THALAS: range of professional projectors for 70W and 150W HIT-DE-CE discharge lamps with hammered symmetric and asymmetric flood optics and circular anodized spot optics to obtain clean, precise beams. Die cast aluminium body. Thalas is particularly indicated for installations in public places thanks to the class of insulation II and the degree of protection IP66. Thermally tempered safety glass with 10 Joules shock resistance that holds the gasket assuring IP66 protection. The opening of the optical housing for the operations of relamping happens by a rapid snap-in opening and closing system that unblocks the protection glass; the glass remains fixed to the body of the fixture and the relamping operations happen without tools. The opening of the frontal glass sets an emergency switch that stops the electrical connection to the internal components of the fixture to guarantee an additional degree of protection. The electrical components are mounted on an interchanging element.
