The numbers refer to the physical size of the individual LEDs (so 3528
is 3.5mm x 2.8mm, 5050 is 5mm x 5mm). 5050, being bigger, will both
cast more light and use more power.
I just replaced one fluorescent fixture by making a replacement with 3
feet of 120 LED per meter material, 3528 size. (yes, I am mixing
imperial and metric units...). 3 LED/inch = 108 LEDs It seems more
than bright enough.
I am pondering mounting some 60 LED/m strips on the underside of the
shelves in the v-berth, since that area is a bit dark...
Anyone wanting to look at the various options, the web site
superbrightleds.com is a good resource.

I bought 16 feet of LED's from LED Wholesalers in Calif. They are the
warm white 3528. They are quite yellow. There are 15 LED's per
foot. I installed 30 of them in an old florescent fixture. While
it is a nice light it does not put out enough light to be an area
light in the galley. I am sure that if I installed long strips of
them as hidden accent lights they would be great.

They have a "warm white" but they appeared yellow, like YELLOW, not
incandescent. To be honest I don't know how accurate their colour
temperatures are. I picked the "in between" one because I figure this
is a test and I'll know I can go colder or warmer from this point.

Steve -- 4500K is a fairly bright, bluish-white light (daylight is
about 6500K). If they have something in closer to 2700K or even
3200K, that would be a much warmer-colored light, more like incandescent.
Something to think about.

Hi All.
I just volunteered my boat for a test case using these LED strip
lights that are available on ebay cheap out of china. I haven't
seen them used on boats before. They are marketed as being
waterproof. There are a few variations on the LED types with the
two most common being "SMD 5050" and "SMD 3528". The 5050 have
triple LEDs so they can be made into any colour, they are also
brighter because of the triple LED and consume more. The 3528,
which I ordered, are smaller, single cell LEDs and consume less
(why I chose them). Both varieties come in 5 meter lengths for
about $20. The 3528 strip that I ordered has 600 LEDs on it! They
can be cut to size. I purchased these to provide accent lighting
in the cabin. They should be bright enough to be used as a primary
light source for hanging out but not for reading (not the way I'm
installing them, anyway).
For the accent lighting I'll be installing them behind the teak
trim on both sides of the boat just under the cabinets on either
side. They should be hidden from view in there and I will likely
aim them UP into that void rather than down, I'm a big fan of
diffused lighting. I ordered the "natural white 4500k" LEDs. What
I'm hoping to accomplish is a nice subdued ambient light in the
cabin. I might even try a dimmer.
If anyone is interested in this I can update once received and
installed.
Check them out:

For $20 I figure it's worth the gamble. They are 12V DC so should
be a snap to install.
I've got other ideas too. I'll see how this first strip works out
and I'm curious to see what the real world power consumption is.
