Erden Brass EB2-U Uplight
Model: LS3320
Overview
The EB2 is a compact, factory-sealed inground luminaire designed for harsh exterior environments. It features a corrosion-resistant brass body, an IP68 rating, and MicroAntileach cable entry, ensuring long-term reliability in coastal, urban, or high-moisture settings without requiring drainage.
Available in vertical or 15° angled uplight options, the EB2 supports RGBW, RGBA, Static, and Tunable White output. It offers DMX/RDM control via PowerSync, enabling dynamic lighting scenes and remote management.
Optical accessories such as wall-wash lenses, hex-cell louvers, and glare shields are available to provide beam control and visual comfort. The luminaire lid is offered in brass, which develops an elegant natural patina over time, or cast 316 stainless steel, known for its superior corrosion resistance and durability in high-salinity, high-exposure environments.
The EB2 is drive-over rated and compact with a 4.7" (120 mm) diameter, delivering up to 810 lumens. It can be installed easily via direct burial, pre-installation kits, or a 4" conduit system, making it suitable for discreet yet powerful architectural or landscape lighting.

Installation Methods & Accessories
Installation Types
Pre-Installation Blockout
This method requires the LS6388 Pre-Installation Kit (ordered separately). It acts as a concrete blockout installed before the luminaire, protecting it from damage during concreting or other site works. It is used for drive-over, general use, and concrete pour applications where the luminaire is installed after site work is completed. Benefits include easy removal for servicing.
Conduit Mount
This installation allows the luminaire to be locked into a standard schedule 40, 4" (100mm) conduit (supplied by others). This protects the luminaire during site works. It is used for drive-over, general use, and concrete pour applications. Benefits include easy removal for servicing. The conduit can be procured locally.
Direct Burial
The luminaire is installed directly into soil or soft landscapes. It is used for landscaping areas and applications where depth is restricted. Benefits include simple installation and easy repositioning as landscapes evolve. It is not suitable for drive-over applications and requires pre-installation. Connection Type '82' is only available for the North American market.
Connection Types
Connection type '84'
Features Flexible Cable for connections to the branch circuit via junction box (by others) or other approved method. Available in 6.5' (2 m) length, with other lengths available upon contact with Lumascape.
Connection type '82'
Features a ½" NPT Adapter. The luminaire is factory-fitted with 6.5' (2 m) hookup wire. Ensure terminations can be made within this length. For other length options, consult Lumascape. This type is North American market only.
Round Flush Cover
Flush covers are used for installation in fine finished surfaces like granite and marble, and in some suspended applications to conceal gaps between the luminaire and the surrounding surface. They ensure static loads up to 6,614 lb (3,000 kg) are properly supported, requiring OptiClear™ or GripGlass™ for drive-over rating.
Available finishes:
- SS316: Electro Polished
- Brass: Tumbled

Trunk Topology
The Trunk Topology is recommended for Above Water Applications, detailing circuit limits for Dimmable and Color-Changing via PowerSync™.
System diagram illustrating the Trunk Topology. It shows a control signal (120 to 277 Vac) feeding a Power Supply (PSU), which then connects to a LV PowerSync Data Injector (LS6550). The Data Injector outputs Vdc + Data via a trunk cable (14 AWG / 2.5 mm²) to multiple luminaires. The diagram specifies maximum total trunk cable length (6' / 1.8m) and cable between luminaires (14 AWG / 2.5 mm²). A PowerSync™ Terminator (T) is shown at the end of the chain.
Important Notes:
- Refer to the "Transformer Compatibility Table" for the maximum number of luminaires per power supply.
- Calculations are based on 14 AWG (2.5 mm²) trunk cable and 16' (5 m) trunk cable between luminaires.
- Always observe local electrical codes for branch circuit current limitations.
- For other configurations, contact Lumascape.
