Yup, added them a few days ago. I have some tall Oak trees in my back so I put a few in. He loves them, its so fun to watch. And the crickets use it to, so dinner comes to him now, lol
Make sure you measure your distances... There is a big difference with 2 additional inches with these bulbs. UVI drops off drastically. With a T5HO fixture and a 5.0 bulb your really wanting a measured 8 inches below the fixture for the branch for the approximate 3 uvi.
