What does “PAR” or “BR” even mean?

Parabolic Aluminized Reflector is referred to as PAR. Bulged Reflector is referred to as BR.

What does the number following PAR or BR indicate?

This figure represents the lamp's diameter in terms of 1/8ths of an inch. A PAR38 bulb, for instance, measures (1/8 x 38)" or 4 34" across. The width of a PAR20 is (1/8 x 20), or 2 12". The width of a PAR16 is (1/8 x 16), or 2". The list goes on and on.

What makes the construction different?

Incandescent, tungsten-halogen, and metal halide PAR bulbs all feature a hard glass cover that is hermetically (airtight or impermeable to air or gas) sealed to the reflecting surface. Some even have LED alternatives, which we'll discuss later. The beam spread is controlled by precisely positioned lenses inside, which are fixed in place in reference to the filament. There is no way to move or change the placement of these objects. Spot bulbs and flood bulbs are both available. While spots concentrate all of the light in one direction, flood lamps dilute or spread the light.

A typical reflector lamp with a bulged reflector is one that uses BR bulbs. They are replacements for incandescent or electric discharge bulbs (as well as LEDs, but that's for later!). The exterior portion of the blown glass bulb has a reflective coating on its sides that directs light. Clear, frosted, or even patterned light transmission patterns are all possible.

Everything sounds wonderful, but how do I use them?

It's a widespread misperception that BR bulbs are better for interior use and that PAR lights should only be used outdoors, such as in corner "emergency light" situations. That is untrue. What matters most is the application and the desired light appearance. In actuality, PAR bulbs' brightness and light temperatures give them superior photometric properties. Additionally, because they are shorter than BR bulbs, they can occupy a higher position in the fixture. This lessens unwelcome glare while making the bulb harder to see (which is desired).

However, this does not mean that BR bulbs are without benefits. The frosted or patterned coating of BR bulbs could give a space the aesthetic you want. Due to the placement of their reflective surface and lens, PAR bulbs also have a tendency to be a little harsher where the light begins and finishes. The amount of light that can spread via the lens is limited by the angle at which the beam is dispersed. As the light approaches the outermost points of the beam spread, BR bulbs typically exhibit a more progressive "fade" in illumination. In comparison to PAR bulbs, BR also cast less shadow.

In the grand scheme of things, there are numerous applications for modern PAR or BR bulbs. In the past, it took some effort to locate an outside bulb that could withstand wetness. Finding such a bulb is rather simple thanks to modern PARs. Even so, PARs are frequently more appropriate for outdoor use than BR or R bulbs. Interior design essentially boils down to how the rooms look. Both are typically thought of for usage as floodlights, recessed lighting, or track lighting. BR or R bulbs are frequently utilised in lobbies and public spaces. Some home theatre applications use PAR can lighting. Nevertheless, you can completely change these based on how you want the lighting in your living rooms to look. Remember that BR lights have "soft edged" lighting and PAR bulbs have a "hard edged" beam spread.
