Open Area and Escape Route Downlights (LDE3 Range)

Where projects require the advantages of low energy/long life LEDs packaged in standard downlight products for plasterboard ceilings and ceiling tiles the LDE3 range is the ideal choice.

The LDE3 downlights (silver or white thermally conductive plastic) are installed using spring clips into a 45mm diameter cut-out. The LDE3 range offers four distribution types.

LDE3/HL (HIGH LEVEL-HL)
The LDE3/HL downlight offers a narrow angle beam ideal for illumination of escapes and open areas from very high mounting hights e.g. above 5m. At 700mA the LDE3/HL can provide illuminance of 10.76 Lux from a mounting height of 11m (typical requirement for areas having to meet USA 1foot candle level).
Note: Emergency lighting kit LDCK700HL is ideal for 700mA operation.

LDE3/105 (MEDIUM BEAM)
The LDE3/105 downlight offers a medium beam (105 degree) lens configuration ideal for illumination of open areas with mounting heights typically 5 to 10m.

LDE3/WIDE (WIDE BEAM)
The LDE3/WIDE downlight offers a wide beam (160 degree) lens configuration ideal for illumination of open areas with mounting heights typically 2 to 5m.

LDE3/C (‘CORRIDOR’ BEAM)
The LDE3/C downlight offers a dissymmetric lens providing a narrow beam across the width of a corridor and extremely wide (batwing) distribution along the length of the corridor.

The LDE3 downlights may be powered from constant current drivers at 350mA, 500mA or 700mA in emergency mode as required to produce the desired lumen output to suit the application. The highest efficiency is achieved at 350mA (typically 135lm/W).

NB: The most popular ‘standard’ emergency driver pack is the LDCK330/40.
This comprises a onepiece housing for the emergency drive and high temperature NiCd battery and easily passes through the cutout required to mount the LDE3.

Description

The LDE3/C downlight offers a dissymmetric lens providing a narrow beam across the width of a corridor and extremely wide (batwing) distribution along the length of the corridor.

NB: For emergency lighting applications (inc. Self-Test/DALI projects) all LDE3 downlights offer a /RG version which incorporates a 1mm green/red bi-colour indicator.
