Halogen to LED

Other than he physical size issues are there any electrical concerns with switching from halogen interior cabin lights to LED lights? Can I just pull out the halogens and rewire in the LEDs? I'm thinking it would save a load on power demands.

Re: Halogen to LED

Why not just keep the fixture and replace the Halogen bulb with an LED equivalent?

Re: Halogen to LED

That's what I am thinking, but I am questioning if there will be any issues with the change in amp load that I have to be concerned about.

Re: Halogen to LED

There shouldn't evany problems with the load if it going down (smaller load). We replaced all of the halogen and incadescents with LED replacements. Overall not as bright, but the lower draw (1/10th of previous) is worth it. Be sure to get WARM color LEDs. They don't have that cool electric blue hue which is odd and unnatural.

Re: Halogen to LED

Your halogens are presumable 12v 20w .... 1.66 amp each. No way your LEDs will exceed that.

Re: Halogen to LED

One nice advantage to LED's, they don't put out the heat of a Halogen. Much cooler to the touch.

True but don't kid yourself that they don't produce heat. The best LEDs for mains voltage usage have whacking great heat sinks to disperse some of that heat. One of the major causes of LED individual diode failure is overheating.

In a boat this is probably not an issue unless the LED lightsource is in too tight an enclosure.

Re: Halogen to LED

I replaced a bunch of festoon bulbs with their LED equivalent. Just for the heck of it, I pulled out my little temp gun I keep on the boat. The regular festoon bulbs were in the 150-160 degree range. All my LED's were less than 90 degrees.

Re: Halogen to LED

Replaced every one of our interior bulbs with Marinebeam LED replacements. Way fewer amps being used and less heat being generated--can't find a worry in that.

I have an LED flashlight that gets warm to touch if it is on for a couple of minutes
