Edit. Not a very good pic, but here's my tree this year. It's got some really cool lights I found at Target. They are red, green, and pearly white little bulbs. I just love the effect. Can't get the picture to work. I give up.
Funny enough, we actually had a fake tree growing up. I always thought it was the best tree ever until we did a fresh cut noble fir 10 years later.
IIRC the solid ones had a reflector at the base to keep the heat away from other sources.
