I haven't used the Big Blue lights although a local instructor friend has and likes them. I use the Sola 1200s and 2000s and like their light field very much. The only downside is their external charging ports which tend toward corrosion and have to be kept clean for proper charging... but then there is almost no risk of flooding due to the internal batteries (vs the Big Blue)[/QUO
Bill I considered Sola lights when looking for a video/focus light because they're compact and have a good reputation, but most people who use them, like yourself, use two because the beam angle is only 60 degrees or so. The Big Blue beam is twice as wide so you only need one, and takes the place of two Solas, and costs about one fourth the price of two Solas. The Big Blue uses the 32650 battery which is widely available.
