From their designs, halogen mains voltage lamps can be categorized as single-ended and double-ended lamps. Depending on the application, they are designed to operate on 230V, 240V or 120V.The color temperature of the lamps varies according to the application: 3400K for maximum luminous efficacy, 3200K for professional film and TV work, 3000K or 2900K for applications where long life is important.
To prevent personal injury or damage to property, halogen lamps may only be operated in suitable luminairesdesigned with suitable mechanisms (protective shields, grids, etc.) to ensure that in the event of a lamp bursting no parts/shards can escape and that during operation no ultraviolet radiation can escape. There must also be a warning sign to indicate that the lamps give off high levels of heat.
