Question:What is a “moving flame” flameless LED candle, and how is it different
than a “non-moving flame” flameless LED candle?
Answer:The basic difference between “moving flame”
and “non-moving flame” flameless LED candles is the “moving flame” candles have
an actual candle flame-like element that physically moves from side-to-side.
“Non-moving flame” flameless LED candles do
not have anything that physically moves, but rather they have one or more LEDs
that vary in brightness in an attempt to simulate the action of a real candle flame.
Since real candle flames physically move and
vary in brightness, “moving flame” flameless LED candles produce the most realistic

flame” flameless LED candles work, see our “
CANDLE EDUCATION” section.
the advantages and disadvantages of flameless LED candles vs. real candles?
Answer:The advantages of flameless LED candles over real
candles are numerous, and there are very few disadvantages.
Below is a long list of advantages and a very
short list of disadvantages.
Advantages of Flameless LED
There is no fear of catching
anything on fire.
They don’t generate heat.
They don’t melt the candle wax,
so the candle will last a “lifetime”.
There is no melting wax that
drips all over the place.
They don’t burn out.
They can tolerate windy
You can turn them on and off
with either a hand-held remote control (if remote capable) or a timer.
They can be used around pets.
They can be used around elderly
folks and children.
They can be decorated (cuff,
sleeves, wraps, adornments, coatings, decals, impressions, etc.).
They can be placed virtually
anywhere without the worry or risks associated with real candles.
They are great for plays,
musicals, stage sets, parties, weddings, etc. without the worry or risks
associated with real candles.
They don’t emit smoke or fumes.
They can be used over and over.
A one-time investment that will
last many years.
They are a great conversation
They make great gifts.
Disadvantages of Flameless
They use batteries (but they
don’t melt and can be used over and over!).
They don’t have real flames
(but real flames can catch things on fire!).
does the LED color seem to vary from candle to candle?
Answer: Different manufacturers of flameless LED
candles may use different types of LEDs.
The color temperature of a light source is rated by something referred
to as the “color temperature”.
diagram below illustrates the different color temperatures for light
Most LEDs used in flameless LED
applications have color temperatures that are on the “warmer” side (left side) of
the diagram such as 2,500K or lower.
addition to LED differences from manufacturer to manufacturer, there may also
be slight differences in color temperature between different production batches
of the same LED.
For example, a
manufacturer of the LED, which is supplied to the flameless candle
manufacturer, may run a production batch of 1,000,000 LEDs, and they will all
have almost exactly the same color temperature due to very minor differences in
the production process; however, the next batch of 1,000,000 LEDs run a month
or so later may have a more noticeable difference in color temperature than the
previous batch which can result in visually noticeable differences in color
manufacturers and LED manufacturers attempt to try and keep these color
temperature variations to a minimum, but nothing is perfect.
Question: How long will the LED last in a flameless LED
Answer: The LEDs used in flameless LED candles consume
very little power when compared to the LEDs used in light bulbs for general
LEDs are unlike
traditional filament bulbs in the sense that they have a semiconductor die (see
below) instead of a wire filament.
is typically the mechanism behind both wire filament bulb failure and LED
Since the LEDs used in
flameless candles don’t get very hot, they typically don’t suddenly fail due to
heat, but instead, their brightness will slowly decline over time.
The useful life of an LED is typically
defined as the time it takes for the brightness to decline by 70% from its
The useful life of
an LED used in a flameless candle can exceed 100,000 hours which would equate
to over 11 years if the LED were left on 24 hours per day.
Even then, the brightness would only decline
by approximately 70%.
For this reason,
the LEDs used in flameless candles are specified to last a “lifetime” for all
I believe Luminara makes the best flameless LED candles because they have the best
moving flame action, but I am considering purchasing a non-Luminara flameless
Is the moving flame action
just as g ood on some of these non-Luminara flameless LED candles?
Answer:The video below allows you to compare the moving
flame action of our TLV series of rechargeable votives with the Luminara moving
The TLV series of
rechargeable votives are made exclusively for LightsandBatteries.com.
Notice that the moving flame actions are very
The TLV votive has a unique
translucent glow to it while the Luminara votive is opaque.
Also, the LED lighting on the actual flame of
the TLV votive is more diffused than it is for the Luminara votive. There is no question that Luminara is the most recognized brand name of moving flame LED candles on the market, but other brand names such as Avalon, Torchier, Liown and Mystique all have very similar moving flame actions. In fact, Avalon, Torchier and Liown have almost identical moving flame actions when compared to Luminara, and you would be hard-pressed to tell the difference. The Mystique brand name is slightly different in the sense that the moving flame action randomly flickers from a very calm flame to a more active flame, so you will see some differences with this brand name when compared to Luminara. Which one is the "best" is simply a matter of opinion. See our discussion in the
"CANDLE EDUCATION" section for more details on the differences between the various brand names and how they are related.
