The most common pin connectors are GU10 and GU5.3 (aka MR16) that operate on 230V or 12V, respectively. LED spotlights are very versatile and can be used for general or accent lighting, depending on things like the beam angle, the CRI (colour rendering index) and the colour temperature of the bulb. If you want to be able to dim your LED spotlights, make sure to choose dimmable LED spotlight bulbs. If you like the way your current spotlighting looks, choose LED spotlight bulbs with similar specifications to your existing ones.

If you want to use LED spotlights in the bathroom, it is important that they meet specific requirements because you use the bathroom for different purposes.

The lens first devised by Augustin Fresnel (pronounced fraynel) (1788-1827) is a beehive shape of concentric annular sections that cast parallel beams of light. Comprised of 282 individual prisms, the first order lens can cast a beam of light that can be seen from more than 20 miles. Seguin’s lens was crafted by Augustin Henry-Lapaute of Paris and installed in 1857. The original lamp was lit by kerosene and burned about 2 gallons per hour. In 1907 it was changed to vaporize the oil and the wicks were replaced by a mantle. In the 1950’s electricity came to the island and the lamp was replaced by a thousand watt high powered electric bulb, which is still in use today.

Installing LED spotlights is very easy. When doing so, do pay attention to whether the light source works on 12V or 230V. Do you have an LED spotlight that runs on 12V? Then you need a transformer that converts mains power to 12V. This prevents the LED spotlight from malfunctioning.    But how do you install an LED spotlight? Well, it's quite simple. Do you have a spotlight with two pins at the bottom? Then you push the light source into the fitting and screw it on. Do you have a spotlight with an E14 or an E27 fitting? Then all you have to do is screw it into the fitting.
