Did no one but me read the Disclaimer on the bottom of the box. It says 8900 brightness lumens... not 8900 lumens. and on the bottom of the box it says brightness lumens arent the same as photooptic lumens... which is what we are used too.. I wasnt going to bring it up.. and I'm more concerned with agent86's tests rather than what it said on the box.
***just what we need.. not only is lumens mostly worthless but now we have this thing called brightness lumens.
When I say lumens are worthless.. The are worthless for comparing to different types of bulbs (from the plants perspective) but are perfectly valid for comparing like bulbs.. ie the difference between a 400w hps and a 1000w hps. but not a 400w hps and a 400w mh.. surley just knowing the differences in how the bulbs grow you can see that.
last dont argue with me on this.. just accept the fact I hate lumens and I think it's time for a change. For all those that say "lumens are the standard.. just deal with it"... that doesnt mean that there isnt something better(like PAR). Horse and buggy was once a standard too.
