The Electron Excitation Chamber(from here on, EEC) isn't behaving the way one would expect it to based on the contents of the in-game documentation. No light bridge is produced when two directly adjacent EECs are hit with parallel cyan laser beams, UNLESS the beams are colored using the creative cyan filter. Whether its cyan light from passing through a block of cyan stained glass(which doesn't attract entities), or a cyan laser produced with the Light Beam Coalescing Cube (which, I confirmed, attracts entities), no light bridge results. Additionally, I have discovered that there are cases where a light bridge won't (...properly) form even with the creative cyan filter. Admittedly, my image doesn't give a clear view of what I did to make it happen, but I'll just tell you that the setup is 4 rows of:
creative laser->creative cyan filter-> 2 lenses-> any number of air blocks(within reason :p) ->EEC

As you can see, what happens in that case is...odd, to say the least. And just to be sure, I did check, and it isn't just a case of the bridge not rendering as it should; The 1 by 4 area directly in front of the EECs that looks like a light bridge is solid, and the part that looks like a cyan laser beam are not solid, and pull entities towards the lasers(because they are, in fact, somehow still cyan laser beams).

My guess is that once the first block is converted to a light bridge, it stops checking the lasers because the laser isn't actually hitting the EEC. A check would be needed for that, I suppose? maybe in the light bridge block itself? would need a direction (east-west, north-south, up-down?) to prevent creating corners, but ah well.

And about it not working unless the lasers are colored using the creative filters?

Sorry, but refraction 1 is discontinued. Refraction 2 is going to be a thing in the future however. Super sorry. :(

Welp, I look forward to seeing it. Will it be in 1.10.2 at all, or will it only be for future versions?
