacks to GU10 LED bulbs is their high upfront cost. They will set you back a decent chunk of change as compared to halogen bulbs when you buy them. However, the upfront cost is quickly offset by both the energy savings and the long lifetime which means far fewer replacements. In fact, switching just one halogen bulb to LED can save you hundreds of dollars over the life of the bulb.

Other concerns about GU10 LED bulbs focus around their light quality and their versatility. While more LEDs are being equipped to work with dimming capabilities than previously, many still do not provide this feature. Also, an LED is generally going to be less bright than equivalent halogen bulbs, and will work better as a focal point style of light as opposed to casting light over a surface. Finally, the color temperatures are higher for comparable LED bulbs than they are for halogen light bulbs.

With all of that said, most consumers and homeowners find that switching to GU10 LED bulbs is an easy choice to make. The extremely low energy usage and consumption coupled with the extremely high bulb lifetime make them the choice for the eco friendly house that can save you a substantial amount of money as well.

Especially as federal regulations crack down on energy efficiency in lighting, its becoming a pressing issue to stay on top of what technology is the most efficient and what the drawbacks are. Its also beneficial to stay ahead of the curve so that as upfront costs like for the LED lights you mentioned go down as they become more common, consumers can jump on the bandwagon as soon as possible!
