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.
When shopping for floodlights, you will see both BR and PAR options available. These lights are very similar and have the same color options, but they do have some distinct differences. Both can be used indoors and out, depending on the bulb and the light fixture, and both have LED lighting options. So, which one is right for you? Understanding the differences between the two will help you make an informed choice for your lighting needs. 2b1af7f3a8
