ECLIPSE - professional museum and art gallery light with interchangeable lenses
Eclipse sets new standards in lighting technology
The lighting of museums – and other projects with similar requirements such as those in the luxury retail segment – places the highest demands on lighting tools. The interchangeable lens units with darklight lenses not only create a magical impression with only one light point. They also offer precise, uniform light distributions and wide flexibility in the choice of beam characteristics: ranging from miniaturised lighting in confined spaces with Minirail 48V track and wall washing in picture galleries to the display of large exhibits in halls and atria. An extensive range of accessories round off the system – and Eclipse also offers innovative connectivity solutions using wireless standards such as Casambi Bluetooth and Zigbee.
Everything from accenting to wallwashing
In-house developed optics exploit the full potential of efficiency and quality of light. The lenses guide the light with maximum precision, precisely defined light beams and high illuminances onto the target surface. From crisp-edged accen-tuation to uniform wallwashing – the complete bandwidth with just one luminaire range.
" There are five spotlight sizes in the range, starting with the smallest size at 32mm in diameter, which delivers up to 375 lumens from 3.2W. The largest size at 145mm diameter delivers up to 6,468 lumens from 58.4W. All sizes of spotlight incorporate integral drivers.
The spotlights can be mounted onto three types of track adapter. The three smallest size spotlights are available with an adapter for 48V LV Minirail track. All five spotlight sizes are available with a 230V AC InTrack adapter that fits within the profile of three circuit mains track with DALI conductors to give a fully integrated appearance. The three smallest size spotlights are also available with adapters for standard three circuit track. To complete the mounting options the track adapters on the low voltage spotlights can also be mounted into 230V track with a custom-designed adapter incorporating a 48V DC transformer.
Standard LED light engines include six fixed colour temperatures with a CRI of up to 97, tuneable white and RGBW options. Four add-on filters enable the fixed LED colour temperatures to be fine-tuned on site. A wide variety of glare control accessories including snoots and barn doors are included in the range. Up to three accessories can be attached to each spotlight using the bayonet system.
Probably the most impressive aspect of the Eclipse range is the optics. Each spotlight size incorporates a light engine fitted with primary lens. The light output from the primary lens is then modified with a secondary optic, which attaches to the spotlight with a bayonet fixing designed for single-handed assembly and disassembly. Rotate clockwise to attach and anti-clockwise to remove these lenses. As you would expect, the range of secondary optics is ample; for each size there are three symmetric fixed spot beam angles, two fixed wide symmetric beam angles, two zoom options – one symmetric and the other rectangular, two elliptical distributions, a wall washer and a framing accessory with adjustable shutters. The Darklight wide lenses produce a soft edge beam without any spill light and provide good visual comfort with a 60° cut off angle.
The quality of the light output from the two samples I examined was good with even distributions, no colour over angle issues and only a few slight imperfections in the beam on a couple of the lenses. The elliptical distribution from the 35mm diameter sample produced a remarkably wide thin blade of light.
Dimming control is achieved with a very neat add-on module that plugs into the back of the spotlights. One version provides local manual dimming, the multi-dim module provides DALI, push dim and phase dimming while other modules provide Casambi or Zigbee wireless control. A combination of manual and remote dimming does not seem to be an option at the moment.
The build quality of the samples I tested was generally acceptable, although I found that the moulded lens fixing bayonet ring came loose on one of the 60mm lenses. The lenses on the 60mm sample were rather loosely held and could be pulled off quite easily without rotation. It is possible that the samples I tested were from a pre-production batch and perhaps this would not be an issue with production products.
The overall design of the spotlights was well-executed with no visible screws and the body castings include a perforated pattern that pays a small homage to the earlier Bellini design, which is a nice touch. Some of the design detailing on the mounting-bracket seemed rather idiosyncratic and did not correlate with the body casting design. Apart from these small details, the overall impression and the optical performance of the samples was excellent. Considerable effort has been taken to minimise any stray light leaks.
The Eclipse range is a major development for Erco and is likely to be very successful in its target markets of galleries, museums and premium retail brands. " review made by Arc Magazine
