Last season I bought a new Hortilux Eye Blue 1000w MH bulb, I think it was a 7500K. From my understanding and based on comments, it seemed to be the best bulb suited for these purposes. This season I bought a new 10000K bulb, which seemed MUCH brighter than the hortilux (in addition to being much "blue-er"). I measured the output from a few different angles and ended up with an avg of 5200 at plant top. I fired up the new bulb (can't remember the name...short term memory loss!) and saw over 7500 in the same locations. So...the Hortilux is considerably less illuminating than the new bulb. With most MH 1000 watt bulbs being between 90K and 110K lumens initially. The hortilux seems considerably less bright despite being used for 1 season during veg only.
Has anyone else noticed a lower output from a hortilux Eye Blue? I have a Plantmax 7500K bulb that I'm going to measure it against to see if it is my imagination. I noticed the Hortilux had a much shorter arc tube than any other bulb that I've used...maybe that has something to do with it.
