120W High Power Worklight
The SLL-9120 is a 120W high power worklight designed for heavy-duty environments where consistent, reliable illumination is critical during night operations or in low-visibility conditions. Twenty 5W CREE LEDs deliver 8,000 effective lumens, providing broad coverage across construction sites, mining zones, forestry operations, and roadwork areas. The die-cast aluminium housing with IP68 sealing and durable UV polyester powder coating ensures long-term performance under extreme vibration, dust, and water exposure. Built for 9–32V DC systems, it operates reliably on both 12V and 24V vehicles and machinery without requiring different part numbers.
- 20 x 5W CREE LEDs deliver 8,000 effective lumens for wide-area visibility in mining, construction, and forestry
- IP68 sealing and a die-cast aluminium housing resist water, dust, and vibration in harsh outdoor conditions
- 9–32V DC input range allows one part number to serve both 12V and 24V fleets, reducing SKU complexity
- Overvoltage and overheat protection prevent damage from electrical spikes and prolonged high-temperature operation
- 50,000-hour lifespan reduces maintenance frequency and replacement costs on remote or hard-to-access machines
Where This Lamp Is Used
- Front and side lighting on excavators and loaders operating at night in mining and construction zones
- Auxiliary lighting on forestry machinery where vibration and dust degrade standard lamps
- Work area illumination on roadwork vehicles and utility trucks during overnight maintenance shifts
- Cab and deck lighting on engineering vehicles used in remote or off-grid locations
- Lighting for forklifts and material handling equipment in large warehouses with poor ambient lighting
Who It Is For
- Machinery OEMs integrating high-power worklights into new vehicle builds with consistent electrical and mounting specs
- Distributors sourcing one high-output lamp for multiple applications across construction, mining, and forestry
- Fleet operators replacing halogen or low-lumen LED lamps that fail under vibration or in extreme temperatures
- 4x4 accessory brands building a rugged lighting range for off-road and industrial use
- Equipment dealers fitting worklights on used or rebuilt machines where reliability and long life are essential
Problems It Solves
- Halogen or low-lumen LED worklights burn out quickly under vibration and fail to illuminate large work zones
- Standard sealed lamps allow water ingress through cable glands during pressure washing or rain exposure
- Narrow beam lamps leave edges of the machine dark, increasing the risk of accidents in tight spaces
- Lamps with narrow voltage ranges require separate SKUs for 12V and 24V systems, increasing inventory complexity
- Painted metal housings fade and chip under UV exposure, reducing both appearance and corrosion resistance
Technical Features
- 8,000 effective lumens output with optional flood or spot beam patterns for different use cases
- Flood beam spreads light evenly across nearby work areas; spot beam extends reach for distant visibility
- Die-cast aluminium housing with semi-gloss black UV polyester powder coating for corrosion resistance
- Anti-scratch polycarbonate lens with UV stabilisation to prevent yellowing and degradation
- Overvoltage protection circuit prevents damage from voltage spikes in vehicle electrical systems
- Overheat protection shuts down the lamp if internal temperature exceeds safe operating limits
- Operating temperature range of -40 to +85 degrees Celsius for use in extreme climates
- 9–32V DC input supports both 12V and 24V vehicle systems without performance loss

- Alternative bracket design for non-standard mounting surfaces
How It Compares With the Alternatives
| Standard 50W LED worklight | Delivers 8,000 effective lumens vs. 3,000–5,000 lumens and handles higher voltage ranges |
|---|---|
| Round 120W worklight | Square body allows more LED area in same footprint but requires flat mounting surface |
| Low-cost 120W LED lamp | Lacks overvoltage and overheat protection, and uses cheaper materials that degrade faster |
How to Fit and Use It
- Select flood beam for near-area work or spot beam for long-distance visibility based on task
- Avoid direct sunlight on the lens for extended periods to preserve UV resistance
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that degrade the anti-scratch coating
Questions About This Model
Can I order a sample before placing a bulk order
Yes. Sample orders are welcome and mixed samples of different models in one shipment are accepted.
What is the lead time
Sample orders normally take around 3 to 7 working days. Bulk lead time depends on the model and the quantity ordered.
Do you have a minimum order quantity
There is an MOQ for standard orders, but smaller orders are also accepted, which suits distributors testing a new model.
How is the lamp shipped
Samples usually go by DHL, UPS, FedEx or TNT in around 4 to 7 days. Bulk orders ship by air in about 7 to 15 days or by sea in about 15 to 30 days.
Will this lamp work on both 12V and 24V machines
Yes. The operating range is 9 to 32V DC, so the same part number can be fitted to 12V and 24V vehicles.
Can you supply the lamp with our own brand
Yes. OEM and ODM service is available, including a private label logo on the housing and printed cartons.
Is it approved for use on public road vehicles
