The Finally Light Bulb Company

Frequently Asked Questions


Are Finally Light Bulbs dimmable?  Finally Light Bulbs will eventually be offered in a wide range of designs, lumens (or Watt equivalents) and styles, including dimmable and non-dimmable. Our 60 Watt and 100 Watt Replacement Acandescent Light Bulbs are not dimmable.  However, Acandescent technology can be dimmed and we look forward to offering dimmable light bulbs in many replacement wattages soon.

Enclosed Fixtures

Can Finally Light Bulbs be used in enclosed and/or recessed lighting fixtures?  Our 60 Watt Replacement Acandescent Light Bulbs are approved for use in enclosed and recessed lighting fixtures.  Our 100 Watt Replacement Acandescent Light Bulbs are not rated for use in enclosed fixtures but may safely be used in recessed lighting fixtures.

Energy Star

Are Finally Light Bulbs ENERGY STAR certified?  We are in the process of obtaining ENERGY STAR certification.


Do Finally Light Bulbs produce heat? Our Finally Light Bulbs emit no more heat than a standard LED of similar wattage and a LOT less than a traditional incandescent.


Do Finally Light Bulbs last as long as LEDs?  LED technology is not uniform.  When it comes to LED light bulbs, longevity, efficiency and light quality vary deeply from brand to brand and style to style.  You never know what you’re going to get. Our 60 Watt and 100 Watt Replacement Acandescent Light Bulbs are rated to last 15,000 hours – that’s 15 times longer than a traditional incandescent – or least 13.7 years if used three hours a day – which is how the Federal Trade Commission asks us to measure longevity.


Do Finally Light Bulbs contain mercury?  Yes, less than 2 mg in solid form (amalgam.)  Please read more about mercury here.

Outdoor Use

Can Finally Light Bulbs be used outdoors?  Our Finally Light Bulbs can be used in outdoor fixtures, like a coach light, as long as they are shielded from direct contact with rain or snow.  We are proud to report that the light output of our Finally Light Bulbs is not influenced by ambient temperature.  They will start in the range of 0°F to 122°F (-18°C to 50°C), though sustained operation at or above these extremes is not recommended.


Do Finally Light Bulbs cause any Radio Frequency Interference?  Our lamps are designed to meet the relevant limits for residential use set by the FCC.  They are tested for both conducted and radiated emissions as required by Part 18 of the FCC regulations.

UL Certification

Is the Finally Light Bulb UL certified?  Yes, Finally Light Bulbs are UL certified. UL (Underwriters Laboratories) is a safety consulting and certification company established in 1894.  Its product certification programs are accredited by the U.S. Occupational Safety & Health Administration (OSHA), the American National Standards Institute (ANSI), and the Standards Council of Canada (SCC).
