Important Things to Consider When Buying LED Spotlights

led spotlights

Did you know that around 20% of electricity is consumed in lighting across the world? If you have been monitoring your electricity consumption lately and kept your LED Spotlights off most nights, you may have noticed that your electric bills have significantly dropped. But what if we tell you that there’s one simple way to lower your bills without having to keep your lights off at night?

This is where LED spotlights come to the picture. LED lights use 85% less electricity for the same light output as conventional lighting and CFL. If you’re considering replacing all of your halogen spotlight bulbs with energy-saving LED ones, then you’re in the right place. Here, we’ll list the most important things to consider when shopping for LED lights.

Which fitting are you replacing?

Don’t jump into searching for LED bulbs without knowing what fitting of light you are replacing. Is it a traditional screw base? Perhaps you have one of those increasingly popular GU10 (twist and lock) bases.

You can check the details on the box of the lights you currently have and go from there. Here’s an overview of the different types of light bulb bases.

  • E6/E27 Medium (Edison 26-mm or 22-mm diameter)

    This is the most popular of all screw base bulbs and usually used for general lighting in standard light fixtures. From lamps, ceiling lights, outdoor LED spotlights, vanity lights, and flood light fixtures, bulbs with medium screw bases come in many different styles.
  • E12 Candelabra (Edison 12-mm diameter)

    This base type is commonly used for decorative applications. Chandeliers, wall sconces, restaurant pendant lights, Christmas lights, residential or commercial string lights, ornamental lights, and night lights—these light types mimic the look of a candle flame and usually have the candelabra-type base.
  • E14 European (Edison 14-mm diameter)

    Edison 14-mm diameter bases are popular in China and Europe for sign and marquee lights, chandeliers, lamps, wall sconces, and ornamental lights. Common bulbs with this base include A-shaped, small tube-shaped, small globe-shaped, and marquee and sign bulbs.
  • E17 Intermediate (Edison 17-mm diameter)

    The E17 base is commonly used for appliance lights like range hood lights, microwave lights, and refrigerator lights. E17 bases are also used for decorative lights such as Christmas lights, pendant lights, wall sconces, and chandeliers.
  • E39/E40 Mogul (Edison 39-mm or 40-mm diameter)

    E39 and E40 bases are for powerful bulbs with high light output. These bulbs are usually used to replace HID bulbs in industrial fixtures like parking lot lights, canopy lights, and high-bay warehouse lights. Bulbs that use E39 and E40 bases typically have a cylindrical shape.

Domestic or commercial: which type?

You might get confused by the endless options you have. Today, you can find different types of LED lights for domestic and commercial spaces. Many of them are designed specifically for commercial use.

Commercial lights typically come with extra safety features to meet specific needs (though these come at an additional cost). If you are looking for lights to be used at home, check out the LED range for domestic use. Most shops separate them from commercial LED lighting.

What’s the beam angle?

Beam angle really isn’t something that most homeowners have to think about. It used to only concern lighting designers, not until LED lights became a thing among homeowners. When choosing LED spotlights for your home, you have to consider the beam angle.

This is because LED is much more directional in nature than traditional light fixtures. LED bulbs have technology to spread light across a large area, which is measured in beam angles. But don’t get confused about LED lights with a narrow beam angle.

There are different LED bulbs with a narrow beam angle but still give out the spotlight effect like traditional energy-guzzling bulbs with a wide beam. So, consider the area where you will be placing your spotlights.

What about the colour temperature?

Apart from the beam angle, you also have to pick the right colour temperature. Colour temperature is basically the colour the light from the lamp looks, and it helps set the atmosphere of a room.

Colour temperature is measured in Kelvin. Generally, the higher the colour temperature, the “cooler” the light’s colour. For your guidance, refer to the following scale:

  • Less than 2000K  – dim light 
  • 2000K – 3000K  – warm light (yellowish) 
  • 3100K – 4500K – bright white light 
  • 4600K – 6500K – bright blue-white light 
  • 5200K  – daylight 
  • 6500K and up – bright bluish light 

How do you want your room to look like? Would you want warm light with hints of yellow? Now, this is a very personal decision, so you have to think things through.

What is colour rendering?

In addition to the colour temperature, you also have to consider the colour rendering. Expressed as a rating from 0 to 100 on the Colour Rendering Index or CRI, colour rendering refers to how a light source makes the colour of an object appear to human eyes. Just remember that if the light has a higher CRI rating, then it has better colour rendering ability.

Other Things to Consider

Who knew choosing lights can get so technical? To save you from all the jargons, we have gathered other important things to consider when shopping for LED lights.


You also have to take note of the shape of external drivers. LED bulbs today have built-in drivers. As you may already know, LED lights work with direct current (DC).

The driver changes the electrical signal from the mains, AC, to the correct voltage. It regulates the current flowing through the bulb during operation. As pairing LED lights with external drivers can get very technical, don’t be afraid to seek expert advice from the staff in the shop you are buying your LED lights from.


Apart from the issue with external drivers, there’s also the case with dimming. Dimming with LED is actually more complex than traditional lighting. But with the right guidance from the shop’s staff, you can figure out the right dimming functions you need.


This one applies to commercial LED lighting. Commercial LEDs require fittings to be rewired, especially if you’re replacing the bulbs of tube lighting fixtures. As wiring for fluorescent bulbs can damage LED tubes, you may need the help of an electrician to work on the rewiring.

We hope you find these helpful as you go shopping for LED lights.
