    Bulb Information

    LED bulbs do not go out immediately when turned off. They slowly fade when the door switch is pressed. This is normal.

    • Longevity will vary based on how often the doors are opened and for how long per opening. Blue glass light bulbs have a life expectancy of 1000 hours.

    Other bulbs available in stores will fit Sub-Zero products, but the light color will not match.

    • Alternate bulbs need a T10, medium base, 40W appliance bulb.
    • Standard 40W appliance bulbs that fit these specifications tend to be yellowish.
    • Standard appliance bulbs are available in local hardware or home improvement stores.
