doesn't work that way, guys | |
the bulb puts out 8,900 lumens. by definition, that's total lumens, measured at the bulb.
so if you could somehow get all these lumens spread over just 1 square foot, you'd have 8.9k lu/ft sq.
reflectors don't add any light; they just direct the light you already have. there's NO WAY a light bulb that puts out 8,900 lumens can measure 19,000 lumens - at ANY distance, with ANY reflector - there just is not that much light to start with. you can't make light from nothing!
agent86, are you sure the meter measured lumens - not micro-candelas or something else??? |
