Luchnos is a lamp, used for a light set out to illuminate and for figures of persons or sources that give light.

The term most often denotes an ordinary lamp that is lit, kept burning, placed visibly, or whose light is absent; it also appears in comparisons and predicates that portray an eye, a person, a prophetic word, or the Lamb as a source of light.

1. A lit lamp used to give light · dominant

   In Matthew 5:15 the accusative singular occurs in the action of lighting it and setting it on a lampstand so it gives light in the house. Luke 8:16 and Luke 11:33 likewise contrast covering or concealing a lit lamp with placing it where entrants can see; Luke 15:8 places it in a woman's search through her house.

2. The eye described as the body's lamp · common

   In Matthew 6:22 and Luke 11:34, the nominative singular stands in the clause identifying the eye as the body's lamp, followed by the contrast between a sound eye and brightness or an evil eye and darkness. Luke 11:36 continues the comparison by describing illumination from the lamp.

3. A figurative source of shining light · common

   John 5:35 calls a person a burning and shining lamp, while 2 Peter 1:19 compares attention to the prophetic word with attention to a lamp shining in a dingy place. Revelation 21:23 names the Lamb as the city's lamp in a clause about the city's light.

In the Anselm Project Bible: The APB regularly uses “lamp” in the supplied verses, including lighting, burning, shining, and placement on a lampstand; it also has “light of lamp” in Revelation 18:23 and Revelation 22:5. These renderings confirm the verse contexts rather than assigning a separate English equivalent in every clause.
