Green Light, Disruptive to Flower or Not?

Hey guys, got a quick question here regarding light leaks. I've got very minute amounts of light penetrating foam weatherstripping ever so slightly, to the point where you can see a glow through it from the inside of the room, but not to the point where rays of light are cast upon the floor of the grow room. I'm wondering is this enough light to interrupt the flowering cycle? And if so where can I find a 4ft T12 green light I could only find the light sleeves and am not sure if these work in the same way as a typical green light does. I'm quite upset things aren't as light tight as I was hoping, but I'm also hoping there might be a simple fix to this.

Thanks all for the help.
