Your patron gives you a mystical lantern. You can freely decide on the appearance and type of the lantern, but it always has one feature that marks it as special. Maybe the flame is green or another unusual color, or it makes a peculiar smell as it burns. The lantern doesn't need oil to burn, and you can light or extinguish the flame using your object interaction without using a tinderbox. If you ever lose the lantern, you can summon it as a bonus action. When you cast a warlock spell of first level or higher, you can choose to store it in the lantern, saving its effects for later. The spell stays in the lantern until you finish a long rest, at which point the spell's energy dissipates. Until the spell dissipates, you can cast the spell stored in the lantern, using the spells normal casting time. Once you cast the spell stored in the lantern, you can't store another spell in it until you finish a long rest.
Since Warlocks don't get many spell slots, I thought it would be interesting to give them a way to store spells for later.
The pact seems rather fun, but also kind of prone to abuse. Depends on how much a DM allows players to Short Rest, but in many games where Short Rests are given quite freely this would essentially just give the Warlock an extra spell cast each rest. Although with the limitation that they need to choose the spell in advance, which is fun; similar to how the Cartomancer feat from Tasha's works.
For the Invocation, that is borderline just Truesight, which is already available as a level 15 invocation; Witch Sight. This version does have the prerequisite of having Pact of the Lantern, but otherwise just gives you nearly the same effects as a level 15 invocation 4 levels earlier. I would recommend maybe rethinking that.
Ah yes missed that last line I suppose... Honestly, might be a little on the weak side in that case, compared to the other Pact invocations. Maybe a middle ground of allowing it a number of times equal to Charisma modifier or Proficiency Bonus?
Most of the Pact Boons are more for utility/flavor than anything else. Pact of the Chain gets you a fancy familiar that can attack, which doesn't do that much, Pact of the Tome gets you a bit more utility with cantrips, and Pact of the Blade gets you a weapon that's always worse than Eldritch Blast. I think mine is just fine.
As a bonus action, you can deal damage equal to your Charisma modifier to each creature within the Bright Light created by your lantern. You can choose the damage type, but it must be related to your patron in some way. For example, a Fiend's lantern will probably do Fire damage, and the lantern of a Great Old One or Archfey might do psychic damage.
What do you think?

The pact of the lantern is once per long rest, and I forgot about witch sight. Thanks for the input.

I have an invocation for the pact boon.
