The Beallaras also want more light than the Phals but not as much as some Catts, Dens, or, Oncidiums. We have 2 varieties and the Peggy Ruth Carpenter will take more light than the Marfitch "Howard's Dream". Watch the color of your plants and if it starts getting yellowish, it's getting too much light. You want the Beallaras to be light green - the color of new grass. Most Phals will normally be a darker green than that. Other than the light requirement, the rest of the care can be the same as for your Phal. Good luck!
