IMHO they should be like hedgehogs or christmas trees. All over the ball, but they still flash when in one's eye, and that's when they're on.
My belief is that a constant light AND a hedgehog of LED's would be better than just a constant.

LED's are ok to see with but, because of their directionality, not much good to be seen by.

Take a lighthouse for example. All the light in the world but not much good unless it's pointing at you. Five degrees off horizontal and it's invisible.

Same for LED's.

As you said Kevin.......
Should've known better .... but

Would accept all of that if the light source were presented through a straight lens, however, if presented through a multi-ridged, multi-directional lens you would surely receive the presented beam through the sequence of angled ridges ? and .... whilst in theory, there's the possibility that the angled beam generated by each ridge will have a finite (narrow) direction, the interval between loss and recovery of the light source would be neglible ?

Are you stating there's a specific regulation rendering LED's of whatever application are non-compliant, or offering a theory as to the possibility ? If the former, there are numerous marine manufacturers marketing some very expensive, non-compliant lighting, fitted to some seriously priced new RIBs !

Should have stuck to my mantra .....

There are numerous manufacturers selling non-compliant lighting.

A few years ago our state maritime rules in New South Wales Australia stated LED lighting was non compliant.

That has now been changed and their are quite a few purpose built LED lights that are compliant with our rules which are supposedly based on international rules.

There are also lots of non compliant LED navigation lights for sale and in our case the compliant ones are clearly marked.

I have never heard if a boating officer complaining about non compliant lights if they look right and work.

But as I said in the last post - are you quoting a regulation that LEDs are 'non-compliant' in all forms or offering a theory that they 'might be' ?

I've been fitting Hella "NaviLED" since about 2007, never had a failure, they meet the regs for my size of boat, and customers prefer them. They have the CE mark on them, so as far as I'm concerned, they're fine.

OK, let me say that all LED's are non-compliant.

I'll stand by that.
