I have a Lopolight,masthead tri- I was encouraged not to go for the masthead white version as mixed opinions were either for or against an anchor light so high.
Anyway, the neat and easily visible unit I have has, so far, been reliable- installed summer 2005- but others have had other experiences. search using Google on the ybw.com sites and you will see what I refer to
I like it as masthead bulbs can't blow and current drain is very low. I've kept the incandescent bulb units at deck level as when the engine is running, battery drain is not an issue and this gives me an alternative means of showing nav lights if necessary.
No direct experience but I use an LED anchor light these days which is excellent.
I'm thinking about getting one myself as my old tri-colour is sometimes a bit unreliable. If I was going for a Lopolight tri-colour I think it would have to be the 2.5nm unit as opposed to the 1.0nm. The extra cost and current drain are unlikely to be significant but the visibility should be much better.

That's exactly what I was proposing to do. I *really* want a reliable very low current drain masthead light. The previous one self destructed in a gale.
Lopolights came out well as did Aqua Signal S32 equalling the incandescent bulb for brightness and performing better at 25% inclined. Cost might only be justified for those planning a long passage.
Anchor light not tested.
LED bulbs generally need further development to achieve adequate brightness. The Mast Bay 15D replacement bulb was "disappointing".
A big torch stood out the best if you want to attract attention.
You obviously have not read the test. It was a practical test of visibility against the IRPCS for requirements for vessels 7-20 metres. Comparative in the sense that all the lights were tested in the same location at the same time and observed by a number of people. The requirement is for visibility, but there is not an "objective" definition of visibility, so you can only determine if people can see it or not. They did attempt to grade the level of visibility and compare with other light sources.
Lopolight came out as "best", but most expensive.
whipper_snapper. Pop into your local Smiths and read it for free, but you should really spend the £3.60 if you are thinking of spending £270 and want some independent information on the product!
I agree that this technology still has a step improvement and cost reduction to make. That's why I will not be replacing all lights. But for long distance cruising I think a masthead light that uses minimal power and is rugged, is a sound investment. I had a close encounter after I lost all nav lights in a gale due to a combination of extreme motion and solid water.
So I think I will go for it. On reflection, I agree the anchor light option is a bit pointless. I was thinking of it as an emergency 'steaming' light as a conventional masthead white can (sort of) be. But with this design, if you loose one you probably loose both.
I have an Orca Green I bought 2 years ago, mainly because they are USCG approved.
It is excellent, and I can recommend it.
Yessss, a little bit expensive!
Nasa had a tri-colour on display at the Paris Boat Show. It looked like the Lopolight but was a fraction of the price. It hasn't appeared on their website yet but perhaps it will be at ExCel.
