After a disasterous experiment with a red filter on my light several years back, I googled a marine biologist who'd done some research into lobster's optical acuity and I emailed him for some info.

He said lobsters have very good night vision (as you'd expect), mostly using the shorter (bluer) wavelengths of the spectrum. In other words, they couldn't see our red lights but because they weren't blinded, they could see us coming and spooked.

He suggested white light works better because it overwhelms their optical receptors and they can't see a thing, like a deer in the headlights.

I find it's best to avoid shining the light directly on them until I get close; then I point the light from one direction and grab from the opposite direction.

Also, when I see a bug in the distance, I scan around the area for others before making the grab. Where there's one, there's usually more and often bigger ones.

Lastly, some say HIDs don't work well for lobster hunting but I find they allow me to see substantially further, so I can cover a lot more ground with less effort. I don't lose many bugs due to spooking them -- mostly just to losing my lobster bag :-(.
