Product review (1 stars): Don't buy, cheap defective product
It is a manufacture defect. OMG, the expensive hood comes with 2 non-LED bulb. They are super hot. I guess it is 40Watt each. Interestingly, when I replaced them with LED GU10 bulb, the bulbs have never turned off. They are dim when I turn them off but there is no way to turn them off. Hopeless.
