PAR 36 Is 4.5 Inches, and the 36 Is Why
PAR 36 is not a model code. The number is the front diameter counted in eighths of an inch, which makes every PAR 36 exactly 4.5 inches and a 4-inch PAR 36 a thing that does not exist.
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.

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.

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.
