Video, Laser, Sound, LED lighting, fog and water screens have been implemented to
add additional attraction and explanatory media to the cave. The European Union
supported this project with subsidies, and HB-Laser was chosen as project partner
for the implementation, together with their local partner Factor in Sofia, Bulgaria.

Making a large scale, complex multimedia installation of this scale is very difficult:
The high humidity and in some cases direct water spray requires highly protected
equipment, which applies for the video technology, lighting equipment, lasers as
well as speaker systems.

HB-Laser not only implemented the technical equipment, but was also responsible
for the complete multimedia control and wiring of the whole installation. Five main
control boxes were installed (IP67 with air conditioning) to handle multimedia
components: A 6m water screen has been installed in the main hall, projections
were done with 7000 ANSI lumens video projector and two HB-Laser LC-851 RGB
5.5 IP68 waterproof laser systems. In addition to that, 110 RGBW LED spots and
wash lights have been installed – all IP68 waterproof. The spectacular lighting setup
was flanked by a powerful PA speaker system that was used for the show as well as
for explanatory purposes.

The side halls and tunnels were equipped with additional 120 RGBW LED spots and
wash lights – as well as with a HB-Laser LC-851 RGB 5.5 IP68 waterproof laser
system for creating a volcano simulation. As special highlight a mystical scenario
was created using a 1m water screen element in combination with a 3000 ANSI
lumens projector, showing the fairy of the Lake of Desire.

The German company HB-Laser is specialized in show laser light technology as well
as in multimedia project implementations. They plan, design and implement custom
