I just stumbled across these mast head LEDs and they appear to be very good value at around £50 http://www.nasamarine.com/proddetail.php?prod=Supernova

Has anyone got any experience of these? The nearest similar product is around £200 I wonder how they compare to those?

I couldn't see from the literature, but does anyone know if they could be mounted on top of each other - a masthead white on the top with a tricolour below it?
 
Nasa specs for lights say they have a visibility of "25 degrees above and below the centerline ."

I presume this means a total arc of 50 degrees.

I can't remember many angle of heel details but NASA's 50 degrees should make it quite a useful product.
 
I bought one of these and to a 1st approximation, and my satisfaction, it meets both the horizontal and vertical angular visibility requirements of the IRPCS.
Your statement is potentially libellous unless, of course, you have photometric evidence to back it!
 
At the moment I have nothing up there! (I'm just starting a refit and the old mast head lights have gone walkabout). I will be replacing the fore and aft lights with the LED bulbs you mentioned.
 
i replaced my masthead with these during this refit - not yet mounted but tested and fitted on the mast. They appear well made, bright enough to scare the dog, the hriozontal zone of sight appears significant , though I have never measured it. At the end of the day they are much better than the crazed lump of plastic they replace and do not suffer the colour shift that you will find with using an LED replacement white lamp in a standard fitting.
 
I bought the all-round white. Not fitted it yet, but it looks good quality. Unfortunately the design means you cant easily mount one above another.
I think I might have seen some article in PBO about somebody modifying one to acheive this, but probably more bother than its worth.
 
I contacted nasa too about this, and was told "No easy way of doing this as weren't designed with this in mind"

But I think it could be done with the use of a few home fabricated brackets, a screwdriver and some silicon sealer!

I think it's worth doing, becase it would make a very good set up for a reasonably low cost. no doubt I'd void the warranty!
 
Just done the very thing. mounted a 10mm bighead onto the top of the white with sika, tapped the ally tube on the tri and screwed together.
Found a piece of tube to go between the two and sealed them together with sika. Drill a hole in the tube for the wire of the tri to emerge. Use the supplied mount to mount the whole thing.
Can't send a pic as the light is now at the riggers to go on a mast.
 
Don't honestly see much point in fitting LEDs to Port Stbd and Stern lights ( that's assuming you only use them under power) but I do think changing the ordinary Lamps ( Sparkies tell me emphatically that bulbs grow in the ground!) in the anchor and tricolour for LEDs is worth while..
Main problem i've got is crazing of the lenses andUnable to identify the old lmasthead light fitting.. So its a new "Quickfix Aquasignal and two LEDs this year...

I checked the site, delivery to UK / Ireland only...

Does anybody know where I can get them in the Netherlands?

edit:--- Apologies, should have checked the nasa site first... I did and it is www.technautic.nl - Interestingly enough the price is nearly 3 times the UK price.... can somebody send one to me?????? :-)
 
I fitted a NASA tricolour yesterday on a Contesa 32.

Very east to fit, The alloy mounting bracket supplied is quite good but may be a bit weak longterm, it is quite thin.

Although NASA have not designed them to fit on top of each other it should not be too make a bracket to do this.

One thing I don't like about it is that there is a flying lead thus the electrical connections needed the use of heat shrink and self amalgimating tape to protect it.

Perhaps a small waterproof box should have been supplied with it, even ad an optional extra.

I will probably get a pair for myself.

What would stop you turning the anchor light upside down and glueing it to the tricolour?

Could we then seal the cable with epoxy, as it only pulls 200mA it could be changed to bell wire as it passes the tricolour so making no shadow at all?

I am interested in these too, but would like to mount both, what do people think who have seen the actual units up close?

Or, cutting the stub off the anchor, drill a small hole through the tricolour, feeding the the wire through and glueing it the right way up, then the cables for both will now both come through the stub on the bottom of the tri?

In fact, if you have one, and a digi camera, would you mind photographing it all over and sending the shots to this thread, it will teach you to use your macro /forums/images/graemlins/grin.gif so I can see how they are put together before taking the chance on being able to make them work for me?

That's exactly what i was thinking of. I'll have a go at it sometime in the future.
