Eco-i-Lite Nightlight is Secretly an Inductively Charged Flashlight

Eco-i-Lite 3-in-1 4LED lightMany companies sell plugin emergency flashlights, but what makes Capstone’s Eco-i-lite series cooler than most is that it charges inductively just like some toothbrushes and phones. You can’t screw up putting it away because there’s no incorrect position, simply slide it back into the base and it’s charging.

Capstone sells several models of the Eco-i-Lite which differ in regard to functionality and number of LEDs.

The 4 LED 3-in-1 Eco-i-lite, shown above, plugs into an outlet to recharge its built-in lithium-ion battery, which can power the flashlight for up to 4 hours per charge. The plug rotates so the flashlight is always upright whether your wall outlet is right-side-up, upside-down, or sideways.

The Eco-i-Lite turns on automatically when it senses that the outlet has lost power, so that you can easily find it in a blackout. There is also a three-position switch, so you can use the flashlight manually. It also can sense when the room darkens, and when it does it goes into a special lower power nightlight mode.

Going up in functionality, the Eco-i-Lite Power Failure Lights also have a separate 3-position power button for setting the flashlight to on, off, or flashing modes. The 4-in-1 models have an additional light on the side for extra utility.

Here is a complete list of the Eco-i-Lite models:

  • 4 LED Power Failure Light
  • 6 LED Power Failure Light
  • 3-in-1 Light with 4 LEDs
  • 3-in-1 Slim Light with 4 LEDs
  • 4-in-1 Light with 8 LEDs
  • 4-in-1 Light with 16 LEDs

The models with higher LED counts are sometimes advertised as 5 and 10 LED lights. The 8 LED model has 3 of those LEDs for its nightlight mode, and the 16 LED model has 6.

The 4 LED Eco-i-Lite will run you about $10 at Home Depot, or you can pick up a two pack of the 16 LED 4-in-1 Eco-i-Lites for $31 including shipping. The 16 LED model has 10 that can be used in flashlight mode, and 6 that are used in nightlight mode. Other models are priced between these two.

Don’t think would be useful? Imagine that you are ripping boards on the table saw in your windowless basement shop when the power fails. After you grope for the table saw off switch (so that it doesn’t start up automatically when the power returns), you scan your shop to see faint red and green lights from your various chargers. You head in the direction you know the door is located and slowly start towards it. Midway there, you slam your hip into the edge of the workbench. As you climb the stairs to find the sliver of daylight peeking out from under the basement door, you make a mental note to yourself: “I’d better get one of those emergency flashlights.”

    I think i may get some and try these.would be good for the man cave area and garage.

    Wonder if you leave it on the charge up base all the time does it stop charging on its own? I would assume so,just wondered.

    I’ve had automatic power failure lights in the past, and I had one gripe with them. They were awkward to use as a grab-and-go light. The kind I had plugged directly into a recepticle via a little folding plug. You had to always fold and unfold the little plug, and if you had something in your hands, it was hard to grab, and almost impossible to plug back in one-handed. I would really like this, because 99% of my uses for a light like this would be to have an always-charged grab and go light when you need to take a quick look at something in the dark. Just being able to grab a light you know had a full battery, and having it recharge just by dropping it in the ring seems to me to be a clever, and handy invention.

    I purchased something similar form Costco a couple of years ago. They include a second light that shines out like a nightlight. I love them. I bought them on sale for basically $5 a light when they were changing the packaging. I wish I would have purchased a few more! I could not find them online and cannot recall the brand.

      I got these too, and really like them. Wish I’d seen the $5 deal, they would make great small gifts.

    A few years ago, I bought a couple of sets from a warehouse club that were GE branded. I don’t know who the actual mfg. is though. They are inductively charged, and are very close in appearance and size to these. Mine have an extra set of LEDs in the side that light up in nigh-light mode.

    They have saved us a few times with power outages. Nothing worse than being in a cluttered basement or taking a shower at night and and a sudden power outage comes along!

      Correction: The label has ECO-Light by Intertek not GE. My mistake. An updated version can be found on Amazon: http://www.amazon.com/Eco-Lite-Function-LED-Lights-Pack/dp/B008VAY10G

    I have the one shown in the picture. Works great as a night light and it is a decent flashlight.

    I have an eco lite that the flashlight doesn’t work any more, can the battery be changed or just throw it away and buy a new one?

      You would have to contact the company, but to me it doesn’t look like the battery is replaceable.

    Bought one of these years ago, made by a company called intertek. Its a 3 LED flash light with one LED night light, made in June of 2012.
    Its been floating about the last few years as separate pieces (flashlight and charger).

    I finally got both corralled together and after not working for probably 5-6 years, I plugged it in and it works just fine.

    It was never the brightest night light, but usable. The flash light by todays standard is not bright. but with 3 LEDs, its plenty bright enough to use for and emergency light.

    I can only imagine over time that they have been able to improve the lumens while conserving battery power.

    If the old one is any tentmate to the new one, its well worth the investment.

    When charging the first time for 24 hours per the instructions, what setting does the switch need to be on?

      I’m not sure it matters. I don’t think the position of the switch affects charging the battery, it just turns the nightlight/flashlight part on. I’ve always just left mine on auto.

      Have you contacted the company? Generally products like these are not designed to be repairable.

      Unscrew the top (clear lens / flashlight side) – it’s basically a firm twist lock. Then split the housing from the top – as you do that the two halves will separate and pop out of the orange night light cup-shaped lens at the bottom. Inside there is a rechargeable 3.6v LIR2450 battery, a flat watch type battery.

      The battery is soldered to the leads so it’s not meant to be replaced, however I plan on replacing them (I’ve replaced other non-serviceable lithium ion batteries which were soldered in place). I was googling for any tips and found this post.

      (My philosophy is that since all products are made to be produced, I just need to reverse the production process to service it. The trick is to figure out the production process without breaking the thing. This device clearly has no service capacity but the factory isn’t going to be manufacturing something in a complicated way – they’re going to make it so it can be assembled in a few seconds.)

      I was hoping to install a higher power battery so it would last longer when the power is out, but I think it’d be a fire hazard so I’m going to stick with a similar size battery.

      We have a bunch of them and they all started to fade at about the same time, which makes sense because the battery has been charging consistently for a long time (10 years minimum, probably older than that). Super useful for the odd times that the power went out. It’d be a waste to not reuse them.
