Power Failure Emergency Lighting SK638 Review


Growing up in California power outages and rolling blackouts were common, especially during the summer.  This may be one of the reasons I’m a collector of emergency lighting. My collection varies widely mostly focused on off-grid lighting. However, my collection of lighting was lacking power failure options so I was delighted when Ideal Security contacted me to see if I would write a review on their SK638 Power Failure Emergency Light in exchange for the product.


Brightness, battery life, and functionally are the features I value the most when considering an emergency lighting resource. Ideal Security has done a great job designing the SK638. Several of my emergency LED lights range from 30 – 65 LUMENS so I like the 6 – 120 range this unit provides. The battery life and longevity seems to be fairly good for LED emergency lights.  The portability, night light sensor, and power outage detection make this a useful device to have around.  I’ve used the device for almost a month now and so far I can’t find anything I dislike about the device.  The listed price is $59.99.

Power Outage Detection 

The main feature to look for in a power failure light is that the device can detect the difference between a power outage or the light switch just being off.  When the device detects a power outage it will automatically turn on. That way if a power outage happens at night you won’t find yourself blindly feeling around in the dark trying to find a flashlight.


Portable Emergency Light & Wall Mounting

The SK638 ideally is free standing and is plugged into a power outlet.  Additionally, it can be used as a portable lighting resource by unplugging the AC adapter.  There’s a hand grip in the back of the unit for easy carrying. When the AC adapter is unplugged it functions like a typical led lighting device with a switch for turning it on and off. This feature allows a person to move from room to room locating emergency supplies, keys, and cell phones. The unit can also be mounted to the wall using two anchors and screws which are included. There is a Wall Mount Template to help with the accuracy of getting the screws aligned properly.


Night Light Sensor

One of my favorite features of this light is the night-light photocell sensor.  The SK638 can be set so one of the six LED bulbs turns on at dusk and off at dawn. I have placed my SK638 in a hallway adjacent to bedrooms which is helpful to over-night guests. It’s an energy saver compared to leaving a hall light on all night.



Other Tech Features

  • Charge /Power Indicator – a blue light turns on when the unit is plugged in and being charged
  • Test Function – there is a black button that when pushed will show you how the device will function when power is disconnected
