Lumens Factory XP-L vs 319A vs 319B

[adam38654]

I am looking for a 3-4.2v single cell bulb for my 3p clone. Would a 700/800 lumen 319a/b be more efficent than a 550 lumen XP-L in 30% mode? I would only use 100% for short burst.

I have their 319a 80CRI drop in for a 6P and for a M961. Both are gorgeous. Neither are anywhere close to 700 lumens.
