Years of the Lamps

In the fiction of J. R. R. Tolkien, the Years of the Lamps are one of the three great time-periods of Arda. They begin shortly after the creation of Arda by the Valar. Their end is marked by Morgoth's destruction of the Two Lamps, the great lights that the Valar raised to illuminate Arda. The Years of the Trees begin after that.
