The FEL-S2 A is the single-colour member of the FEL-S2 Fresnel family. It pairs a 350W COB LED with a real Fresnel lens, so you get the soft-edged beam that lighting designers reach for in theatre and studio work, without the lamp changes, the heat and the power draw of a tungsten unit of similar output. Where the S2 B adds bi-colour and the S2 C adds full colour mixing, the S2 A keeps things simple: one fixed colour temperature, chosen when you order.
The tungsten look, without the lamp
The standard version runs a 3000K COB chosen to match the warm, familiar colour of tungsten lighting, which is the look most theatres still expect from a Fresnel. Colour rendering is the headline: CRI above 97 and CQS of at least 96, so skin tones and costumes read naturally to both the audience and the camera. If your rig is daylight-balanced, 4000K and 6000K versions are available to order with the same rendering figures.
Optics and zoom
The Fresnel lens gives the fixture its character: a soft-edged pool of light that blends into the surrounding wash instead of cutting a hard circle through it. The beam zooms manually from a 15-degree spot to a 55-degree flood, enough range to move the same fixture between a tight special and a general area wash during a rig check. A motorised auto-zoom version is available as an option if you want the focus under console control.
Control and dimming
Control is DMX512 with RDM, so addresses and status readback can be set remotely instead of on a ladder. The fixture runs one channel for straight dimming, or two channels for 16-bit fine dimming. Four dimming curves are selectable, and the PWM frequency runs from 1 to 20 kHz, so the output stays steady for camera work at the settings film and broadcast crews use. When no console is in the room, built-in programs run the fixture standalone. Connections are 3-pin or 5-pin XLR for DMX plus an RJ45 interface, and power enters through Seetronic connectors with genuine Neutrik available as an option.
Build and cooling
The housing is aluminium with a matte grey finish, and a fan keeps the 350W COB cool through long show days. It measures 481×324×444mm and hangs on a standard lighting stand or rigging point. The rating is IP20, so this is an indoor fixture: stage, studio, and covered venue use.
Power and data connections
Power runs in and out through the Seetronic connectors, so fixtures can be daisy-chained along the truss; specify Neutrik connectors at order if your stock prefers them. Data is on standard XLR, 3-pin or 5-pin, with the RJ45 interface alongside for installations that prefer it. Nothing here needs an external ballast or separate dimmer pack; the fixture is its own dimmer.
Où est-il utilisé ?
Theatres and opera houses use it for key light and specials where the warm Fresnel look is still the reference. Television studios put it to work as key and fill light that matches alongside other fixtures on the same camera. Concert and touring rigs take it for the output-to-power ratio, since a 350W draw is gentle on generator supplies. Film and drama sets use the soft beam for scenes shot at high frame rates, where the steady dimming matters. Houses of worship and conference halls value the simple DMX integration, and rental houses stock it as the long-life replacement for their ageing tungsten Fresnels.
Lifespan
The LED source is rated for 50,000 hours. Run twelve hours a day and that is more than eleven years before the source is a question, and there are no lamps to stock or swap in the meantime. The fan and the housing are the only service points, and both are accessible without special tools.
