Answers to all your questions about power outage LED lights.

Can I use SafeLumin with a dimmer switch?
No, the SafeLumin power outage sensor will not work and the light may flicker or buzz.
Can I use SafeLumin in totally enclosed luminaires?
No, the LED and battery will overheat and degrade prematurely. It is important to install SafeLumin in a well ventilated location. Only install in indoor operating environments between -5ºC and +35ºC (+23ºF and +95ºF).
Can I use SafeLumin with fan or incandescent and halogen bulbs on the same switch?

No, fan or incandescent and halogen bulbs are not compatible with SafeLumin. They will cause the sensor to falsely detect a power outage and turn SafeLumin on after the light switch is turned off. SafeLumin is only compatible with normal LED and CFL bulbs. 

Can I simulate power outage and verify SafeLumin function?

Yes, you can simulate the power outage with following setup:

  1. You need 1 power strip, 1 light fixtures such as table lamp, 1 SafeLumin, and 1 hair dryer (needed to simulate a load).
  2. Install SafeLumin into the light fixture (table lamp).
  3. Plug the lamp and hair dryer cords into the power strip; then plug the power strip into the wall outlet.
  4. Turn on light switch and hair dryer (hair dryer must be turn on full-blast).
  5. Turn off the power strip’s switch (to simulate the power outage).
  6. You will see light and hair dryer both go off, but SafeLumin comes back on in 1sec.
  7. Now turn SafeLumin light switch on and off to see it in action.

Advanced verification: Use “Main” breaker to cut “whole house” power (cut power at main breaker, not sub-panel breaker), and turn light switch on and off to verify SafeLumin works in your light fixture. However, this is unnecessary and we do not recommend it as many users are unfamiliar with the house breaker operation.

Can I unplug the lamp cord from the outlet to simulate the power outage?

No, Safelumin power sensing technology requires a closed circuit. Unplugging the lamp cord will not turn on the backup light.

To easily test the bulb by just unplugging the lamp, simply wrap the two prongs of the plug with foil. This trick will simulate a closed circuit and turn on the backup light if the switch is in the “ON position”.

How does the battery life test button work?

Battery life test button: Press the test button and you will see SafeLumin blink. 

3 blinks: Full charge (works 2-3 hrs)
2 blinks: Half charge (works 1-2 hrs)
1 blink: Low charge (works 1 min -1 hr)
0 blinks: Empty charge (works 0 hr)

If after several years of use it only blinks once after charging 6 hours that means the battery is degraded from normal wear and tear. You should replace it with a new battery to ensure proper functioning. Please contact us to order your new battery. www.safelumin.com

TIPS: If showing 0 blinks, check the battery wire connection to make sure it is secure. Then charge for 6 hours. If it still does not blink then replace with a new battery.

It is good idea for ANNUAL inspection at the same time you check your smoke detector.

How do I replace the battery?
Replacing battery step-by-step:

A. Remove screw. Set aside. Press the cover triple lines and slide off battery cover. Set aside. Grasp the white connector and gently pull the wire to remove the battery. Pull the small white connector apart.

B. The wire is color coded red and black. Take your new battery and latch the small white connectors together until  you feel the click and the connector locks.  Make sure your red & black wires  match.

C. Insert the battery bottom first and then tuck in the wire carefully. Position the battery cover half way over the opening and slide up to close. Add the screw back to the battery cover. Then press the test button to verify the battery is functioning.

D. Dispose of used battery promptly. Keep away from children. Do not disassemble and do not dispose of in fire.

I charged my brand new SafeLumin for 6 hours but it did not blink 3 times when I pressed the test button. Why?
In rare cases the battery connector may loosen during transportation. The simple fix is to disconnect (pull apart) and reconnect the plug as described above in “Replacing battery step-by-step” figure B. Charge again for 6hrs, it should then blink 3 times showing full charge.
Is this safe to use in a bathroom fixture?
Safelumin is safe to use in a bathroom fixture such as vanity light, however, Safelumin is rated for dry location. The powder room or half bath is considered dry location, so they are safe to use in this location.

