I bought a large stag acro and it was too large to pack. I moved it to my house dry in a rubbermaid tub. I was probably out of water 70 or 80 minutes. No issues. I once burned the tips of a coral under a 400w bulb by leaving the water low for 30 minutes, but that's an extreme. Your lighting shouldn't cause any issues like you describe. Worst case, you could get a lot of slime, but no losses.
