Architektur MD8LED Series is a 8” specification grade high output LED downlight capable of delivering over 16,500 lumens and designed for ceiling heights from 20 to 60 feet.
Combining energy savings, long life, low maintenance cost & controllability, it is an excellent alternative to metal halide (up to 250 watts) and quartz (up to 500 watts) fixtures. ENERGY STAR qualified. Rated for a minimum of 50,000 hours life with 70% Lumen maintenance up to 40°C (104°F) when free airflow is available around the fixture. Rated for a minimum of 60,000 hours life with 85% lumen maintenance up to 30°C (86°F) when free airflow is available around the fixture and no lens is present.

HOUSING:
18 gauge corrosion protected steel platform designed for accessibility. Pre-wired J-box with snap-on covers.
Separate power supply module serviceable and removable from above or below the ceiling. Power supply module is connected to the LED light engine using a locking plug-in connector. Approved for 8 (4 in/4 out) No. 12 AWG conductors rated for 90°C through wiring. Variable light engine mounts allow reflectors to be interchanged in the field.

LED LIGHT ENGINE:
The MD8LED uses up to 480 individual Nichia LEDs specifically mixed to provide a minimum of 80 CRI with 3 SDCM color consistency. The LED light engine is available in multiple lumen packages and color temperatures to accommodate any design requirement. The use of individual LEDs to achieve these lumen packages enables optimal thermal management while creating a visually pleasing diffuse appearance in the ceiling. The LED light engine is coupled to a passive heat sink utilizing innovative heat pipe technology, and is protected with a self resetting thermal protector.

LED DRIVER:
Each string of 120 LEDs is powered by a single 40 watt, constant current LED driver (up for 4 drivers per fixture). The driver is UL8750 and Class 2 compliant. Lutron Series A drivers lso available

DIMMING:
Standard 0-10v dimming provides flicker-free dimming to 10%. For sizing of the circuit control, the dimming circuit may require up to 1.2mA of sink current. See list of compatible dimmers below in the Dimming Compatibility Table.
Lutron EcoSystem, or 0-10V dimming available to 1%, and DMX with RDM (remote device management) dimming to less than 0.1%.

INSTALLATION:
Universal adjustable mounting brackets accommodate 1.5” or ¾” lathing channel or ½” EMT (by others) or Prescolite B24 or B6 bar hangers.

CERTIFICATIONS:
CSA certified to US and Canadian safety standards. Suitable for damp locations, or wet locations with a lens. Non-IC rated and approved for 90ºC, 4IN/4OUT, through branch wiring.
