The lumen output on HIDs are kind of misleading. You might have an HPS rated at 95,000 lumens, but that's rated at about a foot away, which is too close for plants most of the time. The lumens drop off substantially every few inches. Getting the light as close to the canopy not only gives the tops of the plants as much intensity as possible, but it also means the leaves below, and underneath, are getting adequate light as well.
As far as your LED and clones, I just don't have any experience. But clones need much less than 30k. I only measure about 3500 lumens with my clones.
I would invest in a LUX meter instead of using your phone.
