Lights and interior .com - I doubt if anyone searches for this exact phrase.
Since the phrasing is awkward, you can't even say it's brandable.
Candid closet. com - normally when candid modifies a noun, it would be "picture" or "conversation".
People don't have / buy / search for candid closets.
And, if one were to name a business Candid Closet, it would be tricky for the public to imagine what this business is about.
$RegFee for both.
