Yes...and you did the right thing!
And good thing you already knew about Chams, CBCAMO.
So you knew something just wasn't right with what he was telling you.
Imagine if you were a total newbie and had taken his advice ? !?
In a relatively short time you would have had a stunted sickly cham on its way out suffering from MBD.
And yes.. yes...I know anyone can make an honest mistake and give advice that misses the mark.
I am still learning things every day too!
But what he was recommending to you was SO FAR off the mark...
that it just boggled my mind.
What struck me in this example was not only does he sound poorly educated on reptile lighting.
(And remember: it is his Job and responsibility to be at least somewhat competent since he is dispensing advice as an authority figure and professional and (animals) lives depend on it.)
But it appears he also did not "get" what a 50/50 light was designed for as far as reef tanks were concerned either.
IE: what the "50/50" meant as far as that light's spectrum was concerned and what it was designed to simulate.
Because if he knew what the spectrum that reef tank lamp is trying to recreate - he would have known what a poor choice that would be for a terrestrial animal set up in the first place.
So in my book that's a Double Whammy.
(having owned 2 pet stores in the past 30 years, I have a low tolerance for that sort of thing.)
Cheers!

And best of luck.
Sincerely,
Todd
