I'd like to try to answer, because I'm an enthusiast.. but don't want to come across with a certainty as the tools to examine it aren't at my disposal. But very severe cells .. supercell that are potentially tornadic in nature have less lighting, but more extreme strikes, they cycle up and down, stay very compact ... they can 'float' over your head and yet a mile away drop a severe hail core, blow the cobwebs away with very strong winds and drop a funnel. I have my eye on it.
