Par16 vs MR16 Light Bulbs: What is the Difference?

Whether you are updating your light fittings or just looking for replacement bulbs, there are plenty of light bulbs to choose from. Aside from making sure the bulbs fit, you want to choose the most cost-effective option. LED light bulbs tick the box but there is still a wide variety.

We are going to look at the Par16 and the M16 LED light bulbs. Despite the same number, representing the diameter, the two bulbs are very different. This is represented by the letters. The chart below shows the average specifications, but different brands will have alternatives.

The difference between the letters is that a PAR bulb is a parabolic aluminized reflector. These bulbs generally have a beam angle of over 45º. The MR stands for multifaceted, and the beam angle is narrower, between 15º and 45º. If you are looking for more focused light, the MR16 is the better option.

Another significant difference is the base. The Par16 is most commonly found with an E26 screw-in base. The MR16 has a GU 2-pin base. This base is typically a GU5.3 or a GU10. The number represents the distance in millimeters between the pins. Even though they are the same size, they aren’t interchangeable unless you have an adapter.

In terms of light, the Par16 tends to be around 4W (a 35W incandescent equivalent) and provides between 300 and 400 lumens. The MR15 is slightly brighter at 5W (40W incandescent) and between 560 and 710lm.

There are different options in terms of Kelvin. A lower Kelvin, for example, 2700K, gives a warm color. A Kelvin of 5000 is a cooler light, similar to daylight. The Par16 and MR16 are both available in dimmable and non-dimmable.
