The RCM LED – shedding new light

Voltex Lighting has taken Mellow light to an entirely new level with the introduction of the RCM LED. This has been achieved by optimising the ‘mellow light’ concept, which is ultimately one of perception, the result of which is a visual environment that appears brighter at lower levels of illuminance. Mellow light fixtures produce high vertical, even horizontal illuminance making it easier for people to see, which is why it appears brighter when compared to dark light fixtures. Dark light or louvered light fixtures cre- ate numerous light and dark patches that can cause eye fatigue.These contrasts force the eye to adapt continually between a back- drop of light and dark contrasts.With a dark light fixture little light emits from the fixture; the opposite applies to Mellow Lights. With the new RCM LED these con- trasts are eliminated and consistent high levels of illuminance are achieved. A higher

level of eye comfort is provided because the LEDs are totally masked by the optic and soft diffused light is achieved through high angle brightness controlled material. Studies have shown that the optimum level of illuminance in terms of productiv- ity, lies somewhere between 350 and 400 lux and the norm is to design to 500 lux. With the RCM LED it is possible to design using fewer luminaires yet maintain an environment where the perception of light is visually brighter. The RCM offers the ultimate in com- fort and brightness as well as a greatly improved aesthetic, with its stylish hi-tech appearance.Technically it offers maximum performance using high transmission material with even light diffusion over the entire optic with 87% efficiency, 118 lm/W efficacy and high colour rendering. Says GLP Inc president, Mark Ravenhill. “If you want to mimic molefays, you can; if you want to create groundrows, you can; if you want to make a little 2-Lite or a stadium style light fitting, then you can — and you still have full control over each head individually.” Control for the Atom heads is via an Atom PSU controller — commencing with a 12-way, but with a 6-way and other models to follow. The PSU supplies power and data down a single 4 pin XLR cable to each Atom head. “Since it uses the same format as industry standard colour scroller cable, the rental houses who have stopped using colour changers can now repurpose all that existing cable and infrastruc- ture — meaning less investment for them and reduction of overall environmental impact of the Atom,” says Ravenhill. Rounding out the feature set, the impression X4 Atom contains other advanced features, in- cluding adjustable flicker free control, beautiful colour mixing, smooth dimming without any colour shift and variable speed strobe.

The mighty Atom

If the atom is the basic building block of all mat- ter, it can be argued that the sheer versatility of GLP’s new impression X4 Atom — which will occupy a unique position in the marketplace — will provide a fundamental tool for all lighting disciplines. Size matters, and the power of the Atom comes from a body that measures less than 16 cm long and weighs just 1.3 kg. Within that body is a high powered 15WRGBWLED source that emits a bright beam with even colour distribution across a full spectrum. Making the Atom unique in its class is a motorised zoom inside that gives a mighty 9:1 ratio; running from 3.5°-34° and adding a huge amount of flexibility. Increasing its usability in multiple applications is the IP65 rating that the unit carries, allowing it to be used all year round indoors or out. Furthermore, the X4 Atom features a clever interlock mechanism that allows units to be built into different configurations quickly and easily. It is therefore set to benefit multiple applica- tions fromTV and film, to corporate events, set lighting and special events. Also benefitting will be concert touring stages, truss systems and architectural elements, as the interlock system quickly turns single fixtures into 4-Lites, 8-Lites or any other shape.
