Ok, I just looked up the specs for the most amazing CRT, I still have around, the ultra-flat, digital 17" Apple Studio Display. (It has no label of any kind that I could find.) This one clocks in at 115W, which is not so much in line with what I commented previously. Conversely, the LCD display of the same seies is rated at just 40W at 17". However, as digital connection standards moved on, the only computer you can hook these up to is the G4 Cube.
Generally, CRTs have a sweet point at about 17 or 19 inch. Anything bigger will come at a noticeably loss of quality (due to increasing alignment problems that come with color CRTs), even for the rather expensive ones. (Even a Trinitron is not that sharp at 19" as it is at 17". And I remember a particular 24" Radius display, where you couldn't tell dithered from solid colors.) I wouldn't go above 21", unless you're specialising in large layouts and insist on doing them on a CRT. ;-)
And, as far as I know, the production of commercial CRTs stopped in the 2000s. (But you can still get them, if you're Airbus or a similar manufacturer. [2]) However, for the mere mortals…
