How bright is 600 lumens? What equivalent wattage of bulb does that equate to?

I'm not sure I've ever seen (or noticed) a lumens rating on any lightbulb I've ever bought, therefore have no frame of reference. Normally, energy saving bulbs tell you the equivalent wattage tungsten bulb they would be as bright as (e.g. 40W, 60W, 100W, etc.). So... how bright is 600 lumens compared to the bulbs I've been buying for the last 40 years?
