Why do I need light after plugging it in?

Works as expected, BUT the LED remains lit as long as the device is plugged into an electrical source. Obviously, I won't need the light to indicate where my phone is after it has been plugged in. Could they not have designed the circuitry such that the current will not flow through the LED once the charging circuit is closed?

It's a bulb. You switch it on and it gets glowy and bright.

The bathrooms are fitted out with these now and they produce even more light than the old incandescents. They also reach peak "glowiness" much faster and they're practically instant-on. All 6 of these bulbs combined use less power than one of our old incandescent bulbs.

I got it for a lamp and it worked every once in a while at best.  I tried moving it to another plug with every once in a while there too.  We ended up with a motion sensor light switch instead and I love that.

Light is to help you sleep and not get wound up on the blue lights of regular light bulbs. When I wake up in the night it doesn't keep me awake.

When first plugged in, there is a slight ozone smell for a little while but it fades away. We have 4 of these throughout the house and  basement for blackouts. They're very bright but also very small so we don't even really notice them anymore where they're plugged in.

I just got it today and screwed it into a light that comes on with motion sensing. The outlet is being used for a wifi camera so I don't have to run an extension cord to my entry way. It works great! Just remember that if you turn the light switch off, power to the outlet goes out too. In my case, my camera would turn off (be without power) if I turn the light switch off. If it stops working, I'll update my review, but so far, this is just what I needed.

It doesn't work properly. When I plugged it into an outlet which is known having no ground, its 3 lights are on, with the center one brighter than the other two.

It is very convinient to have small light in the bathroom at night.  In case of power failure it goes on automatically.  And you always have ready to use flashlight. I love it.

I think its vital to have some sort of light when things go wrong ie. power outage, camping...where's the batteries? Don't even need to think about it with this product! You can charge AC or crank it up. I wasn't sure if it would be bright enough...discovered it was.

Had to plug and unplug a few times to get it to work. This is 12v so you have to switch your PC on for it to illuminate. Most people complain its not bright enough, I think its fine for the price, you want brighter UV you pay for brighter UV lol.

Use the lamp switch. That is what it is there for.

Sometimes the leds go out so I'm not sure if my batteries are completely charged or not. I just unplug it for a moment and that seems to reset it.

Good product but unfortunately there is no signal, light, or switch to indicated whether it is on or off. You just have to plug it in and hope that it is on. If not, you just turn the cheap switch that is on it until you figure it out.

I connected it, the light came on but the device did not work! I ended up using my car battery.
Am I supposed to connect it and wait for a while? I have not tried doing this.

Did you get one and think it was defective? I did, but it was just me not thinking it through. If you put the batteries in it in a bright room, the light sensor will (of course!) keep it from turning on in a bright room, movement or not, as that would just be a waste of battery power. Take it to a dark room and wave your hand and see if it works before you decide it is bad - chances are it works fine! Great little device.
