Question about Philips Wake-Up Light

I can't tell you in lumens because I don't have the corresponding test device. In the wake-up function, the lowest level is such that you only notice it when your eyes are open. In the lamp function (i.e. the lamp is consciously switched on, e.g. for reading), the lowest level is perceptible when the eyes are closed. If you tell me a test procedure, I will be happy to try it out for you.
