Dwarven tonic/ent draught take resources to make and are temporal, need to be replenished. The helmet proposed would take one resource investment to provide an infinite duration (or at least a very long duration, since I assume the helmet is breakable in combat).

Also, if you need a long duration of night vision, you would have to pack several unstackable items, clogging your inventory space, reducing the amount of loot you can carry out.
