Etymologically, the entry records: The group can be viewed as acting on a doubly infinite sequence of street lamps …,l_-2,l_-1,l_0,l_1,l_2,l_3,… each of which may be on or off, with a lamplighter standing at some lamp l_k. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is lamplighter group, spelled L-A-M-P-L-I-G-H-T-E-R- -G-R-O-U-P, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
