I'm not the manufacturer of this but I design artistic lighting and I often incorporate incandescent bulbs on my pieces. Nowadays you can only get Edison style bulbs in up to 60 watts, therefore; yes, it'll light up an entire room (small-medium) but it'll be a warm light. LED versions of this bulb would be brighter, but also warm-ish, You could also use a different type of bulb to achieve a brighter light output.
