impression S mono black

The impression S350 is a mid size LED spot fixture that sets new standards in quality of light. A new, highly advanced feature set, allows the S350 to be controlled in incredibly unique ways, and backs this up with very superb CRI rating of >90 & TLCI (Qa) rating of 90, with a very flat field. Additionally, a new 3-D dimming algorithm & near silent operation, means the S350 advances existing tech in multiple areas.

The impression S350 offers an unparalleled feature set for its size. A highly efficient optical system uses a powerful 6000 Kelvin white LED engine at its core, producing bright clarity in the projected beam. Smooth dimming using a brand new 16 bit, 3D dimming algorithm and even field distribution along with clear image projection are all standard in the S350. While maintaining a significantly brighter output than typical 700W discharge lamp sources.

With near silent operation, the S350 is suitable for every kind of venue and event that needs a powerful fixture in a small and subtle housing.

The color capability of the S350 comes from a full CMY color mixing system, supported by a fixed color wheel with correction filters.  Beam control begins with a 4 blade framing system with each blade capable of closing across the entire beam, all within a rotating gate. This is supported by a full beam rotatable and repositionable animation wheel, alongside a rotating gobo wheel with 7 positions plus open and a static gobo wheel with 10 positions plus open, and a rotating prism. Also included are 2 selectable frost filters, giving the option of both light and heavy frost effects. Beam control capabilities include motorized focus and a zoom that gives a wide range of 8° to 41°.

The S350 features GLP’s unique baseless design with full 16 bit pan and tilt movement, full range 16 bit dimming, and electronic shutter capability, all with a low weight of just 56 lbs (25.4 kg). The S350 also features an inbuilt battery for fixture setup, an auto sensing power supply, and the option to have wireless DMX control.

The impression S350 spot fixture is a class leader in all areas.
