Question: why does the red light come on?
Document: I had anticipated being able to unplug the unit and use it as a flashlight. Apparently it must be &#34;dark&#34; before the sensor will allow it to come on. So, it can't do double duty to illuminate that junk drawer to help locate a rubber band, safety pin, etc. There is an &#34;on&#34; setting, but it only turns on the night-light.
In a dark room, either the dim light is on (if AC-powered) or the bright light (if not AC-powered).Normally, you don't think about this. You just set it to "auto" and plug it in. The dim light normally acts as a night light; but if the power goes off, you have a bright light handy.All this is good, but there's one defect. When the unit is AC-powered, the bright light should never come on.
Purchased this light about 6 weeks ago, and it has been working fine. Overall, it's a good night/emergency light, though, weird operation (e.g., cannot turn on the bright light unless it's dark enough for the light sensor to enable bright light). As others have already reported, there is one defect: When the unit is AC-powered, the bright light should never come on.
I received a unit and after a full charge it was extremely unpredictable. When the power would switch off, the light either didn't come on or constantly flickered. Subsequently the light remained on even in the "Auto" position when plugged in and continued to flicker. I requested a replacement. Battery1inc was fantastic about this and their customer service is excellent. They instantly sent me a replacement even before I shipped back the old one. However, this one too had the same issues with flickering.
"I tried this procedure with both lights twice, with no change in performance. I replied and let them know that their solution didn't work, but they never replied to that. I assume that means they don't have a solution.If you don't mind an odd flashing twice a day, these are good lights. I've lost power several times, and they always come on and stay on very bright until power is restored. All features and switches work as advertised.
Really like the nightlight (dim light) feature, though.
Very good light . Works perfectly, lasts long time on single charge.
Bottom line, use this item as night light/emergency lighting and buy yourself and emergency wind up flashlight. I hope this has helped.
The tiny little switch is made of cheap plastic and broke off the first time I used it. There is no way to reattach it, so I returned the light for a refund.
Using this for emergency purposes to have easily on hand. We have it plugged in a couple of places to always keep it powered up and if/when needed we have a quick night light.Very handy and love the size.
