Aircraft
In preparation for water service toward the end of cruise; I grabbed a cold cup sleeve from the AFT galley overhead compartment on Aircraft right. The sleeve of cups was noticeably warm. Using the back of my hand; I felt the bottom of the compartment and recognized the surface directly over the galley light that is mounted under the compartment was extremely warm. Upon further inspection; the surface above all lights in the AFT galley that were mounted to illuminate the counter area were extremely warm. (Note: By this stage in flight; the lights had been on constantly for multiple hours.) I shared this observation with my FA (Flight Attendant) Crew and they said it wasn't uncommon for the surface to be so warm within this gallery configuration. While we didn't determine any imminent danger; the temperatures generated were remarkable and concerning.Determine if the extreme temperatures being produced are a potential hazard (melting plastics; burned fingers; fires; etc); and if so; mitigate and/or eliminate the hazard. Determine (perhaps in conjunction with the lighting manufacturer) what causes the increased temperatures: type of bulb; duration of lights being used; type of material around the bulb; etc. Investigate the lighting on this specific tail number. Investigate the lighting on all the aircraft with this same galley interior. Make a plan. Execute plan. Communicate any new actions or responsibilities FAs.
B737-800 Flight Attendant reported galley lighting configuration may cause overheat condition near light fixtures.
