Does a light bulb with greater wattage have greater brightness?

Only within the same technology. / / /
If both of the bulbs you're comparing are incandescent, or both fluorescent, or both CFL, or both LED, then the one that uses more power is brighter. But a CFL with the same brightness as an incandescent bulb uses less power, and an LED bulb with the same brightness as both of those uses less power than either of them.

Yes. If a lamp develops a higher power certainly produce more luminosity, more brightness.

A higher wattage generally means greater brightness for the same type of light bulb, especially for incandescent bulbs. However, different technologies like CFLs and LEDs provide equivalent brightness with lower wattage. For accurate brightness comparisons, it's better to look at lumens rather than wattage alone.