Shower or bathtub will create humidity and is considered a damp or wet location, depending on the install location. If you install above the sink with a good exhaust fan to remove humidity, then it is fine. Do not install above the shower as this is considered a wet location.

Make sure the light fixture is open face for good air flow.

Attention: If your switch controls both light and exhaust fan, it will not work. “Fan” will cause the sensor to falsely detect a power outage and turn Safelumin on after the light switch is turned off. This is because fan has the same character as an incandescent bulb. Make sure your light and fan have a separate switch before installing the Safelumin. (Fan: means any type of fan, not just exhaust fan controlled by the same switch as the lights)

Will Safelumin light bulb charge even if lamp is rarely or never turned on, such as an unused bedroom?

Safelumin sensor system is constantly checking the power condition, so it needs battery energy to support the sensing operation when the light is off.

Our system drains very little battery. It will last 5+ months when fully charged. Safelumin suggests turning lights on 6 hours every 3 months to keep a maximum charge. That means turn lights on 6 hours every 3 months at least. This should be easy to do even in an unused bedroom.

Can I put one in a ceiling fan that has room for 4 light bulbs? I use the ceiling fan light every day. I just need one bulb for power outage.

Yes, there are ways to make a Safelumin bulb work with your celling fan. Two conditions need to be met.
First, the other 3 bulbs must be LED or CFL (not the glass incandescent bulbs), or it will cause false sensing when light switch is OFF.

Second, depending on how your celling fan is wired, both the fan switch and light switch must have separate control from the wall switch.
Here is simple test to check how your celling fan is wired. Turn ON both “fan pull chain switch” and “ligth pull chain switch” to see light and fan are running. Then turn OFF the “wall switch” and observed which wiring you have.
1) Wiring A: If the light is OFF and fan is still running, then you have correct separate control, a safelumin bulb can work in this celling fan. Not a problem.
2) Wiring B: If both fan and light are OFF, then you do not have correct wiring. If you put a Safelumin bulb in this celling fan it will cause false sensing, unless you turn OFF the fan pull switch when the light is being turned OFF. In other words don’t leave the fan running when you turn off the wall switch. Then it could work, but it is a bit tricky with this wire setting.

So, if you have LEDs/CFLs on the same light fixture with Wiring A for the fan, then there is no issue to install a Safelumin bulb.
But if you have LEDs/CFLs on the same light fixture with Wiring B for the fan, then it will case false sensing unless you turn off the fan from the pull chain switch before turning off the light at the wall switch.

We hope this info helps!

How long do the batteries last? I see that the replacement batteries are pricey.

We expect the battery to last 3-5 years maybe up to 10 based on normal use and relevant temperatures. Hot is not good for the batteries but safelumin is the coolest bulb due to our air gap design. The new rechargable batteries are shelf stable for 10 years. 

What is the difference between 2700K, 3000K, 4000K and 5000K bulbs - they have the same price?

The 2700K/3000K/4000K/5000K is referring light color temperature. 2700K-3000K is warmest, and 4000K-5000K is coolest. Please see Color-Map image below for visual different. Most people order 2700K soft white for home use, while some application prefer 5000K daylight for brighter white.

How do you power ON the bulb? I've depressed the button which shows the bulb is charged by flashing 3 times but the flashlight feature does not work.

To “Power ON” the bulb, simply install Safelumin into any lamp / light socket, then turn on the light switch for 10sec.

The Flashlight & Power Sensor deactivated prior to shipping. Power ON the bulb to active ALL functions.

The flashlight feature does not work. I've tried the button, and using foil.

Does rechargeable bulb charge when the switch is off?

No, the Safelumin rechargeable bulb will not charge when the light switch is OFF.

To charge the battery, the built-in charger needs to work with electricity. By turning on the light switch, electricity is allowed to flow through the bulb and activate the charger function. The battery charger will recharge when the battery is low and auto stop charging when the battery is full.
