Some lighting recommendations please?

Seeing as no one seems to be using the lights I asked about in another thread, I thought I'd ask for more general recommendations for an LED grow light. I've looked through some of the threads here but the problem is a lot of the lights I've seen recommended like Sunblaster don't necessarily publish their PPFD data, which is what I've been trying to use to sift through the myriad of options out there. So I'm hoping to get some recommendations from growers who grow the genera I'm hoping to keep.

I'm planning to grow mostly Cymbidiums, Neofinetias and Phrags, maybe a Phal or Paph or two. I know the last two will need less light than the others so I'm thinking of making a tiered set-up where the high-light loving orchids would be closer to the light than the low-light loving ones. So all the plants would be under one light, as opposed to on separate shelves, each with their own light source. The light from the window is practically negligible so I'm looking for a light I could use year round.

Based on what I've read about PPFD and DLI, I'd need a fixture that would provide at least 250 umol/m^2/s at a reasonable distance from the top "tier" of plants in case that's relevant.

I'd really appreciate any recommendations. If it's easily available in Canada that would be a big plus! Thanks in advance!
