Luke 9:29

Was altered [ε γ ε ν ε τ ο]. Lit., became different. Luke avoids Matthew's word, metamorfwqh, was metamorphosed. He was writing for Greek readers, to whom that word represented the transformations of heathen deities into other forms.

White [λ ε υ κ ο ς]. In classical Greek very indefinite as an expression of color; being used, not only of the whiteness of the snow, but of gray dust. Its original sense is clear. All three evangelists use the word, but combined with different terms. Thus, Matthew, as the light. Mark, stilbonta, glistering (see on Mark 9:3). Luke, ejxastraptwn (only here in New Testament), flashing as with the brilliance of lightning. Rev., dazzling.
