I'm not sure if the BG3 implementation that Light only affects the equipped weapon is per 5e RAW.
Light, in tabletop anyway, can target any object whose dimensions don't exceed 10ft. You can douse the light by covering it, but covering means unequipping in BG3. If we could cast in on armor it'd always be present, but dousing it would be problematic, if the need should arise.
Ah, thanks. So if we put light on our armour then if we wanted to hide, we'd need to take it off our armour to hide? Would it affect things like invisibility spells?
Apologies, I'm aware I've gone off on a bit of a tangent here, so feel free to ignore!
Lol, in tabletop walking around invisible broadcasting 20 ft. bright light and a further 20 ft. dim light would be a no go for stealth, but who knows given BG3's stealth system. It would be an interesting experiment to execute in game, I believe I'll try next time I'm there. I imagine since you can hide anywhere when invisible in BG3, no checks required, that the Light spell wouldn't even matter. The radiating light would likely impact the rest of party though, if they were trying to hide without the boon of invisibility.
I did play around with this a while back, and IIRC if you are carrying a weapon with Light applied in BG3 then you are always in bright light, so that does make it harder to hide (the game's dodgy line of sight stealth mechanics aside). Of course, with a weapon you can always swap to your other set if you want to be stealthy and pull your lit weapon out when you want to use it, which isn't an option for armour.
I've not played around with Invisibility though so I've just checked and you are right, if you keep the lit weapon equipped it continues to emit light while invisible (!?) which would impact any other party member trying to hide nearby. I don't know what impact it has on NPCs spotting the invisible character without doing some more checking so, like you, I'll do that sometime!
Apologies again to everyone for the diversion, and thank you for the inspiration to think a bit more creatively about how I use Light!
