Will PowerSure® products be UL tested?

PowerSure® brand Power Failure Lights will be tested according to all applicable UL and other NRTL safety standards. These test standards must be performed on production quality manufactured units and therefore will be tested and certified once that milestone is reached.

How often do I need to change the batteries?

The internal batteries will last a very long time - up to 10 years if you have no power failures (see next two questions), but a simple test will tell you when it is time to change them. Plan to test them 4 to 6 times a year (see maintenance below).

How long do the batteries last if I don't have any power failures?

The standard coin cells will remain ready to power the light and have a rated shelf life of up to 10 years without leaking or corroding. The rechargeable cells have a shelf life of approximately 6 years.

How long do the batteries last during a power failure?

Standard coin cell batteries will provide approximately 4 nights of lighting during a power failure if the safety light is located in an area where daylight provides enough light to turn them off. If the PowerSURE Power Failure light is in a windowless room area where no daylight is available, the power failure light will turn on whenever there is a loss of electricity. The night light will be on whenever the room lights are off and the electricity supply is normal. In this case, the coin cells will last approximately 30 consecutive hours before becoming exhausted.
When fully charged, the optional rechargeable batteries will last for approximately 4-5 hours during a power failure and will take 24-36 hours to fully recharge once power returns.

Will the switch or receptacle have to be replaced after the batteries run out?

No. The main body including the switch or receptacle remains permanently installed. The LED module is removable and contains the coin cell batteries. Once the batteries are changed, simply insert the moduld back into the main body. Rechargeable batteries do not need to be changed unless they fail to fully charge. This may happen after 500 or more power failures or after approximately 6 years.

How bright is the night light?

Night light power is reduced to a level that makes it easy to see where you're going at night. A light bulb for a standard night light will provide about 20 lumens of light in a 360° sphere. Since PowerSURE Power Failure lights are a point source directing a beam of light from a wall in a much narrower field, we've found that approximately 1 lumen is plenty of light for night lighting purposes.

How bright is the power failure light?

As in the description for night lights, we've set the power of the LED for power failure light to approximately 4 lumens. This is very bright for the human eye and we do not recommend looking directly at the light when it is on during a power failure.

Back to the top

Does the switch work if the batteries run out?

Yes. Both the switch and receptacle perform their intended functions whether the batteries are fully charges or exhausted. There is no common parts between the main AC power functions and the lighting function.

How do I know if the batteries are low?

Place your finger over the small clear light sensor and push it in. A small switch inside will cimulate a power failure and try to light the LED module. If the LED appears dim or does not go on at all, then the batteries need replacing or the rechargeable batteries have not had sufficient time to recharge. In that case, please wait for 24-36 hours and try again.

Back to the top

Are PowerSURE Power Failure Lights UL approved?

Safety tests by UL or other Nationally Recognized Testing Laboratory (NRTL) are required for any electrical device and will be performed and certified before being made available for sale. Since these tests require manufactured and production quality devices for the tests, we have not yet started the testing process. Be assured that they will be rigorously safety tested.

Can I replace ANY switch with a PowerSURE Power Failure Light switch?

The first model of PowerSURE Power Failure Light Decorator style switch will replace most 15 Amp light switches. The switch is a standard single-pole switch. This means that it controls a light or other load from a single location. At this time, it can't be used in a 3-way or hallway light circuit - the type used at two ends of a hall, staircase or two entrances to a large room to control the same light. In addition the PowerSURE Power Failure Light switch requires a neutral wire to operate the safety light circuit.

Back to the top

Can I replace ANY receptacle with a PowerSURE Power Failure Light receptacle?

Yes. The receptacle replaces any standard 15 Amp receptacle. If the location where you are installing it requires GFCI protection, you must connect it to the "load" side of an existing GFCI receptacle. In this way, the GFCI will provide protection on any devices that are connected to the "load" side. Please consult with an electrician in your local area for guidance on requirements for GFCI protection.

Why does the switch require a neutral wire in the electrical wall box?

The neutral wire allows the circuitry internal to the PowerSURE Power Failure Light to connect to a complete 120V AC circuit for proper operation. If there no neutral wire is available, the safety light will behave as if there is a power failure. The LED light will stay on when it is dark until the batteries are exhausted. It will still work as a standard switch.

Back to the top

What is a neutral wire, and how do I know if I have one?

Warning: You should consult a qualified electrician familiar with all the local codes and ordinances when working with electricity.
Before planning to install a PowerSURE Power Failure Light, you should turn off the electricity to the switch that you want to replace. Remove the wall plate cover and use a flashlight to look at the wires in the wall box. If you can't see them, then you may have to pull the switch out far enough to see them. If there is only one pair of wires entering the box and both wires are screwed to your switch, there is no neutral wire. If you have three wires attached to the switch, then it is a 3-way or hallway light switch and you can't replace it with the current PowerSURE model switch.

