Choosing the right base

There are nine different types of bases a bulb may have. The type determines how a bulb is secured into a fitting like lamps, ceiling pendants and downlighters. Although there are a variety of designs each are just as easy to install and offer the same level of performance.

Bases for bulbs like LED spotlights, bulbs and candles are GU10, MR16, B15, B22, E14, E27, G4, G9 and R63.

To find the type of base fitting you need, check the packaging of the existing bulb that you wish to replace or take a look at the bulb and pair it with one of the options above.

  • GU10 - A GU10 base is found on spotlights. Two studs at the bottom of the light allow it to be locked into place using a twisting action.

  • MR16 - Similar is style and fitting to the GU10 bulb, the MR16 features two pins instead of studs at the base.

  • B15 - As seen on compact golf style bulbs, this small base fitting features two horizontal studs allowing the bulb to be pushed into a fitting and twist-locked into place.

  • B22 - Two horizontal pins on this base allow the bulb to be pushed into a fitting and twisted to secure.

  • E14 - Not dissimilar to the E27, this narrow base has a screw design.

  • E27 - Featuring spiralling grooves, this base is easily screwed into fittings.

  • G4 - The two narrow pins on this base allow the bulb to be pushed in to a fixture to install it.

  • G9 - A set of looped pins on this base is used to push and lock the bulb into your desired fixture.

  • R63 - This short base has an easy to use screw design.

  • MR11 - The MR11 fitting is almost identical to the MR16 fitting, the only difference being that the MR11 is smaller. The last two numbers refer to the diameter in eighths of an inch across the face of the spotlight. An MR16 spotlight is sixteen eighths (2 inch or 51mm), while an MR11 is eleven eighths (1.375 inch or 34.9mm). The MR11 requires 12VDC.

Getting the correct wattage

The wattage of an LED bulb is significantly lower to that offered by the usual compact, flourescent or incandescent lamp. With this in mind, select a wattage from the above list that matches the wattage of the bulb you are replacing. The wattage can usually be found on the base or the face of the bulb.

It's worth noting that with LED bulbs, the wattage amount does not indicate the light output. Light output is measured by lumens, which you can read more about here. The wattage merely indicates the amount of energy used to create light.
