The detail behind
the light.

Photometrics, controls, emergency and warranty are documented the same way on every range, so your calculations, schedules and compliance statements rest on data you can check.

PHOTOMETRICS Ready for Relux LDT files checked against the datasheet flux and wattage and named by part code, so the right file goes straight into your calculation.
CONTROLS Control, your way Fixed output, DALI and DALI-2, DT8 tunable white, mains dimming, corridor function or Casambi wireless. Tridonic driver as standard.
EMERGENCY Emergency, built in 3hr, self-test or DALI-2 emergency, integral or remote, to suit BS 5266-1 schemes and coded the same way on every range.
WARRANTY Five years, in writing Every diVa luminaire carries a five-year warranty, stated on its datasheet.
