Major antline mess! Here's a guide how to clean it up better:

The turrets don't really need their vision blocked the way you do here because they are just too far away to see you. You can easily portal behind them to defeat them. Useless light bridge.

Even if the issues are fixed, this is just tedious cube collecting and walking around. No real puzzle or challenge here.
