Table lamps are designed to sit on tables. They are not floor lamps, which sit on the floor. Table lamps are usually shorter than floor lamps.

Fixing a defect halogen bulb/ How do I replace the bulb? For sunset l

Rather than buying a new sunset lamp, I would like to fix or replace this halogen bulb. Looks easy enough to remove it, just need to know how and where to find these bulbs , and if they can come presoldered (preferred)

@sammorgan this one does not have a halogen lamp. You are looking at an SMD LED. It is soldered to the board. Where does the light plug into? What you are looking for is actually something like this

and you can check it more information on it right here

Follow the advice given in the other answers on how to determine the proper voltage for this LED

@oldturkey03, nice find on the LED!

@sammorgan, You'll need to verify the voltage before buying these; the ones that appear to match yours take 3.0 to 3.3 VDC. Thanks to oldturkey03's URL, I also found some that take 6-7V, so you'll need to know in order to get the right part.

Hi Sam,

Okay, there's going to be some confusion here due to your wording.

A halogen bulb is an incandescent bulb filled with halogen gas. What you're looking at there is an LED bulb, which has no relation whatsoever to the word halogen. The 4R7 seen in the picture is just the value of the surface mount resistor that number is printed on.

We don't have much to go on here; for one thing we'll need to know the input voltage being fed to the LED through the red and black wires. I'm guessing it doesn't plug directly into the wall; is there a power adapter in that line somewhere? If so, what's the output voltage from it? AC or DC? That'll at least give us a start at figuring out what can be used as a replacement.

As far as your existing board, I'm a little suspicious of the connector to the left of the LED; it looks a little burnt to me. That may just be from age and heat depending on how old it it, or it could indicate a problem. What does the back side of that little circuit board look like? Can you get a picture of that?

Do you have a voltmeter? If so, it might help if you can measure the voltage across the red and black wires, along with the voltage present at the two pins of the LED itself.

Let us know what you find.
