Opti-V PGF-20 renders the most realistic flame effect possible through a unique combination of real fire footage and a clever illusory technique. Flickering flames dance on a vertical fuel bed with an almost three dimensional depth of field thanks to the system's two High Definition LCD screen, all accessible via remote control. The larger of the Opti-V range combines the audio element of crackling logs, the illusion of a real fire - and all at the running cost of a light bulb.
