GLP’s Impression Spot One Offers LED Advancements
Posted on Wednesday, March 23rd, 2011
GLP reports that its impression spot one fixture represents a breakthrough in LED technology for today’s entertainment lighting market. While soft edge washlight fixtures such as the original impression from GLP have been around for several years, the challenge was to create a high output performance spot fixture to match. Enter the impression spot one.
To be able to harness the output of sufficient LED sources, with the ability to run them through the optical system of a spot fixture to create an even beam for color mixing (and achieve a focusable area for gobo projections) has been the holy grail of lighting designers since LED became a viable source for entertainment lighting. The company says the impression spot one’s design harnesses that power in an optical system to give it leading edge performance.
The impression spot one features an RGB LED engine with eight or 16-bit control over each color, allowing for delicate color changes or instantaneous color bumps. The spectrum it achieves has been calibrated to be as wide as possible — from soft pastel colors to deep saturated shades, and everything in between. The color field also remains even across the entire beam, no matter the size or sharpness of focus. The electronic control of the LED engine allows full and smooth dimming over the entire range along with fast, solid state intensity snaps and variable speed strobe rates of between one and ten flashes per second.
GLP has removed any kind of base unit — keeping size to a minimum for rigging and transportation — yet still allowing the fixture to be rigged in any orientation.
Beam flexibility is achieved through a motorized optical zoom system with a range of 10 – 32 degrees. Coupled with this is a motorized focus system allowing beam projections to be focused at any range.
Both wheels are fitted with seven interchangeable rotating gobos. All gobos are fully rotating at various DMX controlled speeds and fully indexable with 16 bit precision.
Supplementing these is an additional effects wheel, which allows an oversized gobo to be used in the beam to give animation and movement to the standard gobos at various speeds and directions. The combination of these three wheels gives endless combinations and effects that can be called upon. The soft break up of light through trees, the sensation of drifting water or the harshness of a driving winter rainstorm are all easily achievable along with many, many more.
To control beam size output, the impression spot one features a high speed, fully variable iris – with a speed of just 0.2 seconds from fully open to closed.
Also in the optical effects section of the fixture is a variable speed and bi-directional rotating prism, giving additional effects to the output beam, whether to create additional gobo images, to add an extra dimension to effects from the graphic wheel or to expand the beam even further in its simplest form.
Being an LED based fixture GLP has been able to keep the weight and size of the fixture as low as possible. Matching the impression Meisterstuck in terms of its baseless yoke, the impression spot one weighs just 48.5lbs. The fixture also features a fully auto sensing power supply which operates anywhere from 100-240V at 50/60Hz.
