instantaneous extinguishing, gradual extinguishing Explanation: The former is used in relay parlances, indicating the instantaneous going-off of the light. The latter is a layman's term indicating gradual reduction of light. |

peer agreement (net): +7See explanation below... Explanation: 'drop out' here means that as you progressively dim the lamp down, at a certain point, it suddenly goes out even before it is meant to; imagine that you have dimmed down from 100%, and then suddenly when you reach 15%, the lamp goes out completely. Light levels 'dropping off' suddenly means either the same as the above, or the 'off' can imply (paradoxically!) that the lamp does not go off completely, but simply that the light intensity drops in a abrupt step; imagine that you are dimming down from 100%, and you reach (say) the 20% point on the dimmer scale, at which point the actual light output suddenly drops to 5% -------------------------------------------------- Note added at 19 mins (2005-08-19 11:11:15 GMT) -------------------------------------------------- A synonym for \'to drop out\' here would be simply \'to go out\'; it is important to realize that fluorescent lamps, as they operate by a discharge phenomenon, have a certain \'striking\' or threshold voltage at which they start working; this is what makes them difficult to dim; the \'discharge\' (or \'arc\') inside them has a tendency to die if there is not enough energy (i.e. when dimmed right down) to maintain it. This is why the term \'drop out\' is used, because the arc fails, and \'to drop out\' is a common technical expression for something that fails to keep going. -------------------------------------------------- Note added at 1 hr 5 mins (2005-08-19 11:56:39 GMT) -------------------------------------------------- \'to drop off\' = \'to lessen, diminish\' |
