Look away now if you don't like underwater lights/think they're bling/etc :-) /forums/images/graemlins/grin.gif

The www.Lumishore.com folks installed uprated drivers on my boat last week. For the uninitiated, which includes me, a driver is a box of electronics that supplies power to LED lights and controls the current to them and switches them on/off thousands of times a second which is how you dim them, etc. Also, where you have separately driven RGB lights the drivers contol the mixing of R,G and B so that you can dial in any colour you want, or set them to cycle slowly thru the rainbow.

They wanted to get some photos so we took the boat round to the little bay on the SW tip of Cap D'Antibes and stationed a cameraman on the rocks. These photos aren't great, esp as there was a swell and the boat was rocking so we couldn't do long exposures. But they were good for practice and we'll get better photos when we get luckier with the weather. Anyway, the pics do show the power of these lights - the beam really does spread 20m from the transom as shown in these pics, perfect for night swimming as I discovered the next evening. (And in these pics they weren't on full power; they were on about 60%)

There are also a pair of lower power lights on the tender. The second last picture shows the rock face illuminated by the tender's lights

Finally we fitted the new Lumishore control pads. These are beautifully made with blue LCD dot-matrix displays in a stainless steel case. We fitted two - one on the flybr helm (top right round thing on pic below) and one on the lower aft deck

Lumishore have put up another video here taken in the same session. This shows the colour change (and also the swell that we had to put up with!). Another video of just the tender (with my son doing illuminated water sprays) is here. The first video take a few weeks ago, underway, is here

How many lights on the dinghy? I have one fitted, a single one, but havent launched the dinghy yet, it looks great!! Hope mine looks as good as that, havent go them on the boat, too blingy for Englander, but fine for the tender!!
 
There are two on the dinghy. Not sure what power they are though. EME will know - he'll chime in later I guess

They're not too blingy for Englander. You can switch em off much of the time, but when you want a night time swim they're beautiful. Lots of classic boats that are concerned about blingyness (s/y Meteor comes to mind) have them

Power-wise, in the stills above they are drawing 12amps at 24v. At full tilt they can draw 20amps but you don't need that much light and will probably confuse aeroplanes and things :-). About 60% of full power looks the biz.

White doesn't look great: colours look better. A choice of colours is nicer than just one, becuase you can choose the colour depending on what mood you're in! Blue, cyan, green all look stunning imho. I mostly have them on the slow cycling thru the rainbow cycle. It entertains folks at dinner!

All that said, I wouldn't pick a fight with you: I quite understnad that many people dislike uw lights or think they're unsuitable for their boats/boating. All fine. I'm showing the pics for those who do happen to like them or like looking at them, and to show a really nice bit of engineering by a new UK company - there really is some serious engineering (mechanical, electronic, specific LED technology) in getting that much of a light beam with that much control from just 12amps @24v and full credit to Lumishore for developing this as a start up
 
Aaargh - if only you appreciated the (UK) engineering that has gone into these hicob LED arrays, which is 1million times more complex than buying a blue capsule LED from china/maplins and soldering it onto a washer jet accessory. You blimmin philistine Pete! :-)
 
Drop by? I'll be there fri night till sun night. Possible monday too, cos I got glitches getting all the raymarine gear to talk to each other and I might need to be on the phone to the helpline during office hours... :-)
 
Seriously good. I particularly liked the shots of the dinghy lit from behind so you could see the full uw profile as if the water wasn't there.

Not enough nekkid women though.
 
When you had the lights on did you notice any increase in fish activity? If so was any particular colour more attractive to them?

Get yourself a fishing rod, and some hokie or sabiki lures, you will never again be short of squid.

Forget Sabikis for squid, find deep water, stick a 10/0 circle on and wait for the Swordfish to follow the squid up.

I must say I like those lights, far superior to others I have been looking at. I feel a purchase should be made...
 
I think they are absolutely stunning ... enough justification to buy a boat just to have Lumishore lights.

Englander The lights on JFM's rib are the same wattage as yours (36), the only difference being that he has Drivelites and you have a Riblite (Drain Plug Replacement).

Forbsie You know you want to be the first on the Lower Thames to fit some. Only word of advice ... dont switch them on when you're coming back from the pub. The River Police will see them! /forums/images/graemlins/cool.gif

Sultans_Kapitein I believe 'White light' is just what we are used to. It is the only option with traditional lighting where lenses are generally used to create 'colour'. LED lighting doesnt need lenses to create colour. White light works best with crystal clear water and light sandy bottoms - Blue for most applications - Green for dirty water such as lakes and ( the shame) the Bristol Channel. Red works in all environments although our best results have been in the Bristol Channel .

With our system you dont have to choose the colour you want just choose from 1 of the preset colours (including white ), put it into cycle mode ( JFM's personal favourite is the fastest cycle speed), or dial in your own colour combination. I've just realised I dont have any pictures of White on this photoshoot. /forums/images/graemlins/blush.gif I'll find some and post them up.

LongJohnSilver The 4 fish attraction modes are 2 Blue and 2 Green modes. We did some research into the University of Wisconsin work on correct wavelengths that fish see etc and why we went for Green & Blue. The modes can actually be changed with respect to speed of flash as it still seems unclear from those we've spoken to, and articles we've read, precisely why strobing attracts fish so the optimum speed is still a mystery ( to us at least and I cant find a fish to interview) so the owner/operator can adjust for themselves. The modes include random flash rates.

BTW -- MBY kindly featured us in a product review this month -- Im sure we all bought a copy!
 
I haven't done a proper study but as a general comment I get lots of fish coming up to the lights with green and blue light. This is with solid light - I can't comment on strobe lighting becuase believe me once it's been on for more than 15 seconds you want to turn it off as it feels like it'll give you a headache!

I had the lights on in very still water overnight anchoring on sunday and a beautiful 1m long eel came up and hung arouind for a while. Also I could hear lots of busy fish activity. I got a bit of a twang of conscience cos I thought I might be attracting the little fish and then all the preying fish were lurking ready to pounce on them, nicely herded together. I thought the jumping and splashing activity I could see and hear might be the small fish escaping when attacked...

But overall, I'd say (on a gut feeling not scientific basis) they attract fish
 
Stunning, the tender and mother ship together look stunning.

Not going to get lost from the MY in an anchorage on your tender and using a specific colour for both then you can see it is the TT to the MY boat a mile off ;-)
