Still stuck on Light Fantastic, even with that screenshot!
Agreed. Requesting Light Fantastic solution please!
Light Fantastic had me going for quite a while, you do use both mirrors to reflect the light:
SPOILER
Put one mirror 3 blocks above the left fan and the other mirror 4 blocks above the power source. Both should be turned so they are facing the opposite way to the mirror icon on the menu at the bottom.
