Is light output the same for reflector bulbs?

For reflector bulbs like an R20 or an MR16, Lux is more important than Lumens. Lux is a measurement of light on a surface. Reflector bulbs are available with different beam spreads. A bulb with the same wattage and a narrower beam will have a higher Lux. If you are lighting an object from a distance you may be able to choose a lower wattage reflector bulb with a narrow beam to save money on electricity.
