BK Series 20W–180W Integrated Solar LED Street Lighting for Road Projects
Road-lighting projects should be evaluated by actual light output—not nominal wattage alone. The BK Series covers 20W to 180W, matching the selected LED configuration with a corresponding monocrystalline solar panel, LiFePO₄ battery and MPPT controller. Available models deliver approximately 3,500 to 33,000 lumens, using 48W to 432W solar panels and 240Wh to 2,160Wh battery storage for recommended mounting heights of 5 to 15 meters.
The all-in-one die-cast aluminum housing combines the LED module, solar panel, battery, controller and sensor functions in a single IP66/IK09 unit. Automatic ON/OFF, time-dimming and motion-sensor programs support residential streets, municipal roads, parking lots, industrial areas and other off-grid lighting projects.
Depending on the selected model, local solar conditions and confirmed operating program, the system can provide 12 to 15 hours of nighttime lighting and be designed for 5 to 7 cloudy or rainy days. IES files, DIALux simulations and project-specific configurations are available to help EPC contractors, municipal authorities and commercial developers evaluate illuminance, uniformity and pole layout before procurement or tender submission.

BK Series 20W–180W All-in-One Solar LED Street Light | Product Overview Video
Integrated Solar LED Street Lighting BK Series 20W–180W Project & Application Cases
The BK Series gives project teams nine options from 20W to 180W for pathways, residential streets, rural roads, municipal roads, parking areas and industrial sites. This range is useful when one project includes several road widths or pole heights, but wattage should remain a preliminary selection rather than the final basis for lighting design.
The solar panel, LiFePO₄ battery, LED module, MPPT controller and lighting controls are built into one luminaire. A separate battery box, underground power cable and utility-grid connection are not required. This is particularly practical for new infrastructure, road extensions and replacement projects where trenching or grid expansion would add extra site work.
For a related municipal example using the same all-in-one installation approach, review the All-in-One Solar Street Light Deployment in Spain. That completed project used FX80W lights on 7 m poles, so it is included as an all-in-one technology reference rather than a BK Series deployment.
BK Series lights have been supplied for government, contractor and EPC projects in Saudi Arabia, Indonesia and multiple African markets. Projects in these regions may involve high temperatures, strong solar radiation, tropical rainfall or limited grid availability. The selected battery, solar panel, control schedule and mounting arrangement should therefore be matched to the actual site conditions.
Typical Project Configuration Reference
| LED Power | Recommended Pole Height | Preliminary Pole Spacing | Typical Applications |
|---|---|---|---|
| 20W | 5–6 m | 15–20 m | Pathways, communities and small residential roads |
| 30W | 7–8 m | 25–30 m | Residential streets and local roads |
| 40W | 8–9 m | 30–35 m | Residential and rural roads |
| 60W | 9–10 m | 30–35 m | Rural and secondary roads |
| 80W | 10–11 m | 30–35 m | Municipal roads and parking areas |
| 100W | 10–12 m | 30–40 m | Municipal roads and industrial parks |
| 120W | 11–13 m | 30–40 m | Main roads and infrastructure projects |
| 150W | 12–15 m | 35–45 m | Wider roads and large infrastructure projects |
| 180W | 13–15 m | 45–50 m | Main roads and high-output lighting projects |
Final Configuration
These figures are screening references, not fixed design limits. Before the order is approved, the selected model should be checked with the corresponding IES data and a DIALux simulation based on the actual road width, pole layout, target illuminance and uniformity.
Local solar conditions, nightly operating hours, dimming schedule and cloudy-day backup target are then used to confirm the solar panel, LiFePO₄ battery and controller program for the project.
Integrated Solar LED Street Lighting BK Series 20W–180W Production Process
BK Series orders are produced against the approved specifications and Bill of Materials. Since the range includes nine models from 20W to 180W, component identity, electrical compatibility and controller settings are checked at defined stages to reduce mix-ups in bulk and mixed-model orders.
Component Inspection & Matching
Before assembly, solar panels, LiFePO₄ batteries, LED modules, MPPT controllers, sensors, aluminum housings and mounting parts are checked against the approved BOM. Model references, battery voltage, component dimensions, connectors and electrical compatibility are verified before the parts move to assembly.
