Well , you can run a 26W compact in a standard e27 (plastic) socket. These are hard to find ( as I discovered when I wanted a sparky to replace my old corroded 20 year old back outdoor light socket with an e27 socket rather than a bayonet fitting ( easier to replace and more secure ).
The dome fitings (clamp lights) available here (in Australia from pet shops) seem to be all ceramic , better IMO.
This gives the buyer the option of fitting a hot running globe if they choose to ie a domestic floodglobe, a reptile neodymium flood, an mvb or a che in the fitting.
Of cause you could have visited a Kmart or BigW and bought a standard clamp lamp (bedlamp) . I don't like your chance of finding one with a e27 type socket though.
Took a look for domestic ready wired e27 fittings , found one

Bunnings have no e27 fittings listed that can be hung pendulum style , the only one they list is
https://www.bunnings.com.au/deta-e27-ed ... r_p4430709 and LRA have

A sparky will charge you $150 just put a foot in the door (if you can find one interested in doing the job).
I've never seen any CFB UVB bayonet fitting globes ( offered by Exo Terra , Zoo Med or Arcadia ) .So no not really ripped off.
