Perhaps, but if they are attracted to their prey by luminescence, they might think that this big light might be a big meal. An octopus will crawl over the ocean floor, but not a squid. Smaller squid dart around in the water, but we don't know if the giant squid do. That would really be something, a 60-foot animal shooting through the water. Again, we don't know.
Some people think that they just float around waiting to encounter prey.
Others think they're more aggressive. All of the dead ones that have washed up have had empty stomachs, so we don't even know what they eat. The giant squid has no claws. Yes, but the sperm whale is not an especially fast swimmer. Another thing we don't know is how the sperm whale hunts the giant squid.