Integrated Assembly
The LED module, battery, MPPT controller, PIR sensor and wiring are secured in their fixed positions inside the die-cast aluminum housing. Cable routing, insulation, screw tightening, heat-transfer contact and sealing points are checked during assembly. Any issue found at this stage is corrected before programming and functional testing.
Controller Programming & Functional Setup
Automatic ON/OFF, time-dimming and motion-sensor settings are programmed according to the confirmed order. The operating schedule is matched to the required lighting hours, full-brightness periods and battery backup target. Motion-sensor response is checked on configurations using this function.
100% Finished-Light Functional Check
Every completed BK light is checked for solar charging, battery discharge, LED operation, automatic light control, PIR response and programmed dimming. The current BK process also includes a 48-hour aging test and sealing inspection according to the applicable inspection plan.
Before packing, the model, wattage, lighting program, labels and mounting accessories are compared with the production order. This final check helps prevent the correct light from being packed with the wrong program or installation parts.
Integrated Solar LED Street Lighting BK Series 20W–180W Overview & Details
The BK Series covers 20W to 180W for residential streets, municipal roads, parking areas, industrial parks and other off-grid lighting projects. The LED module, monocrystalline solar panel, LiFePO₄ battery, MPPT controller and lighting controls are housed in one luminaire, so there is no separate battery box and fewer external connections are needed on the pole.
LED Chips and Optical Design
Bridgelux, Philips or Osram LEDs can be specified to match the approved project requirements. Color temperatures are available from 2700K to 6500K, with CRI above 80. LED quantity, power configuration and optical lenses vary across the range.
Wattage alone does not confirm whether a road will receive the required light level or uniformity. Available IES data for the selected configuration can be used in a DIALux simulation with the actual road width, pole height, spacing and target illuminance before the layout is approved.
Solar Panel, Battery and Controller
The solar panel, battery and controller work as one energy system. Their configuration should reflect the required light output, nightly operating hours, local solar conditions and cloudy-day reserve—not simply the LED wattage.
Automatic ON/OFF, time-dimming and motion-sensor programs can be set for the agreed operating schedule. Since that schedule directly affects nightly energy use, full-brightness periods and dimming stages should be confirmed before production.
Aluminum Housing and Internal Components
The die-cast aluminum housing supports heat dissipation and carries IP66 ingress protection and IK09 impact protection. Inside, the LED module, battery, controller, sensor and wiring are held in separate fixed positions. This limits movement and allows qualified technicians to inspect or replace a key component without replacing the complete luminaire.
Mounting Bracket and Support Arms
The mounting bracket fits Φ50–76 mm pole interfaces and supports pole-top or side-arm installation. Its adjustable angle helps align the solar panel and roadway light distribution with the site layout.
Support arms, brackets and connecting accessories can be selected for the confirmed pole structure and installation direction. The pole interface and connection drawing should be checked before the mounting arrangement is released for production.
Integrated Solar LED Street Lighting BK Series 20W–180W Packaging & Delivery
Packing an integrated solar street light involves more than protecting the outer housing. The solar panel surface, optical lens, mounting interface and model-specific accessories all need suitable protection, especially when an order includes several BK wattages for different road sections.
Protection for Long-Distance Transport
Export packing for the BK Series uses an anti-scratch bag, model-matched EPE foam and a reinforced outer carton. Protection is concentrated around the solar panel, optical lens, aluminum housing and Φ50–76 mm mounting interface to reduce the risk of scratching, impact and compression during handling and long-distance transportation.
Mixed-Model Orders and Accessory Control
For orders containing different models from 20 W to 180 W, the model and wattage are marked on the corresponding cartons. Mounting brackets, support arms, bolts and other accessories are grouped according to the confirmed light configuration, helping warehouse and installation teams identify the correct parts without repeatedly opening cartons.
Pallets, wooden cases and moisture-resistant protection are available for LCL shipments and project orders when required. The final packing method is confirmed according to the model combination, order quantity, transportation method and destination.
Because the BK light contains a LiFePO₄ battery, the applicable packaging, labels and transportation documents are checked for the selected route and carrier before shipment.
