Halogen bulbs emit a much crisper, cleaner white light than incandescent bulbs and are much more efficient. Many people switch to halogen bulbs because of the effects they can create - they can make the room or objects they are illuminating more vibrant and attractive to the eye, and colours appear more invigorating. They are most commonly used around the home, in fashion shops, jewellery shops, hotels, and shops selling high value, high quality products.
