can a outdoor lighting be converted to led lighting?

i have a low voltage outdoor lighting and its not bright enough i want to convert it to use leds can it be done

I got my pulsing to stop with my LED replacements by leaving just one halogen bulb in a socket.

Based on what I've read here, I'll try replacing it, and swapping polarity on a couple LED bulbs.

The answer truly is yes, and no. Yes, you can put them in, and it may work, but you will likely run into issues if the LED's are not designed for outdoor lighting. Here's why. LEDs are diodes which force current to go a single direction. Most all outdoor lighting is alternating current. They us AC to help reduce the effects of corrosion due to galvanic reaction from moisture, and metals and minerals in the earth. When you introduce the LED you are now forcing the current in a single direction. The LEDs will light up, but the galvanic process will eventually corrode the terminals between the primary wire feed and the housing.

The other issue you may run into is pulsing. If you get enough LEDs pointing the same direction it will force more current to go one direction then the other causing the AC transformer to give a surge effect. If you choose to convert to DC entirely, you may run into a distance issue. When you push electrons over longer distances in a single direction, you have more resistance to consider, as all of the electrons now need to travel the entire loop. This too can give you an odd and intermittent surging effect to your lights.

Unfortunately, I've tried all this and learned the hard way, but I've learned alot doing it. Fortunately, you can learn from my mistakes :). There are some workarounds. You can try swapping the LEDs so that every other one is going a different direction, but then you still have the galvanic reaction concerns. You can place a resistor at each LED placement, but then you lose the cost savings you would get from the LED. Your best bet is to double up the LEDs so that the polarity is reversed and one LED will allow current one direction and the other will allow equal flow the other direction, thus preserving the AC nature it was originally intended for. Rather than soldering a bunch in a custom configuration, I'm searching for a housing that can take one bulb socket and branch into two. Then you can do this without any hassles of soldering and buy the cheap automotive LEDs for replacement.
what the lights applications?

You certainly can convert your low voltage lighting to outdoor LED lighting. Since low voltage lighting uses 24 volts or less you can simply swap the existing bulb for an LED equivalent bulb.

LED lights have a high resistance to moisture which prevents them from shorting out in places where water would normally accumulate. Although LED lights are very moisture resistant, the electronic circuitry surrounding them is not so resistant.

That's why its important that the lighting fixture's housing (which the LED bulb fits into) is water and moisture resistant.

Yes.

Most low voltage outdoor lighting is 12 or 24v. I'm gonna assume 12v.

With 12 volts you can hook up a LOT of led solutions, and since you want BRIGHT, I would recommend going with pre-packaged solutions, bulbs designed for 12 volts.

I REALLY like all the stuff I've gotten from dealextreme. I don't get anything for saying this, but http://www.dx.com has lots of leds. If you just search 12v led you'll get tonnes. Find something that will fit in your light housings and make it go! (then make an instructable about it) For heat considerations you probably don't want to exceed 3 watts unless you're going to add more cooling. 3 watts of LED is a LOT of light.
What kind of lighting? How may volts?

Any lighting system can be upgraded to LEDs. it just a matter of getting the correct back end that will take the input voltage and make it safely drive the LEDs.
