All Grow Lights lose a lot of light value with distance. The problem
with the kind of lights you have is that they produce so much heat, you have to
keep the plants too far away for the lights to do much good.
If you know a commercial/portrait photographer you might borrow his
light meter, measure your shade and then measure your grow lights.
If you live in a large enough metropolitan area a local camera store
might rent you one.
