A lighting unit includes a first part 3 having a mounting structure 5 for insertion into an aperture in a partition, such as a ceiling or wall, and a second part 9 including at least one solid state lighting device 15 and a heat sink 17. The heat sink is mounted in thermal contact with the solid state lighting device 15 so that heat generated by the solid state lighting device is transferred to the heat sink by conduction. The second part 9 is pivotable with respect to the first part 3 and a seal 21 is provided to seal the first part 3 to the second part 9. The seal 21 may deform to accommodate pivoting movement of the second part 9 with respect to the first part 3. |
