Easily carried lamp (5)
I believe the answer is:
light
'lamp' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for light that I've seen before include "guide in the dark" , "Undemanding; crossword answer" , "Not dark; not heavy" , "Settle" , "Form of radiation - not serious" .)
