I just finished my review of Litepanels' newest 1x1 LED light, the Astra. It's an impressive fixture, with about 4 times the power of previous bi-color units from Litepanels. Litepanels is also making a convenient ecosystem of light-shaping accesories for it, and makes it easy to add DMX networking to any Astra. Plus, the Astra's $1350 street price makes it more competitive with all the 1x1 LED clones that have come out over the last couple of years.
