Lightning match
From Luchawiki
A lightning match is a one fall match with a ten minute time limit, usually a one on one match. It's a match almost only used on Friday Arena Mexico cards. It was a weekly part of the cards in late 1999 and early 2000, appeared in frequently for the rest of the decade, and brought back as a weekly occurrence in late 2008. It's theoretically a spotlight match to give those who might otherwise not get a chance to have a singles match a big opportunity, but it seldom leads to anything.
CMLL's occasionally used this to follow up on feuds which may not warrant a full three falls match.
