Cockpit Lighting Plan LED24v

I extended the Bimini structure (Stamoid type material) for my walk-in cockpit to accommodate the large solar panels.
The area is now quite large and I need to make a Lighting Plan for 24v LED lights as we still live outside in the tropics in the Rainy Season.
Basically, two Lighting Zones: (See Photo)
Aft Outside Cooking Area: S-1 & P-1
Dinning Seating Area: S-2 / S-3 & P-2 / P-3
From where I would position the downlights
2.4 m between Zone 1 and Zone 2
1.9m between Zone 2 and Zone 3
I have no experience using LED Lights.
For calculating the LUMENS strength needed for down lighting, does it compare with Incandescent per wattage?
Any recommendation for 6 pcs Small, Light, Low Profile 24V outdoor LED light fixtures as I want to run wiring next week
Thanks.

Re: Cockpit Lighting Plan LED24v

I did some research last night and found this waterproof 24v strip light available in various intensity.

Still Working thru intensity level but it they do provide a dimmer.

Anyone with experience using these?

Available in Warm White

I have installed flexible LED under cabinet lighting in my office and kitchen. I used strips spanning the entire distance of work / prep area, they are installed approx. 2 feet above the work / prep area and are advertised at as 380 lumens per foot, 9 to 14 volts DC. At 380 lumens per foot I would say the light intensity is very good. For your use I would want something in the 380 lumins per foot range. The lights in this pic are not what I used but something you may want to consider. I didn't need waterproof lights. The web site is SuperbrightLED.com For a 8x8 foot area I would start with two 8 foot runs or equivalent. You could end up wanting more.

Re: Cockpit Lighting Plan LED24v

Pelagic-
I'm not sure if this helps you, but I'm looking at the box for a new "100W equivalent" LED light bulb. It says 1500 lumens, 14 watts, equal to a 100W conventional light bulb.
Now some of us would call a 100W light bulb adequate for a single room, others might want 3x-4x that much light, so your personal choice makes a big difference. If you have too much light, surely you can always find someplace else to move the excess light strips?

And you might beware dimmers. They tend to make RFI and with all the wire running around the cockpit, that probably will get into the instruments and electronics. Inexpensive dimmers generally are loud RFI sources. bare LEDs themselves, with no dimmer circuits, tend to be RFI silent. (Their power controllers can still cause RFI, look for certifications, UL, CE, FCC, that indicate some level of compliance, or ask the vendor.)

Re: Cockpit Lighting Plan LED24v

Thanks Laangus & hellosailor, great input and options as I have a friend in Kansas who can bring the parts to Subic.

This is the simple dimner I was considering
http://www.ecolocityled.com/product/...d_light_dimmer
Ecolocity's light products are UL certified but I don't know about this dimmer. They have many more sophisticated ones with remotes and smart phone control.

Basically, the lights won't be used underway, just at anchor for meals. My thoughts would be to make bright enough for Tasks, but dim for ambience


This photo shows the original Bimini and lights around our cockpit table.

Traditional but not practical for Sun or Rain protection when you live aboard in the Tropics.Click image for larger version

Re: Cockpit Lighting Plan LED24v

Speaking of rain or shine...You might want to make sure there is some kind of water resistance rating on those LEDs, strips, whatever they are. Even if the Bimini keeps them dry, an IP65 or similar rating will help keep salt air from rotting things out.

Looks like your original was just there to prevent heatstroke while cruising. Not an unreasonable goal.(G)

Re: Cockpit Lighting Plan LED24v

Yes the Ecolocity lights have an IP 68 waterproof rating and CertificationUL Listed, RoHS, CE.

Yes the original Bimini had only useable cover at the helm but with zip on extension at anchor.

Love the new stamoid vinyl one, totally waterproof that wraps around the aft mast and is strong enough to walk on,

It can be reduced to smaller sections if needed.

Designed my own Solar Frame that hinges up for maintenance using the topping lift yet seals and is bolted down on the angled stainless studs above flat bar on top of the hand holds.
Makes a perfect weather seal when the Bimini acts as a gasket[

Re: Cockpit Lighting Plan LED24v

I am using aluminum channels for regular LED strips. I use the waterproof strips outside even when protected by the channel. There is also a 45 degree angled version if you want to mount it to the side of something.

In your case you could stick them up against the bimini using 3M VHB tape.

[/QUOTE]

Hi Nick, ...thanks!....that's exactly what I have in mind.

In the product description section of this one it says it comes with base already lined with the 3M VHB tape.

http://www.ecolocityled.com/product/...rip_warm_white

If I don't find anything better, I will order on Monday

The tape gives me a lot of flexibility and I will play with mounting light so it reflects indirectly off of my yellow vinyl ceiling .

Re: Cockpit Lighting Plan LED24v

To replace a 100-watt incandescent bulb, look for an LED that gives you about 1600 lumens.
Replace a 75W bulb with an LED bulb that gives you about 1100 lumens.
Replace a 60W bulb with an LED bulb that gives you about 800 lumens
Replace a 40W bulb with an LED bulb that gives you about 450 lumens

Thanks Gord, that is exactly the information I needed to finalize order.

Re: Cockpit Lighting Plan LED24v

Pelagic, those cheap (warm) LED waterproof strips are terrific. I started using them years ago and all have stood up fine. Today they are even better and the light is almost the same as incandescent (a nice warm glow). If you want two settings (bright for cockpit work and dim for dining) an easy solution is having two switches: one that turns on a few and another that turns on the rest. When you dine you just turn on part of the lights. I've done this in a number of spots on the boat using a simple 3-way switch. You can cut these strips and set them at 13 or 14 volts to avoid shortening their lifespan when you charge the batteries (although if you charge with solar and only use the lights at night it's not an issue). My electric guy builds beautiful LED lights (using LED strips) and light fixtures from the aluminum profiles for shower boxes.

Re: Cockpit Lighting Plan LED24v

The LED strip you show is what I put inside the aluminum channels that I linked to. This provides better (mechanical) protection and ensures that they don't fall off. I am pretty sure that the LED strip adhesive tape will not stick where you want. Even on new clean smooth awlgripped surface, I have it come off at places. The aluminum channel with the (window construction rated) VHB tape won't come off.

Re: Cockpit Lighting Plan LED24v

Nick,
Cant' tell in the description of the channel, but is there any light quality/brightness loss from the channel cover?
