I've checked several times around there and found no answer. Everyone I've talked to has had different answers for me, but none of them allow me to use it. I've tried with a power block, without one, tried turning all the lamps on via the command (as stated above) and tried several times after restarting. I'm beginning to think that either I'm glitched or it's just not an option and was put into the construction simply because it's classified as a lamp. That or as a horrible April Fool's prank.
