I have a Bojo, it's fun, but don't think it's doing much to impact fish body condition, rather just entertaining me. Similar maybe to my Green Monster light...blast to watch with a beer on the dock on a warm June evening watching Tstorms in the distance kinda thing. I've been able to observe BCP zooplankton grazing behavior I never would have otherwise...crazy swimming upside down, on their sides, etc. It's also fun to feed YOY BG or FHM around the lights at night - WE, BCP, SMB and YP come in and you can observe them ambushing the forage, which is pretty cool. Recommend them both to anyone who owns a dock - cheap entertainment at the very least.
