Hi,
We recently posted a blog where we measured the amber filter transmission. Here is the blog post: https://iorodeo.com/blogs/news/measuring-emission-spectra-for-the-blue-led-transilluminator
Below is a zoomed in version of the %Transmission graph so you can more clearly see transmission in the wavelengths of 400-550 nm.
The % transmission at 480 nm and 510 nm is about 1%. Transmission doesn't start to increase until around 525 nm approx.
So, this would probably not work for eGFP unfortunately.
