First LED Experiment

Decided to try my first LED. On my Artic Fox there is a G4 halogen fixture right as you enter the camper controlled by a dimmer switch near the floor you can reach before you start climbing into the camper. I like to leave that light on as an "entrance" light when you first come in. While browsing a local marine supply house I came across a number of LED lights and replacement bulbs. One of the bulbs they had was a G4 replacement with 7 warm white LED's and three red LED's. The way it works is that when you forst turn it on the red LED's come on. If you turn it off and then on, the white LED's come on. it was a bit pricy,$24, but I decided to give it a try.

It works pretty well. The pictures I took don't show the true difference in brightness (the whites are considerably brighter than the reds but they do give you some idea). Here are the red LED's:





And here are the whites:





I will be leaving the red on as a "night" light and use the white when we want light. The only downside is that the white only dim some and the red do not seem to dim at all. Overall I am pleased.

Off topic. I thought RV's were expensive to own. Browsing through the marine store I realize how cheap things are compared to boats.

  • The red light is traditionally used on boats to preserve night vision. There have been objective tests on the subject, which prove that the color red has nothing to do with it, it is simply the reduction in brightness. But red lives on due to tradition.

    I tied a couple of different LED replacement bulbs and found one that I like. There are some pretty big differences between bulbs that are described and spec'ed similarly, I encourage everyone (given the cost) to order one to begin with and see if you like it. The ones I ended up with have a little whiter color temperature than the incandescents they replaced and are at least as bright, but consume a bit less than 25% of the power.
  • I think the orange lenses are to keep from drawing as many bugs. Red is supossed to be easier on the eyes at night. Look at the cockpit lights on some aircraft.
  • Is the red light so as not to ruin your night vision? (I've seen those submarine movies). Is that why the outside lights are often orange?

    Steve.
  • I didn't even bother experimenting with LEDs. I changed everything out to them when I rebuilt my camper. I didn't want the high current draw that you get from incandescent bulbs. By the way, $24 wasn't a bad price for the bulb. I imagine that the LEDs will go down in price as time goes on.
  • I agree. Red light makes for a great night light. I have two puck lights over the dinette area that go red when they're turned off. They're red all the time, but they consume so little power I don't worry about it. They remind me of my Navy days at sea.
  • Im suprised your getting any response using a std dimmer switch, least thats what Ive alwasy heard, never tried though. They do make led specific dimmers-Unlike an incandesent bulb, cutting the power doenst usually have much if any effect on led until it goes off. LED dimmers turn power on/off rapidily givng effect of 'dimming'. Heres some info-theres better info, this was 1st that popped up link
    Kinda like the red-more submarine than marine though.
