I did not see your message until now. I grow hundreds of staghorns including the 'Lemoinei'. Though I love for my stags to get a couple of hours of early morning or late afternoon sun, I don't give any of my stags sun from 11:00 AM until 4:00 PM. The vast majority of staghorns grow in trees and the canopy of leaves protect them from direct sun. I would suggest you grow it the same as I do. I also suggest you mount that plant and grow it as it does in nature. Once your staghorn has recovered and is fully established, you can gradually increase the amount of sunlight. But since you don't state where you live, I really don't know just how much sun you can acclimate it to.
