Panther Heat S540
The Panther for the worst nights. A tempered-glass lens heats itself so slush and ice never dim the beam, and underneath it is the most powerful 54-centimetre Panther: 17,795 measured lumens and 750 metres at one lux.

Fitting guide
An evening in the garage.
Bracket, harness, trigger, aim. Here is the whole job in order — most owners say it took them an hour or two.
Installation manual (PDF)- 01
Pick the spot, then the bracket
Under the number plate with the EU-plate bracket, in the grille, or on a bull bar with a tube mount. End legs and width-adjustable bottom legs are in the box; the panel has ready places for stabilizers.
- 02
Use the relay harness
Run the Pro Serie relay harness from the battery: red to +, black to the chassis, the fused relay next to the battery. The light's DTP connector clicks straight into it.
- 03
Take the trigger from the high beam
The harness's thin trigger wire taps the car's high-beam feed, so the light follows your stalk. On a halogen car that is one connector.
- 04
LED headlights or CAN bus? Use XBB
Newer cars switch the high beam over the CAN bus. Plug the XBB Dongle into the OBD port and the PowerUnit relay into the Dualrelay harness: it reads the high-beam signal wirelessly, no cutting into looms.
- 05
Wire the parking light
The yellow (orange) and white wires are the two-colour parking light. Connect one of them to the car's position-light feed — or both to a switch and choose by mood.
- 06
Choose the mode
Press the button on the end of the bar to switch between road mode and PowerBoost®. The last mode is remembered.
- 07
Aim it
On a flat stretch at night, adjust the light so the top edge of the beam sits level with the car's own high beam. Tighten the stabilizer bars so it stays there on gravel.
- 08
Stay inside the rules
Under ECE R48 the combined reference number of all high beams on a car — the originals included — may not exceed 100. This light is Ref. 30: check the marking on your headlamps before adding more.
- 09
Wire the heater
The green wire powers the lens heating. Take it from the position-light feed or the high-beam trigger so the glass is warm before you need it — it draws 46 W.
Keeping it like new
Wash the lens, don't scrape it
Polycarbonate scratches. Soak road salt off with water before wiping, and never use an ice scraper on the lens.
Grease the connector
A dab of dielectric grease on the DTP pins keeps winter out of the connector for years.
Check the bolts after the first week
Brackets settle. One turn on the stabilizer and foot bolts after the first 500 km stops the rattle before it starts.
PowerBoost is for off-road
Road-traffic approval covers the road mode only. Switch to PowerBoost on forest roads and closed tracks.
Owner tips
- Mount it high if you can
One owner who fitted it under the plate recommends mounting above the bumper to get the most from the beam.
- Heat on the trigger
Wiring the heater to the high-beam trigger means it only draws power when the light is on.
- Stone guard anyway
Glass is tough but not immune. The Panther S540 guard fits.
- Road mode is quieter
3,103 lm and 319 m in road mode — plenty for traffic, with PowerBoost one press away.
Measured, not promised
The numbers from the lab.
Every Purelux is measured in Valostore's light laboratory in Oulu: output, range at 1 and 0.25 lux, power draw and colour temperature. We publish what we measured, even when it is lower than the box.
Measured output is 0 % below the manufacturer's declared figure — and that is the number we publish. Colour temperature 5,001 K measured; range 750 m at 1 lux and 1,500 m at 0.25 lux.
Modes · output, range and power — measured
Range is the distance at which the beam still delivers 1 lux (roughly a full moon) or 0.25 lux. Measured at 24 V with a clean lens; full lab curves are available to professional buyers on request.
Why Panther Heat
Snow on the lens. Still 750 metres.
Every LED bar has the same weakness: LEDs run cool, so the slush that lands on the lens stays there and the beam shrinks to a glow. Panther Heat answers it with a tempered-glass lens and a heating element that keeps it clear — automatically, whenever it is powered.
Behind the glass is the strongest 54-centimetre Panther. Valostore measured 17,795 lumens, five lumens short of the number on the box, and 750 metres at one lux. The road mode is an E-approved Ref. 30 light.
It is the bar for the gravel commute, the plough truck and anyone who refuses to stop and wipe.

From people who fitted one
Owners on the Panther Heat S540
“I think it is the most powerful LED bar of this size. Extremely powerful without any exaggeration — I recommend it.”
“Really good output and beam pattern. Price–quality is excellent, and the heated lens with its own trigger wire is pure plus.”
“Swapped an older 70 W brand bar for this and hell, does it shine. Mounted under the plate; to get the most out of it, mount it above if you can.”
“Brilliant package. The beam has both width and reach.”
“Fitted flush in a 2026 Octavia with the XBB kit. Plenty of light. Just be careful when you cut into new cars — lots of cable and sensors hiding.”
“Exactly what it is advertised to be. Output is more than enough.”
