The JOI Lamp transforms candle heat into LED light!
JOI uses the same thermoelectric technology as our Ecofans to transform the energy of a tea light candle into enough light to illuminate your night. Within minutes, JOI begins to convert the heat of the candle into more than 100 times the light generated by the tea light alone.
Designed to be a contemporary centerpiece with style that appeals to all, JOI offers a unique and useful light source indoors and out.

Frequently asked questions.
How does JOI work?
JOI uses thermoelectric technology to convert a temperature difference into electricity. At the center of JOI is a unique thermoelectric module. The patented JOI design activates its LED lights by creating a hot side and a cold side on the module and when this happens a principle called the “Seebeck Effect” causes electrons to flow within the module.
My JOI seems to be brighter when I use it outdoors. Is that possible?
Yes, the cooler, moving air outdoors allows JOI to operate optimally.
Can I use my JOI indoors?
JOI is designed and tested for outdoor use. However, third party fire safety engineers have examined JOI and found it much safer than burning an open candle inside a home and safe for use indoors when the operating instructions are followed.
The candle won’t stay lit when the door is closed. What can I do?
JOI requires draft airflow to be created in order to work properly. Allow the candle to burn for at least 45 seconds but not more than 60 seconds before closing and latching the door.
Condensation is forming on the inside of the glass. What can I do?
Water condenses on the cold glass until it warms up. Allow candle to continue burning and condensation will disappear.
I heard a loud snap and my JOI snuffed out. What do I do?
Your candle has been burning abnormally and has activated the JOI safety feature. Wait approx. 4-5 minutes until you hear an additional snap as the safety feature resets. Change the candle, clean any soot buildup and relight according to instructions.
The lights aren’t as bright as normal. What can I do?
This could be a result of soot build-up on the heat collector. Clean heat collector as shown in the manual.
I’m using a smaller 2 hour tea light and the lights aren’t as bright as normal.
For optimum results use only 5/8” (16mm), 4 hour tea light candles.
Soot or smoke can be seen rising out of the top of JOI. How can I prevent this?
A.Your candle wick is likely too long. Trim candle wick to ¼” (6 mm) length.
B.Candle wick is not in center of heat collector. Replace candle with one that has wick standing upright in the center of the candle.
My JOI was left in the rain and now the candle won’t stay lit. Is it ok?
Excessive moisture has found its way into JOI. Allow the candle to burn in the candle holder cradle with the door open for 3 minutes before closing and latching the door.
How do I clean my JOI?
A) Allow JOI to cool completely.
B) Place JOI on top of newspaper and wear gloves. (soot is very messy)
C) Open door.
D) Insert paper towel below heat collector to catch any falling soot.
E) Remove heat collector shield by pulling straight out.
F) Remove soot by running a folded piece of paper or clean paint brush through the grooves of the heat collector.
G) Carefully remove the sooted paper towel.
H) Replace heat collector shield and close door.
How do I replace the Heat booster if it has come loose?
The Heat booster may have come loose during shipping. If the heat booster has come loose it must be put back on for JOI to work optimally.
I can’t get my JOI to work at all. What do I do?
Please call our Customer Service at 1-800-567-3556.
Can I use any other fuel than a 4 hour (15mm) tea light in my JOI?
No. Use of any other fuel can result in fire or injury and void your warranty.
I bought a JOI and can’t open the door. What should I do?
Sometimes during shipping the candle holder will get knocked off its rails. The door will only open about an inch. Using a device such as a pencil/pen, simply disconnect the two stainless wires attached to the door:
1. Insert your pencil/pen into the opening between the two wires and pull the wire towards the side of the door until it releases.
2. Repeat this process on the other side and the door will fall open.
3. Remove the candle holder assembly from the unit.
4. Slide the candle holder onto the two rails.
5. Reconnect the two ends back into the sleeve on the door.
I just bought some Ikea/Walmart tealights and they don’t fit, what’s wrong?
JOI is designed as a high efficiency device. The standard diameter for a tealight is 38mm, and the JOI candle holder was designed to snugly hold standard tealights including those sold by Ikea and WalMart. After the JOI went into production, Ikea and WalMart appear to have changed suppliers and manufacturing methods for tealights, and they are now 39mm. Not much difference, but they don’t fit. All other tealights do fit. For an immediate fix, purchase tealights from another source, such as ACE (USA) or Home Hardware (Canada). For a permanent solution, contact Caframo with the serial number of your JOI and we will send you a part that you can swap out in your candle holder to enable it to accommodate 39mm tealights. All you need is a Phillips screwdriver.
Does it matter if you use paraffin-based candles or soy or beeswax?
The material of the tea light is not as important as the size of the flame. The JOI light utilizes the heat from the flame to create electricity.
Is the JOI lamp waterproof with the top down?
It is fine to leave the JOI lamp outside. It should be waterproof and if rain does get inside it just needs to be dried out
What will void my warranty?
Caframo will warranty any product bought through a recognized retailer. Products bought through individuals or on-line auctions have no warranty. The warranty does not cover abnormal wear or damages resulting from accident, misuse, abuse or, if applicable, breakage (when such breakage is not due to a manufacturing defect) and any other incidental or consequential damages.
