how much light ruins beer

[Tbaz]

i have a secondary that cold crashed in the garage for 3 days, it wasn't directly in the window but the garage had daylight.

How much light direct and/or indirect will ruin a glass carboy with beer 5g

It really doesnt take much, I left some kolsch's on the floor a few months back, and sun shined in and hit them directly, maybe only for a few hours, and they were definetley skunked. That was in direct sunlight though so you might be okay. Just smell it, you will be able to tell immediately if they are skunked or not.
