Brynäst did not have a good charge before the final series when the corona virus ravaged the team, but it was still they who took the lead.
The Canadian Jalyn Elmes gave them the lead after just under five minutes, but Luleå responded quickly.
Emma Nordin got the pass from Michela Cava and scored after a suspected offside.
Before the period was over, Luleå had increased to 3-1 through the Finnish star duo Ronja Savolainen and Jenni Hiirikoski.
Even 4-1 came through a Finnish and this time it was Noora Tulus.
Luleå continued to impress when Josefine Persson and Cava made it 5-1 and 6-1.
- It is telling for Luleå that they have a huge breadth in the offensive.
There are six different goal scorers, says SVT Sports expert Maria Rooth.
The Finnish goalkeeper in Brynäs, Eveliina Suonpää, did not make his best match and could have taken a couple of shots.
The team also had to do without their star Josefin Bouveng who was missing due to illness.
- It was a tough match, but if we look at the game we have almost more puck than them.
We release incredibly simple goals and it is not possible to do in matches like this, says Brynäs captain Erika Grahm.
The Swedish Championship final is played in the best of five.
The next match is on Saturday, also in Gävle.
Luleå has won the last two Swedish Championship golds, last year the gold was not awarded due to the corona pandemic.
