| Mike, sounds like you have the amboinensis much too close to the lights. Baker says 1000 to 1200 fc. My fluorescent lights are giving me 1500 fc at about a foot or more away. Remember, too much light will stress a Phal until some pathogen comes along and Kapow!, no more Phal. Mine are inexpensive growlights, but that changes the spectrum, not the intensity.
