HLG was going to introduce lensed QBs after rolling them out bare at first but never got around to it, the labor on individual lenses must have been prohibitive to still say “assembled in America” and Vipar managed to find similar lenses in panel form years later, underneath the lenses there’s nothing special going on except a modern red-enhanced LM301B panel halfway between a strip and a board:
Also worth mentioning, they’re definitely making revisions, I’ve bought three the exact same way each a few months apart, two are identical, but the third one now has a breakaway power cable setup, where instead of plugging into the driver directly, there’s a pigtail female lead coming off it, so hanging cables pop open when yanked instead of taking lights down. Nice touch!
