I was going to go for the same advice, opp. I have a philo that is similar in color and leaf form, only mine has red stems. It's growing outside in full shade, but full shade here in Florida still has lots of good UV's bouncing around.
(I am a redhead, and I can get sunburnt in the shade here.)
For a tropical plant growing indoors, it's always better to give it too much light than not enough. It will tell you when there's too much light without dying, but too little and it will just quietly starve to death.
