Underwater lights

There is nothing that is in anyway technically better than or even equal to Lumishore. They are absolutely the best, bar none, absolute fact

It is not just a question of sticking HI leds in a w/proof housing. At these power levels there is a bunch of heat management, and there is also a challenge in getting efficiency ie highest lumens per what so you don't whack your batteries. Lumishore does this. The others just take capsule LEDs like Maplin catalogue and stick them in a w/proof housing, as you say

Howver Lumishore isn't the cheapest so if you want low price you will have to go to another supplier. Although, Lumishore is so bright it is pretty much the cheapest per lumen. There is a "forum discount" I think from EME so it's worth asking him

When looking at brightness "scores" to compare products do not look at lux (light intensity). Any manufacturer who quotes lux is playing tricks and shouldn't be trusted. Lumens (light quantity) is what counts

BTW John, what's the deal with leaving underwater lights on when running, is there some sort of problem with doing that? I saw that another vendor (OceanLED) advertises theirs as "the only underwater lights designed to be left on" but I can't think why any make of underwater lights can't be left on when running...

Always happy to help . . . ;)

I think candles in jam jars would be the best economic option. The key benefit of this is that you can also use the jam jars to catch shrimps & the candles to cook 'em.

I am impressed that you are so bored with safe sailing that you need to cut lots of holes in the bottom of your boat to add excitement. Lots of pointless electrickery too, that will add many benefits 10 years down the line. Ahh, I forgot, you guys change your boats twice a year anyway don't you.

I usually stay clear of these threads for obvious reasons. :)

However you have suggested an 'advantage' a competitor light has that we dont. Nonsense... BS .. if that is what is they claim.

Our lights (without exception) all operate whilst 'running'. In fact they also have built in software managing heat/output so much better by far than our competitors in terms of capability.

Outputs speak for themselves but always available to clarify some of the BS others put out .

Balearick the lumishores rely on seawater to cool them, but when in water they can be on 24/7, whether stopped or underway (underway, if you hang over the back of the boat and look, even when rnoving fast on the plane, you will see there is enough water spray/slosh on the transom to cool them and so even my 120watt lumishores get enough cooling and can be used when underway, continuously). However, if you left them on just in air, they would overheat and turn themselves off (automtic turn-off) in a few minutes.

As for OceanLED, my preceding snetence does of course form the basis for their "claim". Theirs can indeed be left on continously, even in air. But that's becuase they produce so little light that their need for heat management is non existent, so of course they can make that claim, just as a manufacturer of a 99p LED torch can. Applications with low light outputs can use air cooling; job done. But it isn't an achievement! If you dim lumishores (which the controller lets you do) to OceanLED levels of light outut, then sure you can run them continously in air. Hence, their claim "only ones designed to be left on" might be literally true but is disingenuous. They re good a BS over at OceanLED though :) BTW, I call them "tea lights" :)

Just to be crystal clear - in water the lumishores can be left on 24/7, anchored or underway. I run mine for 6 or 7 hours some evenings. The BS from OceanLED complements the quality of their hardware.

No worries, SR. A brand new surface mount version is now available, so you've got an opportunity to not miss the excitement, eventually...
Btw, I'd rather have the shrimps raw than candle cooked... :)

+1 on SR, I'm trying to reduce the number of holes below waterline from 7-8odd to 5, so not looking fwd to drilling more.

+1 on MM on the shrimps though ;)
 
Lights

I have been told they are good for fishing, they swim towards the light, so can be dual purpose.

was thinking of getting some, but dont like the idea of drilling holes in the hull.

Dont know the cost of them, but would think about getting a set or two.

Never been accused of no SOH before :o I think that is 1-0 to you :o And many apologies for missing it !

Edit: and I happen to enjoy sailing as well ..... and many are customers

Right on cue!
Searush you must be like a meerkat! At the very mention of your name you're out of your misenfocstlemast thinghy with your little ears twitching and nostrils flaring!
( sorry I've never met you before but you do make me laugh and I just knew you were a fan of underwater lights)

Heh! But really it's the same reason swimming pools have lights. Not necessarily for night swimming but because a lit pool looks so gorgeous and so is a pleasure to sit by sipping a beer in the evening. If you're spending the evening sitting on the back of your boat having dinner or a beer, unless you're in a marina you're sitting in a black hole - much nicer to be surrounded by an underwater spectacle with the light dancing off your hull... at least I think so.

(I do appreciate the valid point about making holes in your hull)
 
I'm not sure where I stand on underwater lights. I can't decide if they are a total, "hey look at me everyone" decadence or actually quite cool.

I think the swimming pool analogy was a good one. There is also no doubt that they attract marine life. Anyone who's been to Thaialnd will have seen fishing boats at night with lights glaring.


I suppose the answer is if I bought a boat fitted with underwater lights would I turn them on? Yes is the answer. Would I pay money to fit them myself? Not sure. I have it in my head they're rather expensive. - not that I've ever priced them up.

There's a P54 at the end of our pontoon in Haslar with them and the fish love them. I watched fish jump on the end of the line! I also saw a V52 with them in Weymouth and its was like having your own private aquarium.

I can see the "waste of effort" argument but then you could argue that very little about our pastime is strictly necessary.
