FREQUENTLY ASKED QUESTIONS

About the bulb

How does it work?

The driver in the base of the SWITCH light bulb delivers power to the LED chips, which are mounted inside the glass globe. As with all LED bulbs, this system generates heat. However, LEDs need to be kept cool to operate properly and have a long life – which is why SWITCH has developed a patented liquid cooling system to disperse the heat, keeping the LED chips cool and the bulb shining brightly and consistently. The liquid cools the LEDs by natural convection, moving heat out to the glass globe. The aluminum base, or heat sink, contributes by keeping the driver cool, as well as additional cooling of the LEDs. For more information, see “LQD Cooling System” below.

How is it different from an incandescent light bulb?

SWITCH LED bulbs deliver the same warm glow as incandescent bulbs, but they last longer and perform better. In comparison to an incandescent bulb, which lasts approximately 1,000 hours, these bulbs last at least 25,000 hours apiece. SWITCH LED bulbs use up to 80% less energy than incandescent and can save at least $130 in energy costs over the lifetime of each bulb. The SWITCH bulb is also made of materials that are reclaimable or recyclable.

How is it different from a Compact Fluorescent Light (CFL)?

Unlike many CFLs, SWITCH LED bulbs produce warm, incandescent-quality light that is evenly dispersed – not harsh or blue in color as it is with some fluorescents. The bulbs turn on instantly so light is available when it’s needed, not seconds or minutes later.

SWITCH bulbs are compatible with most dimmers, allowing the intensity of light to be varied without noise or flicker. One thing that a CFL has and a SWITCH LED bulb does not is Mercury – SWITCH LED bulbs pose no threat of toxic harm if they accidentally break.

It can be used in colder weather outdoors, unlike a compact fluorescent.

How energy efficient is it?

LEDs are the way to go for saving energy. The SWITCH bulb uses up to 80% less energy than an incandescent bulb to produce the same or better quality of light. For example, a clear SWITCH60 uses 12 watts compared to a 60 watt incandescent.

What is the LQD Cooling System?

SWITCH’s advanced LQD Cooling System™ is an innovative blend of two proprietary technologies: a cooling liquid that bathes the LEDs inside the bulb, and a patented driver that is both reliable and highly efficient. The overall electronic design works to cool the LEDs, using the bulb’s entire surface to disperse heat. As a result, SWITCH LED bulbs offer up to 40% better thermal performance than air-cooled LED bulbs. Better thermal performance means the SWITCH LED bulbs can be used in any fixture, even fully enclosed or recessed, and in any orientation without compromising light output or life.

The LQD Cooling System uses a liquid silicone, a coolant commonly used across many industries, and it’s proven to work. It’s an ingredient in food products and cosmetics, as well as for cooling large machinery and power plant equipment. Our liquid silicone is a benign, food-grade liquid, and is electrically non-conductive, non-toxic, and non-staining. It doesn’t degrade the LEDs or bulb components in any way, and it doesn’t harm people or the environment.

Safe for people, great for cooling LEDs—the LQD Cooling System has earned SWITCH LED bulbs the distinction of being the first liquid-cooled lighting product to be UL-approved.

What type of current does it use?

The LEDs within in the SWITCH bulb are driven by DC power. However, the bulbs work off of AC as the electronics inside make the conversion.

Is the globe glass or plastic?

Our globe is made of durable, thick glass created to withstand rough conditions and breakage. It passes the required “UL drop impact test” for LED bulbs, which is a minimum drop of 3 feet onto a hardwood floor.

What are Lumens?

Lumens are a scientific measure of the total amount of light emitted by a light source, such as a bulb.

What is the Lumen output for your 40, 60, 75 and 100 watt equivalent bulbs?

The 40 watt-equivalent SWITCH40 produces 450 lumens of light.
The 60 watt-equivalent SWITCH60 produces 800 lumens of light.
The 75 watt-equivalent SWITCH75 produces 1,100 lumens of light.
The 100 watt-equivalent SWITCH100 produces 1600 lumens of light.

What is the color temperature?

The color temperature, rated in Kelvin is:
SWITCH40– 2700K
SWITCH60 – 2700K
SWITCH75 – 2700K
SWITCH100 – 4100K

What is the CRI?

The CRI (Color Rendering Index) is a measure of the ability of a light source to reproduce colors accurately, as compared to natural light. All current SWITCH LED bulbs deliver warm white light, with a CRI of >80, which is a universally acceptable standard.

How long does it last?

The SWITCH bulb specifies an average lifecycle of 25,000 hours, which, with the average residential usage, will last over 22 years.

How do you calculate the lifespan of 25,000 hours?

No guesswork here – the SWITCH LED bulb’s lifespan is very carefully measured and calculated according to common standards developed by the Energy Star program and professional lighting engineering organizations. The standard for the test methodology is called IES LM80. We perform our testing using nationally certified testing laboratories so we can be confident in our results.

What brand of LEDs does it use?

SWITCH’s self-cooling technology is not dependent on a particular manufacturer’s LED chip, which means that SWITCH can continue to use the highest quality LEDs available.

What kind of testing has your bulb gone through?

We have completed testing for product safety, optical performance, lifetime, and reliability.

