Do BR20 or R20 bulbs identical?
BR bulbs typically have a slower "fade" in light when the light is reaching the limit that the spread of light. BR also create lesser shadows than PAR lamps. Less R20 typically is PAR20 (Parabolic Aluminized Reflector) which emits an even, sharper beam. BR refers to "Bulged Reflector".
Can I utilize BR30 in place of R30?
This reduces how much heat is produced through the bulbs. Therefore, this is that the BR30 bulb is an alternative to the old R30 bulb.
The kind and size of your bulb is determined by the shape codes which is composed of 1-3 letters , followed by the number. A distinct "R" is a reflection and is a mirror-like coating within the glass housing of the bulb that increases the amount of light it emits. BR bulbs are the descendents of the R-shape bulbs and consequently, they are very similar in form. However they differ in that the "Bulged Reflector" bulb (abbreviated by the abbreviation "BR") has an additional reflector inside its neck in order to better reflect light upwards, something that was not previously possible in the sides and neck of the regular R bulb. The extra reflector inside the BR bulb causes the appearance of a "bulge" prior to the point where the socket's base starts.
BR bulbs can be used for anything from floodlights such as they are used for floodlights like the BR40 as well as IR heat lamps such as the BR38. The majority of BR bulbs come with a large necks, with LEDs being the only exception and CFL bulbs, like this BR20.
Once you have determined whether your bulb has an R-shape, or a BR shape, then the numerical portion in the code is the broadest part of the bulb with eighths of an inch. By dividing the numbers of this shape by 8 the result is the size of the bulb measured in inches.

After you've determined the proper size, make sure you have the right voltage rating in order to prevent the bulb from shorting before purchasing a replacement for your fixture. BR and R shape bulbs usually operate between 120-130 voltages.
Where can I use BR Shape and R Shape Bulbs?
In essence, BR and R shape bulbs are directional flood lamps which means that the light spreads over a large area. The light has a more soft edge than PAR lamps (to be explained in the future) and the typical beam angle for each is around 120 degrees in both forms. You're more likely to have a slightly smaller beam angle for smaller R20 as well as BR20 bulbs, whereas R30 or BR30 bulbs are broadly classified as flood or spot lights.
The ER30 Bulb and the ER30 Bulb
With such a wide beam angle BR or R-shaped bulbs work well in areas where wall washing is required or wall grazing, or as track lights for large areas of artwork as well as providing general lighting through lights for recessed cans. If you require a longer-necked bulb to illuminate a deep-recessed can, think about using the lesser-known ER30 and "Elliptical Reflector" bulb to illuminate your fixtures. BR and R-shaped bulbs are available as incandescent, CFL or LED lighting sources. Because of the design of the heat sink and the already directionality of LEDs, the LED BR and R shape bulbs tend to be more an artistic option rather than a necessity for use.
