George Dockrell and Gary Wilson formally received the Interpro trophies for the 2019 season during Ireland's five-day training camp at YMCA.
Lightning won both the 50-over and Championship titles under new Head Coach Nigel Jones, and have now won 17 of the 21 titles on offer since the interpros were revamped and revived in 2013.
Skipper George Dockrell spoke about just what makes the Lightning brand so successful: "We've got some very good cricketers who fill roles within our squad and a lot of depth as well - when new guys come in they come in to do a job within the team.
"We've also had fantastic structures as well, first with Albie [Albert van der Merwe] and now Nigel Jones coming in as Head Coach - we've had some great guys supporting us through it.
"This is the first year with Jonesy and every coach brings something a little bit different. Albie was great, and a new coach often brings in a new set of eyes, sometimes they come at things from a little bit of a different perspective.”
Leinster was prevented from completing the treble by Northern Knights, who managed to clinch the T20 trophy thanks to impressive displays in Dublin as the NW Festival was washed out on all three days.
Their captain Gary Wilson, captain of the Northern Knights team, was playing in his first full season back since his return from playing 12 years in English county cricket.
“I don't think it was just the T20 competition that we performed well as a squad - it was disappointing that we couldn't get over the line in the three-day championship, and we maybe let ourselves down once or twice during the one-day comp, but I think our performances are the product of a lot of hard work put in by the guys and a lot of work behind-the-scenes that Simon Johnston has put in over the years," said Wilson.
“While it was obviously frustrating with the weather this year, I've been very impressed with the standard of the Series and the way the whole competition has been run.
“From my perspective, the Inter-Pro competition is a great pathway into the international side, not the only pathway - as club cricket is still important - but if you are playing well at club cricket level then hopefully you'll get picked for the provincial side, and if you play well at provincial level then there's a chance you will get selected for the Wolves and then Ireland. And we've seen that in recent times. The more you can put your hand up in Inter-Pro cricket now, the more chance you have to get selected for the international side.”
