The spell ends if you cast it again or dismiss it as an action. so when you cast it on a second object, the first spell ends. I think.
but if your group was made of bards, clerics, sorcerers and wizards, everyone could do it ... ^^
alternatively there's this feat:
Choose a class: bard, cleric, druid, sorcerer, warlock, or wizard. You learn two cantrips of your choice from that class’s spell list.
In addition, choose one 1st-level spell from that same list. You learn that spell and can cast it at its lowest level. Once you cast it, you must finish a long rest before you can cast it again.
Your spellcasting ability for these spells depends on the class you chose: Charisma for bard, sorcerer, or warlock; Wisdom for cleric or druid; or Intelligence for wizard.
So Humans (variant) could learn Light as any class...
Imaging a Barbarian who can cast
