Halogen spot bulbs produce a bright warm light and they are fully compatible with dimmer switches.
This bulb is larger than your standard GU10 bulb as it is 63mm across. It is also brighter and uses more power (75w) and therefore is in no way low energy. It is regarded as a 'flood' bulb with a 38 degree beam of light.
This current batch from Schiefer Lighting is in plain white marked packaging.
