I'd reccomend putting them behind the Bitcoin logo, and then opening to a BTCPay server or smth that has both an onchain and lightning logo. It avoids confusion and is far more recognizable than just the lightning bolt.

The one concern is that someone with an LN wallet comes along who sees the BTC logo and doesn't click bc they don't want to mess with onchain that day, but doesn't realize that LN is behind that as well.
