I made up some 24v units using 3 strings of 8 superbright LEDs. The
output was quite reasonable and uniform but the colour was too blue -
so to the eye not as bright as a more yellow incandescent lamp. Not
wery good to read by.

They supposedly are intended for marine and RV use, and are clearly
cheaper than other LED products I have seen. For all of the talk on
solar panels, generators, etc., I'd be happy finding a way to use less
power (as opposed to generating more).

Great web site! Link to very interesting technical info on LED's.

I wish I could buy from them but theirs are mounted in a thick cannister
intended to be lights on their own. What I like about the ones Steve
originally posted about is that they will fit right into my existing light
fixtures which are fairly large for just two bulbs.

The blue light worries me a bit because I really don't like what comes out
of LED flashlights.

Does anyone know if blue light is the opposite of red light as far as night
vision is concerned?

I don't think I would try this if I only had one bulb in my fixtures but
being able to bring a standard bulb on line to boost output and dilute the
blueness makes it seem reasonable. I'm still going to wait until I can take
my LED flashlight down in the cabin and see how it feels.

I wonder if the amber LED's are more pleasant light? If just faintly amber,
they might be.

I like the idea, but I can't find any 12 volt, medium base. Just those silly
candelabra bases or the bayonette type.

Thanks, Joe. found them at this link: https://www.superbrightleds.com/
Only one available, in either narrow or wide beam. I ordered three of the
wide beams, will let the group know how they work for me.

I've heard that the reason white LEDs seem dimmer is that the light is a
very narrow wavelength - just white with none of the other colors mixed
in.

Adding an amber or green - or both? LEDs to the mix might make a more
comfortable "white".

YMMV

Just get a Color Kinetics controller and a RGB fixture and you can
choose one of 20 million different colors.

FWIW I have a headlamp that is switchable between blue-white and red
LED's. The red are much easier to use at night as they increase
contrast in the view. The blue-white is kind of a wash.

While we're on this subject, anybody have any experience with these:
