There is no standard red LED, look at a catalogue of an electronic components supplier for red LEDs, there may be hundreds listed, with a very wide range of luminous intensities, determined by the manufacturing method.
You have to rely on reading the data sheet for any particular LED, and look at the spread in this parameter. Often this will be shown as a single line on a graph versus current (to which the intensity is related) , and there may be a significant statistical spread. Manufacturers may sort the LED from a batch according to wavelength and/or luminosity, which gives the user lower spread in the specifications on a particular LED.
