Camera Flash
Camera flash units are allowed in carry-on and checked bags; any spare lithium batteries for them must go in carry-on only.

Carry-on details
Allowed. A flash unit itself — whether it takes AA batteries or has a built-in rechargeable pack — has no carry-on restriction.
Checked-bag details
Allowed, but carry-on is recommended for fragile, valuable gear. Any spare batteries (lithium AAs or rechargeable flash battery packs) must be packed in carry-on only, never checked.
Special instructions
If your flash uses a removable lithium battery pack, treat spares exactly like camera batteries: carry-on only, with terminals protected.
