It's definitely true that plants which consistently get light at night will revert back to the vegetative stage (re-veg). They can also sometimes grow male flowers (herm) from interrupted or irregular night periods. However, I'm not sure anyone knows exactly how much light it takes. It probably depends at least a little on the strain to some extent. The "color" of the light also has an effect, as blue and red light may disturb the night period, but green light does not.
But a safe rule of thumb is your "night" should be less bright than what the plant would naturally get from a full moon. The night under a full moon gives you up to about 1 lux worth of light. Just for reference, 1 lux is equal to the illumination of a surface one meter (3.3 feet) away from a single candle. So you want it to be less bright than that where your plants are!