Production and Shipment Planning
Order confirmation → Production → Inspection → Packing → Shipment
Sample orders: approximately 3–7 working days to prepare for shipment.
Standard bulk orders: approximately 15–22 working days, subject to the confirmed quantity and production schedule.
Project-specific orders: confirmed after the model combination, controller settings, accessories and order quantity are finalized.
These periods are production planning references. They do not include sea transit, customs clearance, port handling or inland delivery.
Estimated Port-to-Port Sea Transit
| Destination Region | Planning Reference |
|---|---|
| Southeast Asia | Approximately 5–15 days |
| Middle East | Approximately 15–30 days |
| East Africa | Approximately 25–35 days |
| West Africa | Approximately 30–45 days |
The sea-transit ranges are port-to-port estimates after vessel departure. The final schedule depends on the departure and destination ports, route, vessel availability, carrier arrangement and actual shipment conditions.
FAQ of Integrated Solar LED Street Lighting BK Series 20W–180W
Start with the road, not the wattage label. Provide the road width and lane count, pole positions, mounting height, spacing, target illuminance and uniformity, and any applicable lighting standard.
The project location and operating plan are just as important: solar conditions during the lowest-sun season, nightly operating hours, full-brightness period, dimming or sensor requirements, and cloudy-day backup. These inputs allow the LED output, 48–432 W solar-panel range and 240–2,160 Wh battery range to be matched as one system. The published 20–180 W model table is a screening guide; final selection should be checked with the correct BK IES file and actual road geometry.
The published BK target is 12–15 hours of nighttime operation and 5–7 cloudy or rainy days, but this does not mean full rated power for 12–15 hours on seven consecutive nights. The result depends on the selected model, available solar input and confirmed operating program.
Check these three values together:
- Nominal battery energy: 240–2,160 Wh across the BK range
- Solar panel power: 48–432 W according to the model
- Actual nightly consumption under the time-dimming or motion-sensor program
Nightly demand is the sum of the LED power used in each programmed stage multiplied by the hours in that stage. Backup is then checked against usable battery energy, system losses and reserve, while the panel must recover the consumed energy after normal sunlight returns.
A shorter 3–5-day reserve may be considered where sunshine is stable and cloudy periods are brief. Sites with monsoon weather, persistent fog or long winter cloud cover should be planned around the full 5–7-day target and the lowest-sun season.
Motion-sensor control is useful for pathways, parking areas and low-traffic residential streets, where activity becomes irregular later at night. It helps reserve battery energy during quiet periods and respond when movement is detected.
Fixed time dimming is easier to plan for municipal roads that need predictable light levels. The BK program should therefore be selected from traffic patterns, required full-brightness hours and the cloudy-day backup target. Exact percentages and timings are confirmed before production.
Yes. The BK internal layout keeps the battery, controller, LED module and sensor in separate fixed positions, allowing a qualified technician to replace the battery without discarding serviceable parts of the fixture.
Reduced runtime does not always mean the battery has failed. Check panel shading or soiling, controller settings and connections first. If replacement is required, match the voltage, nominal Wh, dimensions and connections to the approved configuration. This prevents charging mismatch and helps reduce lifecycle cost.
Often yes, but both the mechanical fit and the lighting layout should be confirmed before ordering. The BK mounting interface supports Φ50–76 mm pole connections, with pole-top or side-arm installation.
Check:
- Pole or arm outer diameter and connection type
- Mounting direction and arm angle
- Pole condition and local wind-load requirements
- Existing height, spacing, road width and required light distribution
A bracket may fit the pole while the existing layout still produces poor uniformity. Mechanical compatibility alone does not confirm that the lighting design will work.
The BK Series can be configured around the project specification rather than submitted as one generic fixture. Depending on the order and available manufacturing options, LED power and output within the published 20–180 W range, 2700–6500 K color temperature, LED brand, matched solar panel and LiFePO₄ battery capacity, controller schedule, mounting arrangement, labels and logo can be confirmed before production. After the BOQ, road layout, operating hours and backup target are reviewed, the agreed components, controller settings and mounting details are recorded in the approved order documents and BOM, providing a clear basis for technical submission, inspection and delivery.
