Are PAR20 and R20 interchangeable?
Either way, the bottom line is that a PAR20 and R20 bulb are the same size and can be used in similar situations, but the PAR20 will be better when more focused light is desired and an R20 will be better for more diffused light and general lighting situations.

BR stands for “bulged reflector.” These bulbs traditionally had a bulged reflector inside the housing to increase the amount of light they put out, giving them a slightly bulging shape. This also creates a softer light to view a wide area without harsh edges or intense shadows.
Can I use PAR16 instead of PAR20?
Both PAR20 and PAR16 bulbs are great replacements for incandescent bulbs, and that is because they use reflectors to accurately direct light. The light produced can easily be directed downward to achieve better spotlighting than other light bulbs….Most Common LED PAR Bulbs.

How May lumens are in a LED bulb?
A 22-watt LED bulb is much brighter than a 60-watt incandescent bulb, because the 22-watt LED produces 1600 lumens, where the 60-watt incandescent produces only 800. Clearly, in the case of measuring LEDs, lumens are the better measurement.
