The FEL-S1 B is a 200W bi-color LED Fresnel built for film, TV, photography and broadcast sets that are replacing tungsten spotlights. It gives a soft-edged Fresnel beam with top-tier color quality at roughly one-fifth the power draw of a 1kW open-face, and with far less forward heat. That matters for talent comfort and for the air-conditioning bill.
What is under the hood
At the heart is a 2-in-1 COB LED: one chip running warm, one running cool, blended through the Fresnel lens. The 2700K to 6400K range matches tungsten and daylight without gels. Three quick-select preset color temperatures cover the common cases; in between, the CCT is fully variable. Color rendering is CRI greater than 97 and CQS 96 or above across the whole range. Skin tones and costume colors hold up to camera without heavy post-production correction.
Beam control and dimming
The lens is a Fresnel with a manual zoom from a 10° spot to a 50° flood, set from the rear of the unit. A motorized auto-zoom controlled by DMX is available as a factory option. Dimming runs through 1 to 20 kHz PWM with 16-bit resolution; four selectable dimming curves let you match the response to what you are shooting. The result is flicker-free operation even at very high frame rates.
Control and connectivity
The control layout is standard DMX512 with RDM for addressing and diagnostics. Channel options are 2 (CCT and dimmer), 3 (adds strobe) or 6. Standalone programs for TV flicker, paparazzi, lightning and candle effects are built in, so a unit can run effects without a desk. Manual control is available on the rear panel. Data comes in through 3- or 5-pin XLR or RJ45 Ethernet. Power is a Seetronic powerCON-compatible in/out on the back; a true1 Neutrik option is available for installations that require it. Daisy-chaining across a row of fixtures is straightforward.
Structure and cooling
The body is precision-machined aluminum in a matte grey finish. The heat sink is sized for the 200W light source, and a temperature-regulated fan keeps the LED at its rated temperature. Measured fan noise stays at or below 32 dB at one meter, which is quiet enough for classical theater and for picking up dialogue close to the light. The unit is rated IP20: a stage and studio fixture, not a washdown or outdoor light. Dimensions are 481 × 324 × 444 mm and the weight is about 9.5 kg, so it rigs on a junior stand or a pipe grid without special rigging. LED life is 50,000 hours.
Where it earns its keep
Key, fill and back light in multi-camera broadcast studios that need matching color across rigs. Specials and front light in professional theater, where the quiet fan and cool beam let the light sit close to performers. Narrative film sets that want a traditional Fresnel look without a hot tungsten unit on the stage floor. LED volume and virtual production stages, where a CRI above 97 and an accurate CCT matter for matching the LED wall. And in rental houses, where a 50,000-hour LED source and fan-only maintenance beat the lamp-change cycle of the tungsten inventory it replaces.
Certifications and warranty
The FEL-S1 B ships with SAA, CE and RoHS certifications. The SAA mark covers Australian and New Zealand market requirements. The warranty period is three to five years depending on region and distributor terms.
Optional upgrades and accessories
A motorized auto-zoom, addressable over DMX, replaces the manual rear zoom wheel and covers shows where the beam size changes between scenes without a lane op. A true1 Neutrik power input replaces the Seetronic-compatible socket for installations that spec the original. Standard 8-leaf barn doors and gel frames are not included; most rental parks already stock them, but for a single unit pulled off a shelf, budget a set with the first order so the rig is complete on arrival.
