Do you use the whole string in each application or have you cut them as appropriate?

Frankly, because of the areas I install them, and the way I use them...the entire string of LED's is used. I haven't yet tried to cut one down.

I used about 4 or 5 of the 39" strings to light the countertops and stove in our galley.... The Admiral loves it. I have also used about 5 of them in my engine room...and they are great, and I expect to install another 5 or 6 down there. I also put three of them in my battery/generator compartment. They eliminate the need for flashlights to check the acid levels in the batteries.

One of my POs installed 240V AC fluorescent lights X 4 in the ER space to supplement/replace the poor 12V dome light incandescent globes X 2. They are so good but the Genset has to be rumbling away whilst they are on. Too inconvenient and too loud. Recently I had 12V LED strip lights installed because I didnt want to run the genset every time I entered the ER. They are just as bright and so convenient. The danger is I forget to turn them off. Whilst I have warm white LEDs in the salon cool whites are brighter for the same voltage and are just great for an ER environment. I thoroughly recommend the change to LED lights.

We have a set of 12 VDC incandescent lights in the engine compartment and a set of 120 volt lights in safety fixtures. The 120 V lights are run through the inverter. Flip that switch on and it really provides a great deal of light.

As for entering your engine compartment while underway. Have you considered installing a small remote camera. We purchased a surveillance camera set that I intend to install at least one of the four cameras it came with in the engine room. That way I can take a look any time I wish. The set up came with four camera, a DVR recorder and all the wiring. The cameras have motion sensors so they are great for keeping an eye on the exterior of your boat and they are good for night vision as well.
My ultimate plan is to place one or two in the engine compartment, one will be placed to see the stern and the other to monitor the cockpit for entry protection. At least that is what I plan at this time.
The whole thing cost me $99 on Woot. It did not come with the harddrive for recording but got a 1T DVD harddrive from Ebay for $109 (including shipping). Which installs in the DVR case so no extra things to find a place for.

The rigid LED strips I put into the fluorescent housing were these RLBN-NW30X3SMDNatural WhiteRLBN-NW30X3SMDNatural White5600K20.1 lm342 lm/ft603 lm52019.95RLBN-x30SMD. They can be cut in three inch sections to fit the housings. These wire right into the 12 vdc without any power supplies. Dont forget to by the connectors you need for these.

UPDATE
I installed five 24" LED light bars in Oct 2011. Three have failed. I have sent message to SuperbrightLED to find out what's up. They have a 2 year warranty. The model is discontinued. More to come.

My cheap lights from Ikea have been working well for about 3+ years. Four of them are in the engine compartment and bright enough for the most finicky work. That they swivel a bit is a bonus.

I replaced 4 incandescents with these:

Round Dome Light LED Fixture with 3 Position Switch | Dome Lights | Truck Lights & Lamps | Truck/Trailer | Super Bright LEDs

So far I couldn't be happier. Better light than before, low battery drain, they were inexpensive, no complaints and widh I had done this a long time ago.

Here are the facts:

The only way to determine how much light you will get is to look at lumens. If you want more light than you have now, you need more lumens.

If you want efficiency, you want to look at lumens per watt. LED's typically will offer low wattage, your task is to weed out the junk and find the higher lumens per watt.

Cool White, Warm White, all refer to color temperature. Typically an incandescent lamp is in the range of 2700K. This is considered warm. LED's can range from 2300K to 5000+K. On the 5000K end, the light is very white almost blue (no red in the spectrum) this can give the appearance of giving more light but remember it is all in the lumens.

The LED emitters, generally will have a lifespan of 50-100,000 hours. Compare that to an incandescent of 650 or so hours and you will see the economics. The failure point is in the drivers, some are junk and you don't know what their life is.

Third party evaluations (Energy Star) for replacement lamps, and (DLC) for LED Fixtures, tend to keep the manufacturers honest in their reported life claims backed up by strict testing.

The problem we have in the marine industry, is that the products that have the most flexibility in mounting and design, are not necessarily backed up by any third party testing results so it is buyer beware....

The units had a two year warranty and Superbright replace them free of charge.
