Lighting the way
The debate is over – LED lighting products are now a fixture in the kit list of any lighting designer worth their salt. S+S looks at a few of the latest releases on the LED market.

Chroma-Q - Color Force 72 / 48
New from Chroma-Q is the Color Force 72 / 48 range of 1.18 metre, 12,000 lumens output and 1.76 metre 8,000 lumens output LED battens. Chroma-Q says they provide super bright light output and smooth, uniform coverage for washing areas up to eight metres high and those lucky enough to have tested them tend to agree. Word on the street is that compared it to a conventional tungsten multi-cell cyc light, the Color Force works out better in almost every respect and is ideal for lighting cycloramas or as a border light.

I-PIX BB 2x2 LED
i-Pix BB 2x2 LED fixtures made their live event debut in June on Glastonbury’s Pyramid Stage that hosted Stevie Wonder among others. The 2x2’s are a square four cell self-contained fixture made up of two BB2 units with removable fronts for the option of mixing up the optical systems.

They include 10 and 20 degree optics as well as two additional beam angles. Twenty were rigged on three of the overhead trusses and used for camera candy and general stage washing for day and night sessions due to their brightness and the smooth quality of the light output.

Philips Lumileds – 2700 and 3000 CCT LUXEON Rebel
Two new additions to Phillips’ Rebel range, these LEDs have correlated colour temperatures of 2700k and 3000k and are said to offer the smallest white binning space in the industry as well as minimal colour over angle variation, with CRIs of 85.

The new emitters use thin film flip chips and Lumiramic phosphor technology that provides consistent colour and tint across a range of viewing angles. Similar versions were used on a mobile Vatican podium, used by Pope Benedict XVI to address congregations outside the holy city – a solid endorsement if there ever was one!

ADB Lighting Technologies - ALC4 CYC LED
ADB’s newest addition, a modular LED Cyclorama light, uses four RGB and white LED light sources.

The ALC4’s are currently featuring heavily on French electro-synth and event spectacular pioneer Jean Michel Jerre’s world tour. Lighting Designer Ignace D’Haese is using 48 of the ALC4’s to light a giant 30 by nine metre cyclorama that forms the stage backdrop, with 24 along the top and 24 along the bottom edge.

One ALC4 can deliver the equivalent of 1250 watts of halogen power, yet only consumes 160 watts, according to the manufacturer. The Lexel LED module is colour-tuneable (RGBW) and the light is mixed in a mixing chamber for homogeneous light output. An internal feedback system enhances colour consistency.

The system can be controlled by DMX in different modes, including colour-tuneable RGB mode or in a white-tuneable CCT mode. In the CCT mode, the white colour temperature can be controlled from 2700K to 6500K. The colour rendering index (CRI) is above 80.

Chauvet - SparkliteLED Drape and SparkliteLED Controller
Want to create a twinkling night sky, a wall of strobing purple, or an expanse of glowing azure? Chauvet has just released a pair of products to do just that.

The SparkliteLED drape is a black fabric panel studded with 128 0.25 watt, five millimetre LED lights fitted into eight zones, and can be attached to others to create a field of colour or theatre curtain.

The drapes are then operated by the SparkliteLED Controller that can run independently or by 12 or 24 channels of DMX control. You can pick from built-in programmes or control up to eight zones (16 LEDs per zone) of each drape using features like configurable LED sparking direction and speed and group sparking cross fade time.

Vossloh-Schwabe - DigiLED Mono CA
VS has just launched a new brightness control module that is designed to act as a dimming device for monochromatic and white LED modules.

The DigiLED Mono CA can be used in combination with Vossloh-Schwabe’s LED modules of the 24V standard and 24V HighPower series and has an output of 5A that enables the dimming of a complete 10 metre roll of the monochromatic LEDLine Flex SMD modules with only one DigiLED Mono CA.

Due to its compact design, (a tiny 83 x 30 x 19 millimetres) it’s especially suitable for integration into luminaires. An exact price point hasn’t been confirmed but it’s expected to be very reasonable indeed.

Robe - CitySkape Xtreme
While outdoor events may be the last thing on people’s mind at this time of the year, once the scorching temperatures drop to a more comfortable 20- or 30-something degrees, indoor events will take a back stage - and Robe has just released a LED fixture they say is the most powerful on the outdoor market, with 188 high power Luxeon K2 RGBW LEDs.

The LEDs are densely populated, which contribute to the extremely bright light output. The unit is completely silent due to the convection cooling system and its IP 65 rating means it can be used for a variety of exterior installations like large buildings and stages - early users say that it lights curved and high walls particularly well. Another plus, according to Robe, is that is offers some of the best ‘true’ white light around.
