What you say sounds reasonable. It would take a year to determine the actual correlations up to a scientific standard, using proper experiments with controls, etc.
But I still feel the LED light I have helps them at night, even if they could get a bead on me without it too.
There could be all sorts of variables: which species of mosquito? Which LED lights? Which weather? Maybe some LEDs are invisible to some mosquitos, and some increase my visibility by 5%. Then, if the weather makes the rosquitos lethargic, 5% is not able to clear a threshold of increased swarming action, but when they are hungry and warmed up, 5% difference in their sense impressions is enough to make the mosquitos go bonkers. The possibility space is too large, which is why I am not a scientist. I don't have the stamina to do 100's of experiments to sort this out to a high standard.
