Where can I find artificial glowing colorful Christmas tree?

I'm looking for a mini artificial Christmas tree. One that is between 1' to 2' in height and 1' in diameter at the bottom. They are electrically powered white artificial trees. The "leaves" are white needles but they glow in beautiful colors especially at the tips. Where can I find one and what are they called officially? Thanks!|||fiber optic trees they are so pretty I wish I had them I saw them on qvc you might want to check their website|||i've seen those at menards, lowes and target. they are fiber-optic call around :]
