240v LED ropelight is £1 per metre, would the consumption be OK through the invereter? I wanted to use it in the engineroom. Unfortunately 24v is £14 per metre. I could see using it around the deck.

Yes Point taken,
I once bought a set of bino's which were supposed to be marine glass's.
They were excellent during the day time, very bright and crisp.
But the red coating on the lense which made the most of the dusk and dawn light cut down the amount of red light allowed throught the lense at night.
It was very difficult to see red navigation ligths at night, which was a little dangerous to say the least.
Re red nav table lights, your point is very pertinent, and I guess you do have to be aware of this shortcoming. Its your judgement whether you want to loose your night vision for a few minutes or just take a bit more time looking at the chart.
Regards

leds are harsher than conventional bulbs. They use less than 10% of the power for the same output . they run cold. Mostly are highly directional. They last virtually forever.
I adapted tradional brass interior lights. by making up arrays of about 50 white leds and 10 red, to warm up the light colour somewhat. I bought online cheaply, and the resultant is good for general work but not reading. You can also get only white 21 white led arrays as reversing lights on cars, and they are Ok for reading

My Chartlight for night passage use has an amber lens (off a car indicator repeater) Cheap, effective & still lets you see red lines on the chart (there aren't any amber chart markings are there?)

Hi, from Ultraleds, they have the offset type and also the equal pin type, 'UB20WW' is the part number for the offset-pin hella type, cost 14 pounds (about twice that of the filament bulbs), but will last for 50,000 hours, so no more trips to the masthead to change bulbs.

IMHO it is a bit of an energy waster, since you up-convert from 12 V to 230 and back down again in the ropelight.
12V LED ropelight can be had, or more practical, LED bars. At IKEA, you can have "Trettioen", a set of four LED bars. IKEA
Each separate bar runs on 12V, or you can add one bar after the other by just sticking one bar inside the next and fill the lenght of the engine bay, as I did.
(the 230V adapter goes in the project bin).

Leds are very good, gerund grinding is off topic
acshully modern English doesn't have a genitive proper but a possessive clitic. Otherwise we would be unable to work out whether Richard of Asymptote's woman crew belongs to the yacht or the man. I thengu.

Something wrong with the price there!! $49.99 in the USA, and only £21 in rip-off UK. /forums/images/graemlins/shocked.gif
Come on IKEA, get the price right. /forums/images/graemlins/confused.gif

Paul,
From where did you source your overhead spot LED bulb? I am looking to replace those on our dehler 35, and I'm pretty sure they're the same.
BTW, I fitted some flexible LED strip lights inside a couple of gloomy galley lockers last year, and the results are excellent. Stuck them to the underside of the locker shelves with double-sided tape. Provided they light indirectly (i.e. you can't see the glowing LEDs) the ordinary LEDs work very well.
