Does this sentence work and make sense?

I would say that the adjective "effulgent" would most often be used as an attributive adjective. In other words, preceding the noun it describes. I don't think it would usually be used in such a simple sentence, or to describe a person in general. I would not expect to hear the word "effulgent" in everyday English -- which is what your sentence sounds like otherwise.

That's my two cent

I have to say, I have never seen this word before in my life. I thought it was a typo for "effluent" (and you probably would be after you won the lottery).

I've never won the lottery either, nor is my name Amy.

One of the places that word is likely to turn up is on a GRE vocabulary list. (I think that is actually how I first came across it.)

Webster's on-line dictionary cites its frequency as 6 times in 100 million, and, on a scale of 1 (most frequent) to 700,000 (rarest), it ranks around 144,000.
It is mostly used to describe objects that are naturally luminous or reflecting light - the sun and moon, bright flowers, leaves, etc.

I'm still waiting to strike the jackpot.

Interesting. I learned a related word, albedo, when I was learning about sustainable design/construction.



Thanks!
