ETC Desire Fresnel DFL7: speakers and camera whites
Define variant, beam spread and color mode before comparing stage white and skin rendition.
Model and application
This guide covers Desire Fresnel DFL7 Lustr X8. DFL5 is another size and needs its own equipment and accessory check; fos/4 Fresnel and ColorSource are different models. Use official manual 1.4.0 Rev A and check that the document and version match the unit being prepared.
For a fixed speaker, check facial shadows, reflections in eyeglasses and light on the background. For movement, evaluate the full area or multiple zones before fixture count. Photos and approximate dimensions can start the comparison.
Prepare your inquiry
- Send the date, venue, participant count, movement area and tentative duration. Photos and approximate dimensions are enough to start.
- Identify permitted mounting positions, cameras and existing lights, and what your production supplies.
- GLMedia can evaluate rental and alternatives, mounting, configuration and operation. Model, accessories, availability and scope require proposal confirmation.
Functions and connections
Set the zoom manually on the fixture before the event. For beam-width changes during the show, evaluate prepared zones or another source with documented remote zoom; confirm the variant’s optics and accessories.
Studio provides CCT, Tint and Tuning; Direct and Expanded are not interchangeable mixes. Record mode, white reference and settings before color comparisons.
Proposed preparation
- Identify DFL7, software and accessories. Have qualified personnel verify mounting and non-dimmed power under the manual.
- Define positions and shots. Set manual beam spread and aim with the subject at marks; check shadows, endpoints and background spill.
- Match personality and mode before testing controls. At agreed camera exposure, compare isolated light, skin, clothing and a neutral reference.
- Save the approved state and repeat levels and transitions. Do not change mode, correction and exposure together or reset calibration to chase a color name.
Questions and troubleshooting
Can I change beam width from the console during a presentation?
Documented zoom is manual. Include physical preparation before the event.
- Test positions and beam width with fixture and accessories secured. For different tasks, evaluate prepared zones or another source with documented remote zoom.
- GLMedia can compare options for the speaker’s movement and quote equipment, mounting, focusing, configuration or operation. This unit does not provide DMX zoom.
Why does white change between Studio, Direct and another source?
Modes and spectral reference matter; identical CCT or gel names do not prove the same skin rendition.
- Compare one source at a time with a fixed camera. Record mode, CCT, Tint, Tuning and level before saving palettes.
- The manual’s Spectral setting prioritizes spectral matching at lower intensity than Brightest. Compare both in the intended shot and at the planned exposure to choose the skin rendition and light level the production needs.
What is needed to evaluate speaker or panel lighting?
Start with date, venue, goal and a photo even when optics or drawings remain undefined.
- Add participant count, movement, approximate distances/heights, cameras and existing lights. Identify equipment-only versus preparation/operation needs.
- The proposal confirms variant, accessories, count, feasible positions and availability. Camera and coverage tests are agreed for the actual package.
Precautions
- The manual specifies indoor use. Do not transfer outdoor-model conditions or improvise protective covers.
- Qualified personnel must verify mounts, safety attachments and power for the actual unit and accessories; do not feed it from a dimmer output.
- Keep movement clear, follow ventilation and manual restrictions, and avoid direct eye exposure. Persistent errors or damage require removal from service, not field opening or recalibration.