Question:What kind of wax
is used to make flameless LED candles?
Is it the same kind of wax used to make traditional flame candles?
Answer: Most of our indoor flameless LED candles are
made of real paraffin wax, and yes, it is the same kind of wax that is used in
real, traditional flame candles.
Paraffin wax is a white or colorless soft solid derivable from
petroleum, coal or oil shale.
at room temperatures and begins to melt above approximately 115
-degrees Fahrenheit (its boiling point), and
it contracts quite a bit as it gets cooler (below room temperature)
these reasons, indoor flameless LED candles made of paraffin wax should not be
exposed to high temperatures, direct sunlight or freezing temperatures.
If they are exposed to freezing temperatures,
the candle may actually develop small hairline cracks due to contraction of the paraffin wax
. Common applications
for paraffin wax include lubrications, electrical insulation and candles.
Some of the smaller tealight and votive
candles in addition to our outdoor candles are made of an ABS plastic material
instead of paraffin wax.
We carry a wide
selection of paraffin wax indoor candles that are available in various scents
like vanilla, cinnamon, pine, etc.
our indoor paraffin wax candles are unscented for those who have allergies, are
sensitive to odors, or those who simply prefer not to have scented candles.
Question:What kind of water should I use in my
flameless LED candle fountain (for example, the aquaflames)?
Answer: We recommend using distilled water or water
purified from a reverse osmosis purification system since it will not contain
any phosphates, nitrates, chemicals or heavy metals which can cause an
undesirable buildup of “gunk” and/or algae growth in the candle and pump
mechanism resulting in reduced water flow.
If left unchecked, the water may become cloudy and disgustingly dirty,
and the pump may completely stop pumping water.
If regular tap water is used, we recommend adding a few drops of liquid
bleach to the water to prevent algae growth.
If algae growth does occur in the candle, then we recommend filling the
candle up with fairly hot water and shaking it around until the inner surfaces
of the candle are clean and free of algae and “gunk”.
Also, to reduce the chances of algae growth,
keep the candle out of direct sunlight.
Question:My flameless LED
candle fountain (for example, the aquaflames) has stopped pumping water.
What might be the problem?
Answer:This problem might occur for several
First, is the candle plugged
in, or are the batteries dead (if using batteries)?
Second, make sure there is enough water in
the candle since most candle fountains will automatically turn the pump off to
prevent dry running of the pump which might result in damage.
And, the last problem might be caused by
using regular tap water in the candle.

Question: The water in my
flameless candle fountain is really loud (for example, the aquaflames).
What can I do?
Answer: This can be caused by a low water level in
the candle fountain which means you basically have a tall waterfall in the
candle, so the water that is pumped to the top of the candle has a longer
distance to fall before hitting the pool of water in the bottom of the candle.
Running the candle at higher water levels
will result in quieter operation.
is basically a personal preference, so experiment with water levels until you
find a level that is comfortable for you.
Question: How long will rechargeable candles last
since they run on internal rechargeable batteries which have limited life spans?
Answer: All of our rechargeable
candles have lithium-ion (Li-Ion) batteries, so they will have a limited useful
service, life just like all rechargeable batteries, due to chemical changes in
the electrode which results in reduced storage capacity.
The advantages of Li-Ion batteries over other
battery chemistries such as Nickel-Metal Hydride (NiMH) is they have very low
self-discharge rates, high energy densities and no required charge/discharge
cycling to reduce the effects of memory.
The useful service life of a Li-Ion battery is specified as “Battery
capacity decreases over time due to chemical changes in the battery’s electrode
as a result of the number of full charge/discharge cycles, and the capacity
loss is usually specified as a percentage of its initial capacity.
A Li-Ion battery’s useful service life is
typically specified as a 30% loss of initial capacity after a specified number
of full charge/discharge cycles since this is the primary contributor to a
battery’s capacity loss.
For example, if
the Li-Ion battery in a candle is specified to have a useful service life of
approximately 500 charge/discharge cycles, then one can expect the candle burn
time to decrease by 30% of its initial value after the candle has been fully
charged and discharged 500 times.
a candle has an initial burn time of 10-hours, then this burn time can be
expected to decrease to approximately 7-hours after being fully discharged and
discharged 500 times.
As one might
expect, this useful service life if far more complicated than just the number
of full charge/discharge cycles and also depends on other factors such as the
age of the battery, exposure to elevated temperatures, and the depth of each
discharge (was the battery completely discharged after being fully charged).
The Li-Ion battery in a rechargeable candle
usually doesn’t just stop working, but rather the burn time of the candle will
simply decrease to the point where it is no longer acceptable to the end
If a candle is fully charged and
discharged once per day, and Li-Ion battery is specified to have a useful
service life of approximately 500 charge/discharge cycles, then one can expect
to get approximately 3 or more years of service out of the candle before the
battery’s capacity has degraded to the point where it is no longer considered
acceptable for use in a typical application.
