My problem started when I put it too close to the lights and a couple leaves burned to a crisp.
How can this be? Rupiculous Laelias love full sun and, in fact won't bloom without it. Mine is in very bright light (for Northern Michigan) and has put out 2 new growths. I don't have the one you have, but a relative (L. briegeri). I've never heard of burning a rupiculous Laelia in full sun.
