I bought this hood because another model was not available.  This model is higher in price, and does have an Energy Star rating and LED lights.  It lacks some features on a lower priced model such as more fan speeds and a timer on the fan.  This is a decent vent hood and provides a lot of bright light on the range top.  The LED lights don't project heat like the halogen bulbs would have.  The fan is quiet on the low speed but a bit loud on the high speed.  I use it in recirculate mode so I don't use the fan much at all.  Overall, it's a decent vent hood but at this higher price point could have included more features.
