ELVARNIXO Continuous — what you see is what you shoot
The Cursa is what-you-see-is-what-you-shoot: a point-source COB with serial-measured colour, flicker-free drive past any shutter you own, and thermals that hold minute ninety at minute-one brightness.
An LED fixture is a colour instrument wearing a lamp costume. Ours start with binned emitters mixed by spectrometer, not by eye — CRI, TLCI and SSI stated in the specification — and hold their point through hours of tungsten-to-daylight travel. Drivers are flicker-free past 25,000 fps shutter equivalents, dimming curves are broadcast-smooth to a tenth of a percent, and thermals are engineered so output at minute ninety equals output at minute one.
Design & Craft
- Output at minute ninety equals output at minute one — thermals engineered
- Point-source COB for crisp shadows and honest modifier behaviour
- DMX/RDM, wireless and app control with clear priority rules
- Dimming curves smooth to 0.1% with four selectable laws
- CCT travel 2700–6500 K holding tint within measurement
- Flicker-free past 25,000 fps shutter equivalents at every dimming level

Care
Dust is the enemy of thermals: clear intakes monthly and keep diffusion domes clean — output and colour depend on it. Update firmware when prompted; calibration data rides along. Never force a yoke bolt: torque figures are printed at the knuckle.
Questions, Answered
Do fixtures match each other?
Units of the same model are factory-calibrated to the manufacturer's colour specification, so a fleet reads as one light. The stated tolerances are in each listing.
How loud is the fan?
Noise figures at each fan mode are in the specification, stated at one metre. Hush modes hold output within the stated derating.
