Replacing Tricolour - LED or normal fitting with LED bulb

[Tintin]

Thanks for the help. I went looking on ebay for a Series 34 LED tri / anchor and got very lucky - new one for £72

So applying the sale logic often used by my wife I now have about £130 extra to spend on other stuff

Grrr!

I found a masthead/anchorlight series 34 on ebay last week, but I do not think that this is the same as a tricolour/anchorlight combination. Might be worth double checking if you found the same one as me.

I might make myself unpopular here.
The Colregs specify
"The intensities shall decrease to reach practical cut-off between 1 degree and 3 degrees outside the prescribed sectors".
(Annex 1 , 3).
It's far from obvious that LEDs can do this, and I have seen no evidence that they can.
If a tricolour is viewed from ahead, and the red and green don't cut off cleanly, a combination of green and red adding up to something like white could be see, which is not the message you might wish to convey.
An all-round light might be OK, however.
(There are also requirements for spectral content of the light, and I'm not convinced here either, though it might be technically possible.)
Yes, I know that the lights are claimed to satisfy the Colregs. But I just don't see how this is possible.
Has anyone done actual measurements?

Perhaps things have changed but, at Metz a few years ago, the Lopolight red was visible 20° into the green and vice versa. Staff unwilling to discuss.

Surely the cut-off is/should be determined by physical barriers?

20 degrees seems an awful lot, but with multiple LED sources it is hard to get as clean a cut-off as you get with a vertical filament of say 1mm diameter and a housing of say 50mm.
1 in 50 is 1 and a bit degrees.
Even a good autopilot wanders by a few degrees.

Tempting to get a bunch of LED's and a pot of clear cast resin is it not?

Oh bugger! Note to self etc..........

The people claiming the LED lights meet COLREGS ?

I was very happy with my NASA Supernova. I was astounded how bright it looked at the marina when several other boats also tested their nav lights.
