Lighting tubeful (4)

Ross

I believe the answer is:

neon

(Other definitions for neon that I've seen before include "Type of lighting" , "None like bright city light" , "One of the six inert gasses" , "'Chemical element, often used in lights (4)'" , "Noble gas used in illuminated signs" .)

I've seen this clue in The New York Times.
