Durham secured their first win of the season as they finally saw off dogged Lancashire's resistance under the floodlights at Chester-le-Street.
But, after declaring on their overnight 239-4 to set a target of 325, it took until after tea to clinch a 73-run win.
It looked like an early finish when Lancashire slid to 97-5 before lunch.
But Liam Livingstone's unbeaten 60 was enough to delay promoted Lancashire's first defeat of the season before eventually being bowled out for 251.
He shared a 67-run stand for the sixth wicket with wicketkeeper Alex Davies (39), then another of 56 for the ninth wicket with Kyle Jarvis (28).
But, despite 41 from opener Karl Brown, it was in the morning session when Lancashire lost their way, Brydon Carse taking two of his three wickets.
Perhaps concerned about the weather forecast, and the threat of rain, Collingwood opted not to bat on.
And, given the rearguard action Lancashire's tail enders displayed in conditions gloomy enough to warrant switching the lights on, his decision to set only 325 to win ultimately proved correct.
James Weighell also weighed in with three wickets, before former England seamer Graham Onions trimmed Simon Kerrigan's off stump to finish the job.
Durham now travel to Edgbaston to face Warwickshire for their next County Championship Division One fixture on Sunday, while Lancashire host last season's Division Two title rivals Surrey at Old Trafford.
Durham coach Jon Lewis:
"It took a bit of courage to declare overnight, so all credit to Paul Collingwood for that.
"It was still a decent pitch and we knew we would have to fight for every wicket.
"It was an excellent performance by the pack of bowlers."
Lancashire coach Ashley Giles:
"We knew it would be tough because the pitch deteriorated over the four days, which you would expect.
"But the way we went about it was really positive and, while we never like to lose, we don't need to be too down.
"There's certainly things we can improve on, but we need to dust ourselves down and go again."
