Luminosity has a mean spectral distribution in the green part of the spectrum. All one has to do is multiply the percentage of red and blue lumens by a factor of 2 times to obtain a close approximation to white-green lumens.
An example: My 250 watts Blue and Red light fixture indicates around 7000 lumens on the meter, so that's equivalent to around 14000 lumens of full spectrum white.
As can be seen in the chart, this only applies specifically to 460nm Blue and or 630nm Red LEDs, which measure at half the true intensity of white-green light.
