9 Inch 72W Spot High Brightness Red Blue Color Overhead Tower Crane Safety Warning Light
The SLL-9072 is a 9 inch spot high brightness red or blue overhead tower crane safety warning light designed for machines that operate in low visibility conditions and require clear visual signals for operator and ground crew safety. The 72W output with CREE LEDs delivers a focused beam that cuts through fog, rain, and dust, ensuring the crane's presence is seen at long range. The die-cast aluminium housing and stainless steel bracket resist corrosion and vibration, making it suitable for continuous outdoor use on cranes and heavy machinery. The light operates on 12-48V DC, covering both 12V and 24V systems, and is rated for over 50,000 hours, reducing maintenance frequency on high-use equipment.
- Spot beam pattern with high brightness ensures visibility at long range in fog, rain, and dust
- CREE LEDs deliver 72W real power with a 50,000 hour lifespan, reducing replacement frequency
- 150 degree adjustable mounting bracket allows precise aiming for optimal warning coverage
- Die-cast aluminium housing and stainless steel bracket resist corrosion and vibration
- 12-48V DC operation supports both 12V and 24V systems, reducing SKU count for fleet operators
Where This Lamp Is Used
- Overhead warning lighting on tower cranes in ports and construction sites with high traffic
- Safety signaling on mobile cranes operating at night or in low visibility conditions
- Warning lights on engineering vehicles and excavators where visibility is critical
- Fleet-wide installation on crane fleets using mixed 12V and 24V electrical systems
- Installation on machinery in coastal or industrial zones where salt and moisture accelerate corrosion
Who It Is For
- Machinery OEMs integrating safety lights into new crane models during production
- Fleet operators maintaining large crane or heavy equipment fleets needing long-life warning lights
- Distributors supplying safety lighting to construction and port equipment dealers
- Equipment dealers fitting warning lights on used cranes and machinery for resale
- 4x4 and industrial accessory brands building private label safety light ranges
Problems It Solves
- Low brightness warning lights fail to be seen at distance in fog or rain, increasing accident risk
- Cheap plastic housings degrade under UV exposure and fail in high vibration environments
- Non-adjustable brackets make it difficult to aim lights correctly on uneven crane structures
- Short-lived LEDs require frequent replacement on cranes that operate 24/7
- Lack of 12-48V compatibility forces fleets to stock multiple part numbers for different voltage systems
Technical Features
- 72W real power with CREE LED chips delivering high brightness in a focused spot beam
- Spot beam pattern with a 1 lux reading at 150 meters for long-range visibility
- Adjustable mounting bracket with 150 degree up/down range for precise aiming
- Die-cast aluminium housing with semi-gloss black powder coating for durability
- Polycarbonate (PC) cover resistant to impact and UV degradation
- 12-48V DC input range compatible with 12V and 24V systems on cranes and heavy machinery
- Mounting bracket width of 50mm, compatible with standard crane mounting points

How It Compares With the Alternatives
| Halogen warning light of similar output | Draws 6A at 12V against roughly triple that for halogen and survives vibration that destroys filaments |
|---|---|
| Round 9 inch warning light | The square body provides a larger mounting footprint and better heat dissipation but requires a flat surface for the bracket |
| Flood beam version of the same lamp | Spot beam reaches further ahead for long-range warning while flood covers a wider area but with less reach |
| Smaller 6 inch warning light | Higher output and longer beam reach but requires more space on the crane structure |
How to Fit and Use It
- Mount on a flat surface using the bottom bracket and verify the 50mm bracket width against the crane mounting point before drilling
- Wire through a fused feed sized for 6A at 12V or 3A at 24V and keep the cable entry pointing downward
- Adjust the bracket to aim the spot beam at the required warning zone, using the 150 degree range for optimal coverage
- Clean the PC lens with water and a soft cloth only; avoid solvents that may damage the anti-UV 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 12 to 48V DC, so the same part number can be fitted to 12V and 24V vehicles and cranes.
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.
