LumoPro

In 2009, LumoPro announced their first venture into an off-camera shoe-mount flash unit, the LP120 Quad-Sync Manual Flash.[1]

Developed in conjunction with the Strobist community, this flash is aimed at professional and amateur photographers alike.

In 2010, LumoPro announced their second generation off-camera shoe-mount flash unit, the LP160 Quad-Sync Manual Flash.[2]

The LP160 is the successor to the LP120. Like its predecessor, it offers 4 ways of synchronization. It has a more power flash (GN 140 in comparison with GN 100 for the LP120), 7 power variations (full to 1/64), faster recycle time (4 sec instead of 6.5 sec), and a metal hotshoe foot. Also has an additional digital slave mode to ignore TTL pre-flashes.[3]

In 2013, LumoPro announced their third generation off-camera shoe-mount flash unit, the LP180 Quad-Sync Manual Flash.[4]

The LP180 carried the feature sets of both the LP120 and LP160 including Quad-Sync, metal hotshoe foot, optical slave, and digital slave that ignores TTL pre-flashes. In addition the legacy features, the LP180 introduces a new sliding lock hotshoe, a 1/4-20 mounting thread on the side of the head for on-axis mounting for umbrellas, and an audible feedback recycle tone.[5]
