Confused with light set up - Any advice is appreciated

Hi orchid friends!

So this whole growing-under-lights deal is stressing me out. Mainly because I don't know if my orchids are happy, and I want to get the most out of the lights I have installed.

So I recently moved up to 56 degree N, and the lack of sunlight naturally slows the growth of my orchids. I bought two reflective light fixtures with one cool CFL and one warm CFL bulb (1600 lumens) to mitigate this to some extent.

I have 9 phals and 1 oncidium in front of a dim window, the oncidium is placed in the middle and receives more of the light from the CFL's because it's taller, and the phals are scattered around it. So the first week and a half, I was totally burning my orchids.. their leaves started turn red.. so I moved the lights higher. At the moment, the phals are about 15 inches from the centre of the bulbs. The oncidium is closer, about 8-10 inches away from the bulbs. The lights are now on 12 hours a day, even during daytime when they are still receiving low light from the dim window.

My question is, am I using the most out of my lights? Is the set up I have now possibly still harming my orchids? Picture of set up below

It's frustrating that this isn't part of my common sense, but I feel like I have to learn at some point, and what's a better way to learn than making mistakes and asking questions? right?? no?

Any tips would be very helpful!
