VARILIGHT dimmer switches have an industry-wide reputation for exceptional performance, long life and innovation at attractive prices. All our dimmer switches are designed to meet the latest European Safety Legislation. Our standard dimmer switches can be used for mains incandescent GLS lamps (standard mains light bulbs). They can also dim GU10 or similar Hi Spot Mains Halogen lamps. Each dimmer specifies its maximum load so simply match it to your requirements. By using standard dimmers there is a zero risk of damage in case of lamp failure and a dramatically improved lamp life.
