Varytec Theater Spot 300/500 Fresnel

Bought 4 of these as bundles (with lamp and barn doors) - which was much cheaper than buying individually. The Fresnel was not quite as bright as expected but was easy to setup and install. They have a easy mechanism for moving the lamp backwards and forwards using a kind of screw thread which you turn via a know at the back for focusing.

The only problem encountered so far is that the building they have been installed in has very sensitive ion smoke detectors which set off the fire alarms after all 4 were left on maximum brightness of about 25 minutes! I think this is probably due to them being new as there were no visible issues. Hopefully that will not continue to be the case over time.

Other than that they are a good basic lantern.
