How to Estimate Delivered Lumens in Emergency Mode: Delivered Lumens = 1.25 x P x LPW. P = Output power of emergency driver (10W for EM option). LPW = Lumen per watt rating of the luminaire.

Specifications

Construction

Shallow, less than 1.2", solid ring with white finish. Non-conductive construction allows for light shower applications.

Optics

Light guide technology combined with diffusing lens conceals the LEDs from direct view and provides uniform lens luminance.

LED Light Engine

LEDs mounted directly to heatsink designed to provide superior thermal management and ensure long life. Selectable CCT with steps at 27K, 30K, 35K, 40K, 50K. LEDs binned for 4-step MacAdam ellipse color consistency. 90 CRI minimum.

LED Driver

Choice of dedicated 120 volt (120) driver or universal voltage (MVOLT) driver that accommodates input voltages from 120-277 volts AC at 50/60Hz. Power factor > 0.9 at 120V input. 120 volt driver is dimmable with the use of most incandescent, magnetic low voltage and electronic low voltage wall box dimmers. Universal voltage driver is dimmable with the use of most 0-10V wall box dimmers. For a list of compatible dimmers, see JUNOSLIMFORM-DIM.

Emergency Battery Option

Battery factory assembled to fixture with integral test switch. Drives LEDs for 90 minutes to meet Life Safety Code (NFPA-LSC), National Electrical Code (NEC), and UL requirements. Title 20 certified battery pack. EBX option provides back box without battery for consistent look when used in same space as fixtures with EM emergency option. Damp location only with emergency option.

Installation

Junction Box Mounting

Fixture provided with leads for direct wire connection in j-box. Installs directly to industry standard junction boxes. Compatible boxes include 4" metal or plastic octagonal standard and IC1JB junction box housing (3 1/2" junction box screw-hole spacing required for installation). Minimum 1 3/4" depth and 3" minimum diameter of clearance space in junction box required for installation of 11" and 13" fixtures. Quick mount bracket provides fast installation of fully assembled fixture to junction box. Suitable for ceiling mount. Suitable for use within closet storage spaces when installed per NEC requirements. Junction box sizes vary - Verify compatibility with fixture prior to installation.
