Light Efficient Design LBI Linear LED Lights | FlexWatt & FlexColorWhat is a Light Efficient Design LBI LED light?The Light Efficient Design LBI is a linkable linear LED light bar with an internal driver. FlexWatt and FlexColor technology lets installers select from three wattages and three color temperatures, providing as many as 9 lighting configurations from one product. ⚙️ 1. Choose the Length, Wattage & Color TemperatureStart with the fixture length. Then set the light output and CCT at installation instead of stocking separate fixtures for every wattage and color temperature.
2-Foot LBI
Approx. fixture length: 19.3"
FlexWatt:
6W • 9W • 12W
Lumens @ 3500K:
706 • 1,063 • 1,419
3-Foot LBI

4-Foot LBI
Approx. fixture length: 43.3"
FlexWatt:
10W • 15W • 25W
Lumens @ 3500K:
1,344 • 2,255 • 3,166 🎨 Standard FlexColor
3500K Neutral
4000K Natural

9 configurations from one selectable light
3 wattages × 3 color temperatures = 9 possible configurations. This reduces the need to predict the final light level and CCT before the fixture reaches the jobsite.
🏭 2. Match the LBI to the InstallationThe LBI platform can be configured for retrofit work, standalone linear lighting, or linked installations. Choose mounting accessories according to the fixture and application.
🏢
TroffersRetrofit existing fluorescent-style troffers using LBI bars and linking cables where multiple bars are required.
🏭
High & Low BaysUse blade clips, linking cables and available suspension hardware to build LED high-bay or low-bay configurations.
💧
Vapor-Tight FixturesUse the compact internal-driver light bar as the LED light source inside compatible vapor-tight housings.
↔️
Continuous RunsJoin bars with seamless or spacer connectors for long architectural, commercial or industrial linear runs.
📐
Cove & DisplayAim the light using the 45° mounting bracket for indirect cove lighting, displays and architectural illumination.
🚶
Stairwells & PassagewaysCombine selectable output with occupancy and daylight controls where lighting demand changes throughout the day.
✓ Retrofit + fixture flexibility:
The LBI is listed as both a UL 1598 Class A fixture and a UL 1598C retrofit kit, making the platform useful for both new fixture designs and LED upgrade projects.
🔌 3. Plan Wiring, Linking, & ControlsLBI light bars can operate individually or as linked systems. Pass-through power and control connections simplify multi-bar installations. 
🔗 Link Multiple BarsConnect bars end-to-end or use linking cables when spacing is required between light bars. 📉 0-10V DimmingPass-through 0-10V control allows connected LBI light bars to be dimmed together as a group. ⚡ 12V Auxiliary PowerThe auxiliary 12V output supports compatible inline occupancy and network control accessories. Maximum End-to-End Linking Quantity
Important: These quantities apply to end-to-end linking configuration using the LBI junction box. Linking cables reduce allowable quantities. At 120VAC, it is recommended that there is a maximum of 24 units when linking cables are used.
Smart Control Options
👁 Microwave Occupancy
OC2/OC3 controls provide high/low occupancy operation with daylight harvesting.
🚶 PIR Occupancy
An inline passive infrared option provides occupancy sensing with compatible daylight control functions.
📱 Bluetooth Mesh
Silvair-compatible network nodes support wireless grouping, commissioning and lighting control.
☀️ Daylight Harvesting
Compatible sensors can reduce artificial lighting when adequate natural light is available. 🧰 4. LBI Mounting & Installation AccessoriesUse the accessory system to adapt the same LBI light bar platform to fixture retrofits, suspended installations, continuous runs and architectural lighting. 📦 5. What Comes With an LBI Light Bar?Each LBI linear transformer LED light includes the core components needed to prepare the bar for common fixture installations.
✓ Power and control cable for bar input
✓ Power and control pigtail cable
✓ 2 surface-mount magnetic clips
✓ 4 × 1/4" hex screws
✓ Service disconnect
✓ Flex setting cover
✓ Connection wires (between service disconnect & latch connector)
✓ 3 wire nuts for low-voltage connections
