5 Inch 27W Utility High Intensity LED Work Light E-Mark Approved
The SLL-5027-27 is a 5 inch utility high intensity LED work light designed for machines that operate in extreme conditions across agriculture, forestry, mining, roadwork and construction. It delivers 2200 effective lumens from nine 3W CREE LEDs, maintaining visibility in dust, rain and vibration. The E-Mark approval ensures compliance with European vehicle lighting standards, which is required for machines used on public roads. The die-cast aluminium housing with UV-resistant polyester coating resists corrosion and impact, while IP68 sealing prevents water and dust ingress during pressure washing or prolonged exposure.
- 2200 effective lumens from nine 3W CREE LEDs provide broad, even illumination across the work zone
- E-Mark approval allows use on public roads in Europe without electrical interference issues
- IP68 sealing and a durable polycarbonate lens prevent water ingress and fogging after repeated wash cycles
- 9 to 32V DC operation supports both 12V and 24V vehicle systems, reducing SKU count
- Overvoltage and overheat protection extend service life in unstable electrical environments
Where This Lamp Is Used
- Front and side lighting on agricultural tractors and harvesters working at dusk or in low light
- Cab and boom lighting on excavators and loaders operating in dusty or wet conditions
- Auxiliary lighting on mining support vehicles exposed to vibration and temperature extremes
- Roadwork vehicle lighting where E-Mark compliance is required for public road use
- Construction site lighting on cranes and engineering vehicles that are washed daily
Who It Is For
- Distributors of vehicle lighting who need one part number for both 12V and 24V fleets
- Machinery OEMs fitting work lights on production lines and requiring E-Mark compliance
- Fleet operators replacing halogen lamps that fail under vibration or in extreme temperatures
- 4x4 and industrial accessory brands building a private label utility light range
- Equipment dealers fitting lights on machines used in agriculture, mining and roadwork
Problems It Solves
- Halogen work lights fail quickly under vibration and draw excessive current from vehicle alternators
- Cheap sealed lamps let water in through the cable entry and fog up after a few wash cycles
- Uncertified auxiliary lighting can be rejected during vehicle inspection on public roads in Europe
- Narrow spot beams leave the near working area dark, while wide flood beams lack reach
- Painted mild steel brackets corrode within months on machines exposed to salt or moisture
Technical Features
- Nine 3W CREE LEDs with a total real power draw of 27W and a maximum rating of 30W
- Flood or spot beam options available to match the work area or reach requirement
- Semi-gloss black durable UV polyester powder coating over the full housing and bracket
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- Overvoltage and overheat protection circuits to prevent damage in unstable electrical environments
- Operating window of -40 to +85 degrees Celsius, suitable for extreme cold and hot climates

LED board assembly with CREE emitters
Lens bonding and gasket sealing
Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing verified against the IP68 rating before shipment
- Vibration testing on a vibration test machine to reproduce machine mounted service
- Salt spray corrosion testing on housing coating and stainless bracket
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius window
Customisation Options
- Deutsch DT connector instead of the standard 40cm bare wire lead
- Spot beam optics in place of the flood pattern
- Private label logo on the housing and printed carton
- Alternative cable length for a specific machine harness
- Mixed cartons combining this lamp with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Round 5 inch work lamp | The square body puts more LED area behind the same mounting footprint but needs a flat surface for the bottom bracket |
|---|---|
| Spot beam version of the same lamp | Flood covers the near working area evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 6 inch work lamp | Lower output but fits guard rails and cab pillars where a 6 inch body will not clear |
How to Fit and Use It
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Aim the flood beam at the working area close to the machine and use a spot lamp separately for distance
- Clean the PC lens with water and a soft cloth only, since solvents will haze the anti-reflective 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 road going machines
Yes. The lamp carries E-Mark approval for electromagnetic compatibility and is CE and RoHS compliant.
