Using halogen and LED lights in your range hood are not recommended, and it is often not possible. You should instead stick to what the range hood manufacturer or owner’s manual says. Some range hoods have drivers or transformers to reduce the flow of electricity. Drivers are used for LED bulbs, while transformers are used for halogen bulbs. If you want to switch from halogen to LED or LED to halogen, you’ll need to switch from a transformer to an LED driver or vice versa.
