The Ledson Alfa21 Gen2 Curved is a powerful 21-inch curved LED light bar featuring a Driving Beam pattern and Powerboost, allowing you to choose between E-approved operation and a higher-output mode with significantly increased range.
In E-approved mode according to ECE R112, the light reaches 1 lux at 463 metres. With Powerboost activated, the range increases to 1 lux at 733 metres. Powerboost mode is not E-approved.
The curved design follows the contours of the vehicle for a more integrated appearance while delivering powerful auxiliary lighting for driving in the dark.
The Alfa21 Gen2 Curved uses computer-designed Driving Beam reflectors to produce an even and well-balanced light pattern. The beam has characteristics similar to a Combo Beam but is designed to comply with applicable regulations when used in E-approved mode.
The light pattern enhances and complements the vehicle's existing high beams, providing improved visibility both ahead of the vehicle and across the road.
A colour temperature of 5000K provides a clear, neutral white light.
The Alfa21 Gen2 Curved offers two output modes:
• E-approved mode: 1 lux at 463 metres
• Powerboost: 1 lux at 733 metres
Powerboost is activated by removing the fuse located by the DTP/ATP connector. This higher-output mode provides the maximum lighting performance of the light bar but is not E-approved.
The curved shape gives the Alfa21 Gen2 Curved a more integrated appearance when installed on the vehicle.
The light bar can be installed using the included side mounting feet or sliding brackets for upright or hanging installation. It can also be mounted using a licence plate bracket or tube mount. A specially designed mounting bracket for the Alfa21 Gen2 Curved is available separately.
The LED light bar is equipped with a 2-pin DTP connector. A compatible DT/DTP relay wiring kit is available separately.
Ledson Connect can be used for a straightforward installation and also provides flexibility for future expansion with additional auxiliary lights or LED light bars.
With an IP69K rating and a pressure equalisation membrane, the light bar is designed to withstand demanding conditions and exposure to water, dirt and changing temperatures.
