Technical Resources & Guides
In-depth articles on LED work light specifications, certifications, and application guides — written for procurement engineers and equipment manufacturers.
Deck Lights at Night: The Rule Is Not About Brightness
The question is usually asked as whether deck lights are legal under way. The rule sets three conditions instead, and brightness is not one of them.
IP68 for Marine Use: The Test Conditions Are Negotiable
IP68 reads like a fixed threshold. It is not one. The depth and duration behind the mark are agreed case by case, and salt is not in the test at all.
Work Lights on Boats: The Lamp Is Rarely What Fails
Work lights are already being fitted to boats. In our experience the housing copes; it is the bracket, fasteners and cable entry that decide the outcome.
Galvanic Corrosion: Why a Scratch Near the Bracket Is Worse
Two scratches of identical depth can have completely different consequences. What separates them is not the damage but what metal happens to be bolted alongside.
Salt Spray Test Hours: What 240 Hours Does Not Prove
Hours are the number every salt spray report leads with, and on their own they settle almost nothing. The rating standard and the test piece decide the rest.
Anodizing vs Powder Coating: Your Alloy Has Already Decided
Every comparison of these two finishes treats it as a free choice. For a lighting housing it usually is not: the alloy that suits your housing process has already narrowed the answer to one.
Why E-Marked Lamps Still Interfere With Radios and GPS
An E-mark and a buzzing radio are not a contradiction. EMC approval is granted to a single lamp on a test bench; interference happens to a machine carrying eight of them on a shared harness.
Why LED Trailer Lights Fail on Grounds That Worked With Bulbs
Most LED trailer lamps sent back to us as defective are not defective. The fault was on the trailer before the lamps arrived — incandescent bulbs were simply forgiving enough to hide it.
Why OEM Work Lamps Are 5000–5700 K, Not 6500 K
Dust, falling snow and rain change which colour temperature works — and not for the reason usually given. A guide by machine and job: what the conditions do to the light, which kelvin band answers them, and the three specification traps that cost more than the colour choice.
