I picked up a staghorn in September. It’s currently inside at night and outside during the day, except for days it doesn’t get above 55F outside. It gets eastern exposure with hours of direct sun in the morning, then half a day of 50% sun, followed by very bright shade with indirect light around 500-1000fc. It’s a very happy plant that’s overdue for a repotting. Replicating that with lights indoors would probably need 2,500fc minimum?
That was my thinking, something like 12-14h under lights at a constant 2,000-3,000fc or 250 umol/m2/s

Don’t forget that “something like 12-14h under lights at a constant 2,000-3,000fc” is equivalent to natural daylight reaching 4000-6000 fc, which is too high for a staghorn.
