Question: how many led lights are there, just one or several?
Document: Unplug it, fold the prongs into the light, flip on the switch, and you have a handy flashlight, not quite as bright as a regular flashlight, but accessible and always ready for action. We have had one of these convenient little lights for some time, and just got another one. There are good for many situations.
These lights are simple and functional. There isn't a single thing to dislike about these. I bought several for other family members. One previous review stated that the light was only marginally bright, I disagree. They put off a fine amount of light for their size. I also love the fact that the plug and charger are built into the light. Simply flip the plug out and plug it into any wall receptacle.
Have five of these scattered around the house. Got tired of picking up flashlights with dead batteries (too many kids); when the lights go out. They work great.
I needed to replace a couple of old emergency rechargeable lights. After looking at many different lights, I selected this Energizer Model. The perfect choice.
These are great little lights. I purchased them to put in several of my houses, in hallways, for emergencies. I also gave them as gifts.
I bought 5 of this lights. Here in the dominican republic the light is gone every day several hours. This light is handy and usefull. Iam happy to have it.
I have placed these lights in several rooms of my house. So if the power goes out (and it does a lot in South Florida) they will go on and especially at night I will be able to see where I am walking.
This is exactly what I have been looking for as a gift to my husband. So many companies have discontined makin them so this one is perfect for our needs!
I really depend on this light for many emergencies. I would recommend that everyone have at least one. Now I have two. The only negative is I have since found them at Walmart for 8.88 which is a few dollars less expensive. Can't beat this torch, british for flashlight
I bought three of these flashlights and I love the brightness, the duration of the light, and the price is very reasonable. One fell out of my pocket at work and broke. It was only about three weeks old and was the first time it had been dropped. A flashlight should be able to survive being dropped many times. I'm very disappointed with the fragile engineering.
Answer: yes
