Building on the superb MSL™ (Multi-Spectral Light) colour concept, and innovative TE™ technology, our T11 Fresnel™ maintains the exceptional colour finesse of the phenomenally successful T series. With a fast, interchangeable front lens system, the T11 Fresnel™ offers absolute, cost-effective flexibility while delivering superb optical quality.

With the MSL-TE™ 350W LED Engine generating over 12.000 lm from the Fresnel fixture and all the advantages of cost, exchange or replacement, this LED technology provides identical colour characteristics, responses, and control of T series luminaires, giving absolute colour consistency across your Robe lighting installation.

High-definition optics deliver the classically soft Fresnel style beam, with a wide-ranging 5-60° zoom range.

A virtually controlled CCT range of 2.700K to 8.000K, calibrated whites, and tungsten emulation gives precise control, while we ensure skin tones are perfectly rendered due to T11’s high TLCI and TM30-18 ratings and exceptional CRI of 95+.

Our innovative manual shuttering system, functioning as an internal barn door, is both accurate and easy to use. Integral to the fixture is a manual 5° MagFrost™ for instant softening, with an optional 1° frost available.

The unobtrusive T11 Fresnel is specifically designed to operate in any noise-sensitive environment, with TV studio use enhanced via Cpulse™ flicker-free software and a dedicated plus and minus green channel control.

Utilizing the rapid-change front lens system, the T11 Fresnel™ quickly transforms into a Profile or PC fixture for total luminaire flexibility without the cost of separate generic purchases.

T11 The three into one generic solution!
