One of the two I bought only lights half the LEDS - what might be wrong?

There may be an improper ground or a back feed in the hook up of the lights.

Sounds like you may have them wired into a two way switch (something that would turn on regular lights then when turned off, it sends the power to the LED lights). Its difficult to assist since I don't know how you wired them or where you spliced the hot (red) wire into.

it might be simple as (settings), you can try going to your settings and turn off the auto brightness and adjust the brightness to a full.or it can be a defected parts. always by an OEM parts for replacements.I don't think there is anything wrong with you motherboard.

One lights is fine. You can go to the web site of trulummen they have more detail info

The one in picture #3 is correct. There are holes in the heat sinks to get the hardware in. The first one I ordered only half of the LEDs worked, a replacement one was sent out and that one works fine.

Send in for a new one...really! Or you could try to fix it by buying new boards; it is not the back light or power supply.

If both lights up, u have it wired wrong. At that point, the remaining pin on the bulb is the ground pin. I suggest u get a multimeter to determine which wire is hi/low beams power and ground.

Mine does that the LED power meter, though it doesn't appear to light up at all. As the other person responded, is better to have the power meter icon in your system tray in lower right corner, easier to read, more informative, etc.

I've never had this problem. An LED should NEVER get any more than slightly warm unless something is wrong.

There must be a crack in the pc lines. They are set up in groups of 3 LEDs. Cut it where it's dead and apply power from other end. It prob got damaged. OR Talk to the seller. Some sellers will send a new strip/ spool

I actually did replace one of mine with an LED just to test it out and almost no light comes out of it. The LED lights just don't seem to put out enough light. :( I would love to find some LEDs that do though considering I am running like 15 of these all night long.

Its done, buy a new higher wattage one, add up the load of your LEDs and get an appropriate rated power supply

Mine did not come with led's just black plugs where they are suppose to be. I think they are reserved for the more expensive model.

I would ask the seller. These are LED lights so they can't just be replaced. If its new the unit may be bad. Sorry

Mine has 3 LEDs per side and a major difference between hi and low in nightlight mode. Yours could be defective.

Do you have those light switches with a light in the switch? That could be the problem. If so, try changing one the the switches to a non-lighted kind. And no, the LED's should go off all the way.

Sounds like internal wiring issue inside the lamp itself. Make sure your connection has good ground. I'd try powering the lights with a separate pwr source, if they still don't work return for warranty.
