MR16 bulbs and beam angles
Some bulbs have specifications concerning the reflection angle. The bulb reflector determinates the beam angle. For example, MR16 bulb is available with different beam angle: 25, 35 etc.
Higher is the beam angle, wider is the light reflection (less focused). On a contrary, lower is the beam angle, narrower is the light reflection (more focused spot light). Note: ceiling height also has an impact on perception of lighting.
