high lumen induction grow lights

I saw a you tube video on induction grow lights then I did some research and got to see a couple in my grow shop. These really are an astonishing fixture that we've been getting excellent kush yields at 300 g/p/meter on average. The cfl and led don't get enough light on the lower branches and the lumen output on led is not even advertised. so to get the high par values for both veg and flower and in the interest of saving money on lamp replacements and energy I bought two of the indagro 100 watters.

in my 30x30 tent I have one on for veg and add the second one for flower. Has anyone ever used induction and have you tried the 400 watters?

I don´t think us RIUers have been able to afford these things yet. Bit I think they are the future.
