CTKcom MR11 12 Volt 10 Watt Halogen Light Bulbs,30 Degree Beam Spread Precision Halogen Reflector Fiber Optic Light Bulb with Glass Cover,6 Pack

I gave up trying to use this product after 3 of the 6 bulbs failed. Got onto Amazon to request a REFUND, since I found the bulb I needed at a local store -- and they processed my request as a REPLACEMENT. I don't know who I"m more annoyed with: the vendor, or Amazon. What a nightmare.

This is a great price for these bulbs, but none of them have lasted longer than a few months. I bought them about 14 months ago and the 3rd one just burnt out. That works out to a little over 4 months per bulb, and that's if I put one in the range hood on the day I bought them, which I most likely didn't. There are 2 lights in the range hood. The bulb in the other light fixture has lasted through all 3 of these bulbs and then some. Maybe I got a faulty batch. It's a shame because this really is a great price for these bulbs.

I could not find these bulbs anywhere except on Amazon. I received and install 3 of them in my lights and they work just fine. It has been several weeks and they are still working. The quality is good.

I have a hummingbird fiber optic lamp that these bulbs work wonderfully in! They last forever, it seems . . . depending on use, of course. Very happy with these bulbs!

The light was correct with the correct number but the plug in prongs were to short would not turn on they are half the size of the original ones

Easy to install and direct replacement. Much cheaper than OEM part. Great for the DIY project.

These are very handy lights and bring out the beauty of the Christmas trees with the fiber optics in/on the tree. Makes them very beautiful. The trees that is.

It bulb was put in an old optic tube light sculpture light. It works like new. We are amazed at how bright the colors light up with the new bulb

Solved my problem
