The main difference between PAR38 and BR40 bulbs lies in their shape and beam spread. PAR38 bulbs use a parabolic reflector to create a focused, narrow beam, making them ideal for spotlighting or accent lighting. In contrast, BR40 bulbs feature a bulged reflector that produces a wider, softer light, perfect for general illumination and flood lighting in larger spaces like living rooms, offices, or retail environments.
