Field notes

How this gear actually behaves

Not product announcements. The questions that decide a build: what fails in a switch when it fails, how much current a circuit really draws, and which number on a lighting spec sheet is the one that matters at 90km/h.

  • Nobody sends a light bar back for being dim

    Every enquiry opens with the emitter question — which chip, how many. The claims that arrive a year later are almost never about brightness. Both deserve a straight answer, and they are not the same question.

  • The antenna is the only new decision

    If your fitters can install a wired panel, they can install this one. There is exactly one part in the box they have not met before, and it is more forgiving than it looks.

  • The app does not add features. It adds a second door.

    Buyers ask whether the Bluetooth version is worth stocking. The honest answer is not the one that sells more modules — the app opens a second way into hardware that already does the work.

  • Your logo goes on in an afternoon. The rest is the work.

    Every supplier will tell you to send your logo. That part takes an afternoon. Defining the product, and working out which certificates cover which markets, is the part that decides whether the programme survives its first year.

  • Wireless + Wired: The 8-Gang Switch System 4WD Owners Actually Want

    Eight circuits, and the worst part was never the switches — it was the loom. This system runs one feed to a control box near the battery, and puts two panels wherever you actually need them.

  • Same 40W, same 6,000 lumens, 65 metres or 400

    Three lamps on our own range run the same 40W, the same Osram emitters and the same 6,000 lumens. One reaches 65 metres and one reaches 400. Nothing is wrong with either number — the optic is doing it.

  • The switch panel decides what the rest of the build can do

    Lights get chosen first and switching gets chosen last, usually from whatever is left in the budget. That order is backwards, and you find out which way round it should have been about a year in.

  • 4, 6, 8 or 12 circuits: sizing a switch panel

    Eight channels rated 130A, on a panel that passes 60A. Both numbers are right, and the gap between them is what decides whether a build works.

  • Wiring an 8-gang switch panel: what goes where

    The control box lives in the engine bay, the panel lives on the dash, and the only thing crossing the firewall is a signal cable. Get that structure right and the rest is tidy work.

  • Lumens buy brightness. They do not buy distance.

    Two lamps on our own range make exactly the same 9,000 lumens. One reaches 450 metres, the other 700. The lumen figure did not tell you that, and it is the figure most spec sheets lead with.