If there are more wires in the box, look for two or more white wires twisted together. If you find this group of wires, it is likely that you have a neutral wire available.
When replacing an electrical receptacle (or power outlet), there is always a neutral wire for the complete 120V AC circuit. Again, we recommend that you please consult with a qualified electrician.

Can I put more than one PowerSURE Power Failure light in the same electrical wall box?

Yes. PowerSURE Power Failure lights conform to standard National Electrical Manufacturer's Association (NEMA) size specifications and will replace any standard switch or receptacle. If you desire more Power Failure lighting protection in a given area, you may put them side by side in a multi-ganged wall box.

Back to the top

Can I mix PowerSURE Power Failure Lights with other switches and receptacles?

Yes. See the answer to the previous question.

Do I need to connect a ground wire to my PowerSURE Power Failure Light?

The National Electrical Code specifies which type of devices require ground wire connections. PowerSURE Power Failure Lights come equipped with a ground wire terminal screw to conform to such requirements and regulations. Warning: You should consult a qualified electrician familiar with all the local codes and ordinances when working with electricity.


What is a multi-ganged electrical wall box?

When you see more then one wall switch or receptacle installed side-by-side in the same wall box and covered with a single wall plate, the wall box is a multi-ganged electrical wall box. Multi-ganged boxes can be found in many locations in a home, usually near entry doorways.

Back to the top

Do I need an electrician to install these products?

Local electrical and building codes vary in different cities, states, and other jurisdictions and may require you to call an electrician. We strongly recommend that you have an qualified electrician install these devices according to all national and local electrical codes if you do not have experience installing these types of devices. Read and follow all installation instructions carefully.
How do I change batteries?

Remove the wall plate. Grasp the LED module firmly by the sides and pull it straight out. PowerSURE Power Failure Lights come with the ability to lock the module in, so be certain that the interlock mechanism is unlocked. See the instructions supplied with the unit. Once the module is removed, replace the wall plate. Take care not to bend the contacts when handling the module. Slide open the cover of the module and remove the two coin cells. Replace both cells at the same time with CR2032 coin cells, positive side up. Replace the cover and slide the module back into the main unit until it is fully seated.

Can I turn the night light off?

Yes. Move the small switch located on the face of the LED module to the left and the night light will will not turn on when it gets dark.

Back to the top

If I turn the night light off, will the power failure light still work?

Yes.

How often should I check the batteries?

There is no specified interval to test the batteries, but every few months you should press the button marked "Test" on the bezel of the switch or edge of the receptacle.

Back to the top

If the night light stays on all the time, will the batteries go dead?

No. The batteries will not be used as long as there is main AC power.

Do I need rechargeable batteries instead of regular batteries?

It depends. We recommend that the standard batteries be used unless you are prone to frequent power outages in your area. Rechargeable batteries are great if your power outages last for one night and happen often. If the PowerSURE Power Failure Light is in a more commercial setting, you may want to install rechargeables and lock the LED module in place to reduce tampering and maintenance.

Back to the top

Can I buy rechargeable batteries at a local hardware store?

No. Rechargeable batteries are available from PowerSUREF directly, or your electrician's distributor.
Can I replace rechargeable batteries with regular batteries?

Yes. Although both battery types fit in the same LED module, separate circuitry is used for each type. This insures that the coin cells do not get charged and enables you to put locally availabole coin cells in during extended outages.

Back to the top

How do I replace the LED bulb?

The LED bulb should never need replacing. It has a life span of 100,000 hours, which is more than 11 years if it was on at full power 24 hours a day. In the rare event that the LED needs to e replaced then replace the entire LED module.

How do I lock the LED module so others won't open it?

The PowerSURE Power Failure light may come with locking pins to be inserted before installation. Since the pins are accessible from the side of the unit, the circuit breaker to the wall box should be turned off. The pins may be inserted after removing the PowerSure Power Failure light from the wall box. See the instructions supplied with your unit.
Back to the top

Is it safe to repace batteries without shutting off the electricity?

Yes. Removing the wall plate allows you to grip the LED module and pull it out. Replacing the wall plate at that point further enhances safe handling. The PowerSURE® Power Failure light has extra wide shoulders to keep you from coming in contact with any high voltage wires. As a precaution, you should visually inspect the side areas near the shoulders before grasping the LED module to ensure the unit was installed properly and no wires protrude from the sides of the unit. If so, we recommend that you turn of the circuit breaker for that wall box and reinstall the unit properly.

Do these products require strict periodic testing for emergency use?

No, but we recommend periodic testing. PowerSURE® Power Failure lights are not approved for emergency life safety use at this time. Local code requires all emergency life safety power failure lighting to be tested at regular intervals.
Does the main receptacle or switch work when the batteries are dead?

Yes. The main AC functions are not related to the battery powered functions.
