Offices are usually brightly lit, and London office buildings are frequently brightly lit as you describe.
However, the St George Tower is not an office building but a partially constructed residential block.
The strip lights to which you refer can be seen in the pictures above and below.
My post to which you refer was in answer to a previous poster who suggested that obstacles should be lit at intervals rather than just at the top. My mention of the internal lighting was simply an aside.
