The International Cricket Council is ready to consider six-day Test matches in Pakistan because of the amount of overs being lost to bad light.
The lights at the Gaddafi Stadium have proved ineffective
The use of floodlights has made little difference to the problem, which only applies during the winter months.
In the current Test between Pakistan and England in Lahore, 13 overs were lost on the first day and 19 in the final session on day one.
"It is something we have to look at," said ICC chief executive Malcolm Speed.
"Getting a full quota of overs in a Test is a priority for us."
Around 60 overs were lost during the second Pakistan v England match in Faisalabad.
But Pakistan Cricket Board chairman Shaharyar Khan said they little option regarding the scheduling of matches.
"We can't have our cricket season at any other time of the year. We have to play our season from October to April.
"Playing at any other time would not be fair to visiting teams because of the hot weather," he explained.
"This seems to me the obvious solution."
The most recent six-day Test occurred during the ICC Super Series in Australia in October.
Pakistan have never staged six-day games on home soil, although the team did play five on a 1958 tour to the West Indies.
And Khan confirmed they would be willing to consider extending the length of home Tests to ensure the regulation 450 overs are possible.