SWITCH LED bulbs are approved for use under “UL Listed for Damp Locations”, and conform to FCC CFR 47 Part 15 requirements.

We have also completed the full range of photometric testing (light performance) under IES – LM79 at independent test labs.

What is the warranty?

We stand firmly behind the integrity of our bulbs.

We offer a 3-year warranty on all of our products to the commercial user and a lifetime warranty for residential use.

Using the bulb

May it be used in all lighting fixtures?

We have tested this weight and it is acceptable in the vast majority of fixtures, including ceiling surface or flush mounted as well as recessed lighting. At approximately 10 ounces, it weighs less than a standard halogen PAR38 bulb.

How long does it take to install it?

As fast as you can unscrew your old incandescent or CFL bulb, you can screw a SWITCH bulb in. Some things just don’t change.

What bases can I use?

Our bulbs are compatible with any standard medium base E26 socket that an incandescent or compact fluorescent uses.

Will it fit in a short glass globe (where a conventional bulb will fit but ordinary CFLs are too long)?

The SWITCH40 and SWITCH60 bulbs are designed to be a direct replacement for the A19 incandescent, so wherever you currently use an incandescent, these SWITCH LED bulbs will fit.

Depending on the size of your glass globe, these bulbs may fit – or they may be just a touch too long because the fixture was designed for a smaller bulb. Please see our data sheets on our web site for more details.

When would you use a clear versus a frosted bulb?

It’s up to you which SWITCH LED bulbs you choose, but here are a few things to consider: Frosted light bulbs produce a more diffuse and softer light. You may want to use a frosted light bulb in the family room, bedroom and dining room – the places where you want a soft, flattering look, and in fixtures that do not already have diffused lens or other material in front of the bulb.

A clear light bulb may be used when a fixture already has a diffused lens, or another material in front of the bulb. Also, the clear versions of SWITCH LED bulbs have a striking appearance and style that may be preferred in some types of applications, both indoors and outdoors.

What ambient temperature can it be used in?

The recommended ambient temperature for using a SWITCH LED bulb is -20°C ( - 4°F) to 45°C ( 113°F ).

May I use SWITCH bulbs in damp locations, such as bathrooms?

Our bulbs are approved for use under “UL Listed for Damp Locations”. SWITCH LED bulbs are designed to work indoors or outdoors in applications that require a damp use listing.

May I use it outdoors?

SWITCH light bulbs make a beautiful addition to any indoor space, but they may be used in some outdoor applications as well.

They are constructed of durable materials, designed to withstand damp conditions, and intended to operate between -20°C (- 4°F) and 45°C (113°F).

May I use it upside down in my lighting fixtures?

SWITCH light bulbs are designed to work in any orientation, and in any properly installed lighting fixture.

Is bulb life the same in a horizontal orientation?

SWITCH LED bulbs are designed to perform flawlessly in any orientation. It may be used in an upright position, horizontally and upside down – and it works equally well in all of them.

May I use a 75W SWITCH LED bulb in a 60W lamp or fixture?

Lighting fixtures have a maximum rated wattage limit. SWITCH LED bulbs are designed to be direct replacements for incandescent light bulbs; however, it is important to follow the wattage limits noted on the fixture.

May I use your bulb in a recessed lighting fixture (enclosed)?

Yes. Unlike most LED A type bulbs, SWITCH products may be used in enclosed light fixtures and recessed lighting. To maintain great light quality and performance from our bulb, we recommend using it in a recessed lighting fixture of at least 6” in diameter, and maintaining a room temperature under 90°F/32°C.

What dimmers may I use it with?

We are also compatible with most dimmers. A list of recommended dimmers is available on our website.

May I use it outside of the United States?

Wherever there is 120V power, SWITCH LED bulbs can light up. Places such as Mexico, Canada and the US are equipped for our bulbs.

In the future, we will be able to address all voltages worldwide, including 100V and 220V/240V countries.

What about freezing temps for the liquid? Would the fluid expand in freezing temps to cause the bulb to break?

Unlike water, the fluid in our bulb remains pourable at -55°C (-67°F). No need to worry about expansion and breakage under normal cold conditions. The operating temperature range is between -20°C (- 4°F) and 45°C (113°F) ambient.

Does it get hot?

Our bulb heats up, but not as hot as an incandescent, thanks to our proprietary liquid cooling technology. An incandescent can exceed 160°C (320°F), but the SWITCH light bulb exterior can heat up to between 80°C and 90°C (176°F and 190°F), so make sure to let it cool down before touching it. This means that we are getting heat away from the LEDs and other electronic components.

Radio frequency interference is a problem with the CFL low wattage lights. Do these SWITCH lights cause RFI?

No interference with SWITCH LED bulbs. Our lamps pass the US governments Federal Communications Commission (FCC) requirements for electrical emissions; both conducted and radiated FCC 47 CFR Part 15.

My bulb broke, how do I clean it up?

We’re sorry to hear that your bulb broke! Not to worry – the liquid inside is non-toxic and non-staining. It can be wiped up with a soapy sponge or damp cloth.

If it breaks, may I put the pieces into the trash?

SWITCH uses materials that may be recycled. Check with your local waste management / recycling center for local guidelines on handling electronic waste.
