The brighter 55/60W bulbs are that way because they use a slightly smaller filament so it runs at a higher temperature. There are two downsides to this, firstly the lifetime is reduced... they can compensate to some extent by fine-tuning the gas mixture in the bulb.
The second thing to bear in mind is that the higher the filament temperature, the more UV gets produced. The brightest ones may, if the envelope doesn't include a suitable filter, affect plastic lenses. I don't know about those Ring bulbs, make sure they're "plastic safe" or you might find your lenses turning brown.
