Yeah... It was a long shot. It's actually from the bloopers at the end when Jackie Chan is trying to say the line about his dad catching a bullet with his bare hands and he can't say the word "caught"
Actually most of those lights (all the yellowish ones at the top) are not led but hps (high pressure sodium) lamps. Against popular belief, these are still the most efficient and effective ones and the main source of photosynthetically active radiation, i.e. pretty much all well-informed weed growers still use the hps lamps. The led lamps in the lower parts of the greenhouse are meant to have the tomatoes carry fruit even where the top lights do not penetrate the layers of green above. Also they do not usually cover those greenhouses. This was a test run with the empty greenhouse, with the plants in it, it will reflect and emit much less into the sky. In the fall/winter time the areas of lit-up greenhouses always look like a close encounter of the third kind.
