The Lumedyne HRF1 Ring Flash works on almost all Lumedyne Power Packs. It has 12 LED modeling lights that have a 20' range, for focusing and previewing in the viewfinder prior to exposure.
This ring flash is extemely efficient. In tests, a lens aperture of f/8 was used successully, @ 200 ISO, @ only 12 watt/seconds, from a distance of 4 - 5 feet.
- This ring flash features Lumedyne electronics and flashtube in a Hensel designed reflector and assembly.
- Sturdy universal camera mount, lightweight plastic body
- Coiled pack to head cord extends from 3 - 7 feet.
- The LED modeling lights put out a little less than 25 watts tungsten equivalent, but use less than half of the battery energy as a 25 watt modeling light.
Note:As of late August, 2006, Lumedyne has not confirmed compatibility with the #068 and the Action Packs.
