The complete guide to choosing a Lazer ST/T Evolution light bar
The letters in ST/T Evolution mark a real split in what each half of the range is built to do, and mixing them up is the most common mistake buyers make. ST models are road-legal driving lights, built to connect to a vehicle's existing high beam circuit; T models are larger off-road light bars intended for static or off-highway use. Both share the same LED and optic technology, so the decision is about application and approval, not build quality.
Within ST, the range runs from the compact ST-2 at 2,068 lumens up to the ST-12 at 12,408 lumens, sized to fit anything from a grille-mounted supplementary light to a full driving light setup on a 4x4 or light commercial vehicle. T Evolution scales further, from the T-16 at 16,544 lumens to the T-28 at 28,952 lumens, aimed at working vehicles and off-road applications where a wider, longer light bar makes sense. Both ranges use the same 'Drive' beam pattern, delivering a wide spread of light rather than a tight, narrow throw, which is what makes them well suited to rural road use and off-road terrain where hazards can appear from the side as easily as ahead. Both ranges also share the same 5000K colour temperature and 80 CRI rating, so colour rendering and definition stay consistent whichever model you choose.
Every unit in the range carries a 5-year warranty and IP68 sealing, protecting against dust and submersion up to 1.5 metres, and is designed for compatibility with Lazer's Canny CAN interface for wiring into OEM vehicle controls. If your application needs Lazer's dual-output or i-LBA functionality, the Triple-R and Linear ranges cover those features; the full Lazer Lamps collection brings every range together in one place.

Frequently Asked Questions
What is the difference between ST Evolution and T Evolution?
ST Evolution models are road-legal driving lights, built to connect to a vehicle's existing high beam circuit and carry UNECE Reg 112 approval where applicable. T Evolution models are larger off-road light bars for static or off-highway use only, not approved for connection to a vehicle's road lighting circuit. Both use the same LED and optic technology.
What sizes are available in the ST/T Evolution range?
ST Evolution runs from the ST-2 at 2,068 lumens up to the ST-12 at 12,408 lumens. T Evolution scales up further, from the T-16 at 16,544 lumens to the T-28 at 28,952 lumens, for larger off-road applications.
What does the 'Drive' beam pattern mean?
The Drive beam pattern delivers a wide horizontal and vertical spread of light rather than a narrow, concentrated throw. This suits rural road and off-road use, where hazards can appear from the side of the vehicle as well as directly ahead.
Are ST Evolution lights road legal in the UK?
ST Evolution models carrying UNECE Reg 112 approval are road legal when wired to the vehicle's high beam circuit and fitted within the approved beam angle. T Evolution models are for off-road or static use only. Check the specific product listing for its approval status before fitting.
