Thanks for the info Green Dave, I appreciate sharing info.
Those numbers are right, but there's a catch. I'm not trying to argue by any means just sorting it out and trying to gather data collectively. To my knowledge you can't give a plant "too many" lumens. Lumens is just a gauge for the light intensity of these bulbs. I presume that it is the heat that is emitted by the bulb that causes a variety of problems when it is place too close to the canopy.
A 1000w bulb is 140,000 lumens base output, but the newer bulbs claim to go as high as 155,000. However the further the canopy is from the bulb the lumen intensity significantly decreases. Just like with a T5 bulb it is relative to distance. Based on the data I have a 1000w bulb at a distance of 20" puts out about 16,000 lumens. Take a 600w bulb's base output of 92,000 lumens. This bulb at 12" puts out 29,000 lumens. This is about where I run my 600w. Its not even close to the same performance. So my deduction is that the magic number for greater intensity of output on a 1000w bulb is going to be around 12"-13" where there is a significant advantage of lumens to the top of the plant 44k or 38k respectively. Not only that but a greater intensity of light to any of the lower canopy as well for deeper penetration. I'm basing all of my comparisons from what I know about my 600w bulb so keep in mind I have no actual experience with a 1000w system, I only have the performance data comparisons.
