All of the lanterns in the Harmony series have a fully integrated housing of finned, extruded sides and interlocking pressure die-castings including internal colour runners. Rear grab handle is fitted as standard. The alloy fork is adjustable in height and also adjustable throughout the whole length.
The Harmony series embody new safety features but in a way that these do not inhibit practicability. These include a power connector which automatically separates when the rear-hinged, full width internal access is opened, a safety bond anchorage on the housing, sprung safety clips over both the colour frame and the gate runners, and an integral 25mm mesh lens guard.
1982 Upgrades
Optical improvements were made to this range in 1982. These improved beam distribution quality both at peaky and flat field settings. In general terms the half peak angle is greater and the peak value is reduced, resulting in a much cleaner beam.
What are the differences?
On the Harmony 12, 22 and 15/28, a new reflector with annular rings was mounted from the rear casting (originally a different reflector was mounted from the front). On the Harmony 22/40 it is more difficult to identify visually because a different reflector with a special surface texture over part was mounted from the front.
