In the faq section you are right about the reflectivity of mylar being better than white paint but.......
yes a 1000 watt hps lamp puts out 140,000 lumens but not all of that goes to the sides. most goes down and probably a big percentage is lost to the hood. not to mention the floor and even grow pots can soak in a lot of those lumens like a sponge. in reality I would imagine maybe 30% of the lumens even hitting the sides. then after it reflects back much is lost to distance in the same way it would if you hung your light far from the tops
but yes mylar does help though :-)
