One of a number of new additions to Griven wide range of exterior architectural projectors, the Kolorglobe 4000 is a MOVING HEAD ultra high power CYM narrow variable single beam colour changer searchlight. This concept in such a high lamp power fixture is almost unique and the combination of moving beam and colour change provides a truly spectacular display that would be a highlight for any permanent or temporary event.
Kolorglobe shares the same lamp and colour change assembly as the static beam Kolorjet, and uses the same Xenon 4000W flicker free lamp with nickel rhodium plated reflector to give an extraordinary light output, further enhanced by the narrow angle beam, zoomable electronically between 1~{!c~} and 16~{!c~}. The CYM colour mixing system gives an enormous range of colour hues, and the unit is weatherproofed to a certified IP44 rating and so is specifically designed for exterior use.
The base unit features brake locking wheels and screw jacks for levelling (assisted by onboard spirit level) and stabilising the unit, transit locks are provided for the pan and tilt movement and the unit is designed for reliability even in tough use, being built from aluminium and galvanised steel with scratch resistant textured polyester black finish.
The high technology lamp and colour changing/zoom optics section from the Kolorjet is already proven, but the same attention to detail has been paid to the new base unit, and, for example, brushless servo motors are used for the pan and tilt movement to ensure high reliability and precision.
On board or remote DMX512 gives access to all functions, which include frost soft edge effect, black out, dimmer, Strobe and standby. Although it is likely that this unit will normally be run by external DMX (8 channels required), on board pre-programmed colour sequences plus a movement demo programme means that the unit could be used stand alone.
The outstanding Griven Kolorglobe has huge creative possibilities, both with architectural and colour changing sky projector applications as well as with live event use, and this wide range of abilities make the unit ideal for rental companies as well as for fixed installation in large scale concepts.

Griven can change the exterior world we know, for a new era of an ever changing dynamic flow of colour and light.
Used Outdoor Architectural Lighting
Outdoor architectural lighting is an integral architectural lighting concept which also follows the same principles characteristic of all well-conceived customized architectural building lighting: appearance, energy efficiency and a balance between the initial and operating costs. Being such, those who undertake projects for outdoor building lighting must take into consideration several factors vital to any other type of building lighting: the inherent psychology and physiology of human light perception and the physics of light production and transmission.
In order to achieve its intended absolute effect, outdoor architectural lighting must sufficiently address vital lighting concerns such as the ratio of functional light to actual energy consumption (output versus intake) and also the actual artfulness that the lighting design registers onto human perception. The purpose of the outdoor lighting must also be taken into consideration. A case in point: regular office buildings and warehouses do not require aesthetically elaborate outdoor lighting, since such structures mostly have to follow their own guidelines on energy consumption and light distribution. But theaters, casinos, and even functional water towers can be made more interesting by creative outdoor architectural lighting installations.
In order for such installations to be perpetually efficient and constantly aesthetic, several factors are to be taken into account, for instance, illumination decrease due to life duty of the lighting fixture, eventual burnout, and constant maintenance against deteriorating elements like dirt and weather components. In conclusion, outdoor architectural lighting is an essential component that should always uphold the principles of aesthetic provision to any structure while holding onto those of architectural lighting design.
