What affects a halogen bulb's wattage
A halogen bulb is rated around 50 W, but the real figure shifts with a few things:
- Model and rating: A halogen bulb ranges from about 35 W on efficient units to 90 W on larger or older ones — a spread of ~55 W.
- Usage: the real draw depends on the bulb type and brightness.
- Run time: because a halogen bulb typically runs about 4 h/day, hours of use matter as much as raw wattage on your bill.
