Day/Night test cricket

Wouldn't it be fun to watch the final hours of test cricket at night after coming home from work.

Keeping in mind the amount of damage T20 is causing to Test Cricket and as popularity of test cricket is decreasing among spectators , it seems to be a better idea to implement day/night test cricket.

Cricket Australia has been very keen to introduce the day and night tests. But the major problem in this kind of tests is to find a ball that can be used for 80 overs and make sure that it does not lose its visibility under any the circumstances.

Positive points :

1. There won't be any instances of game being stopped due to bad light.
2. This move would allow more people to watch at grounds and on television.
3. Hot and humid climates can be avoided.
4. Bad light would no more be a problem.

Negative Points:

1. Teams bowling at night may have problems with the ball. But as it is a 5-day game, it won't effect the game much as the other team may also get into the same situation to bowl during the night.
2. Changing the ball to suit the day/night cricket.
3. Color of the ball.
4. Fielding may be difficult in presence of dew factor. There will be a lot mis-fields as the ball easily slips away from hands.

2nd and 3rd problems are solved by Cricket Australia. It has been trying to host Test matches at nights for the long time. CA commissioned the CSIRO in July to manufacture a revolutionary all-conditions ball suitable for Tests in Australia played from 1pm to 9pm. Cricket Australia is assured that it is possible to develop a suitable ball for day-night tests.

Australia and Pakistan are going to become the first teams to play a night Test next November in Adelaide according to a report.

I think a bit of thinking should go in before putting this idea into practice.

any thoughts?