What is the best type of battery to use in my
flameless LED candles?
or Lithium batteries are recommended for use in all of our flameless LED candles.
We sell both types, and Lithium batteries will last longer than alkaline batteries, but they are slightly more expensive. Other types of batteries such as the older
Carbon Zinc (Zn/MnO
2), rechargeable Nickel-Cadmium (NiCd), and
rechargeable Nickel-Metal Hydride (NiMH) can be used, but the burn times may be
severely reduced from the burn-times specified on our website when using
If other battery
types are used, the flameless LED candles may not be as bright and may begin to
flicker after a short period of use.
Also, do not mix different battery chemistries like Alkaline, Carbon
Zinc and Nickel-Cadmium.
mixing Alkaline batteries with Carbon Zinc batteries can cause the Carbon Zinc
batteries to heat up more in operation causing them
to leak chemicals faster, and it can also drag down the Alkaline batteries
causing them to die faster.
Question:Is it okay to operate or store my flameless LED
candles in extreme temperatures?
Answer:There are several reasons to prevent exposing
flameless LED candles to extreme temperatures as summarized below. For these
reasons, it is recommended to operate and store flameless LED candles between
temperatures ranging from 45-degrees to 90-degrees Fahrenheit.
The paraffin wax used in the construction of indoor
flameless LED candles melts above approximately 115-degrees Fahrenheit
(its boiling point).
The paraffin wax used in the construction of indoor
flameless LED candles contracts as it gets cooler (below room temperature)
and may actually crack if exposed to freezing temperatures.
When non-rechargeable batteries (e.g., alkaline, carbon
zinc, etc.) are exposed to high temperatures for long periods of time,
they can begin leaking chemicals which can cause corrosion damage in the
candle’s battery compartment.
recommend using good quality alkaline batteries to reduce the risk of chemical
leakage in general.
When Li-Ion rechargeable batteries, such as those in
rechargeable flameless LED tealights and votives, are exposed to extremely
high temperatures, they can catch fire or even explode.
Batteries tend to self-discharge slowly which is why
they don’t last forever when just sitting around not powering anything,
and they will self-discharge at higher rates at higher temperatures.
Batteries tend not to work as well at lower temperatures,
so the LEDs in flameless LED candles may not be as bright, the flames may
not move around as much, and the battery run times may be reduced.
Question: What is the
difference between a “tealight” and a “votive” flameless LED candle?
Answer: The differences are
basically a matter of opinion when considering flameless LED candles, but
tealight candles are generally shorter in height than votive candles.
Tealights are typically less than 2-inches in
height, and votives typically range from 2.5-inches to 3.5-inches.
Tealights will fit nicely in the smaller
candle holders where the votives might be too tall resulting in the flame
protruding past the top of the holder.
Always measure the candle holder you wish to use, so you can select the
appropriate candle height (and diameter).
Question: Why are some of
your flameless LED candles not remote capable?
Answer: Remote capable candles contain additional
electronic receiver circuitry that adds cost to the candle, so we offer candles
that are no remote capable for those who do not require this function or for
people who prefer a lower price point.
We recommend remote capable candles for people who have a large number
of candles they wish to control or for candles that are in hard to reach
locations. The pictures below illustrate the additional electronic electronic receiver circuitry in a rechargeable tealight that is remote capable.
Question: What is the
difference between “indoor” and “outdoor” flameless LED candles?
Answer: Most of our indoor flameless LED candles are
made or real paraffin wax (with the exception of the smaller tealights and
votives which are made of ABS plastic) and run the risk of melting if exposed
to excessive heat or direct sunlight since the typical melting point of
paraffin wax is between
and 154 degrees Fahrenheit.
also possible for them to crack if exposed to freezing temperatures since
paraffin wax contracts quite a bit as it gets colder.
Outdoor flameless LED candles are made of ABS
plastic which prevents them from melting or cracking when exposed to
Outdoor candles are
also waterproof and have drain/slit holes in the bottom to prevent them from
filling up with water when exposed to rain.
Question: What will happen if I subject my flameless
LED candle to moisture or direct contact with water (rain)?
Answer: We carry both indoor and
outdoor flameless LED candle.
our indoor candles are made of real paraffin wax (with the exception of our smaller
tealights and votives which are made of ABS plastic), and our outdoor candles are
also made of ABS plastic.
candles are constructed to be waterproof and have drain holes in the bottom to
prevent the candle from filling up with water when subjected to rain.
Indoor candles are not constructed to be
waterproof and may fill up with water when subjected to rain.
Since indoor candles are not waterproof, they
may fail if subjected to rain or high levels of moisture that might be found
outside, in steam rooms, bathrooms, saunas, indoor pools, etc.
