I travel with a Canon 5D Mark III (0.97 kg) with a 16-35mm f2.8L lens (0.83 kg) and 8" dome (1.36 kg) plus a laptop (1.60 kg) in my carry-on baggage, a Tumi backpack (1.64 kg). With other bits and pieces, the total is 7.6 kg which is doable on most airlines. Additionally I carry a small (laptop size) unconspicuous hand bag that holds four LiIon batteries for my four 80W video lights, this totals 6.5 kg. For most European airlines this is way over the limit, but (knock on wood), I have managed to sneak in with 14 kg of carry-on. But Jools, I guess you could consider British Airways with their luxurious 2x20kg carry-on allowance...
I put the camera housing (3.3 kg) and the extension port (0.49) in the checked-in luggage. For a cave diving trip my checked-in luggage weighs a total of 55-64 kg. This includes everything except tanks and weights.
You can find pictures of my gear here:
and samples of cave and mine video/photo footage here:
As you can see from the samples, it is possible to illuminate fairly large spaces with 32000-100000 lumens if you have a sensitive camera. More is always better.
