Question: How to use these bulbs?
Answer :Replace your old bulbs with this new bulb in your lamp and use it as a regular bulb, it will work normally when there is no power outage, and it will continue to work for 3-4 hours when there is a power outage; You can also screw the bulb into our bulb cap (with a hook) and light it up with the on/off switch built in the cap, this way you can move the bulb around wherever it is needed; Or you can use your fingers/damp cloth/conductive materials to touch both the tip and the threads of the bulb base to light it up.
Question:
How does it work during outages?
Answer :During power outages, as long as the light switch is on, the light bulb in the socket will stay on for more than 3-4 hours. Tip: to test the bulb even without a power failure, simply place the bulb in a lamp socket, and turn on the switch of the lamp, plug out, use a wet cloth or wet tissue connect the prongs of the plug, bulb will turn on.
Question: Why the bulbs won’t turn off?
Answer :A small fractions of household’s circuit designs are not “typical” and the bulbs will stay on even when switch is off.

YKDtronics 5W Backup LED Light Bulbs with Rechargeable Battery. I was impressed by these lights rite out of the box. I have had a lot of fun with these lights. Because of the design of the light unscrewed from hook switch and or lamp, outlet, the contacts for completing the circuit are rite there at the screw end. The fun I mentioned earlier well I put the light in my mouth touching the center contact with my tongue to complete the circuit and the light would then illuminate I know you shouldn’t put things in your mouth in all great light many uses like…
Really bright! This is so bright! I have to be honest, I bought then for some outdoor lanterns but they are just too much. Moved then immediately to our emergency area in the basement and couldnât be happier that I have them there now!
Great bulb but still some kinks to be worked out 1. Bulbs worked great in a power outage, good light output. However’ even when the electricity is on and the light switch was turned off the light still came on, eventually after about 5 minutes the light went off. Not sure if this is some fault. The light is only supposed to come on when the light switch is on.
