What's the point of a 35w 1300 lumen 6000hr slow warmup white sodium lamp for £50? A CFL has better efficacy, faster warmup, longer life, instant onoffability and a fraction the price.

If you need it, the 83% CRI makes it worth the effort and money. If you
don't need it, then a CFL will indeed do the job.

CFLs are normally in the 80s% CRI.

Shop lighting designers are a different breed to anyone else and would
get all precious if they couldn't get what they wanted.
Also, there's an installed base of these things so notwithstanding the
suitability or otherwise of the horrible CFL ****e, it's necessary to
replace like with like as what shopowner wants to rip all the fitting
down to put some utter ****e lighting in?
