I am in no way endorsing the following at all so please don't do this but. . .

Couldn't someone just download a client such as Nodus and use Fullbright?

 

Donating for ext commads gives you /ptime which does the same thing or get a fullbright mod, as they are not illegal at this time, no need for yet another plugin doing what can already be done....

 

cjb is currently legal and has a nightvision feature, as well as other useful things all in one package. I tried nodus once, and didn't feel safe using on the server. Not to mention nodus is now illegal to have and will result in a ban if you are caught using it.

 

Nodus is illegal, I don't recommend it.

CJB and Gammbright are good mods for fullbright.

 

Also i sell night vision potions for 20
