Question: how to replace the batteries?
Document: The body of the flute itself is very nice, though, and the lights are aimed so that you get one spot of light about 3 feet away or more. The batteries are easy to replace, too; just unscrew the bottom white cap and the whole thing slides out of the metal body, lights, batteries, and all. Overall, a very nice light when you're waking up in the middle of the night and don't want to blind yourself.
This light puts out a very good amount of light. I am using it inside a gun cabinet and it lights it up like day. I do not like the on/off switch. It is hard to push and it sometimes falls off its mount due to that. I have had it for a few months now and have not had to replace batteries but it really only gets used twice a week for about 10 min. I would rate it 8 of 10 and would buy another.
I'm not sure what others see, but this light is pretty bright. It gives a good amount of light for small spaces, I would say not good for larger areas. If you need to light a small curio it works great. The included sticky pad is incredibly strong, it sticks to the ceiling no problem. If anything it chews batteries pretty fast. It takes 3 triple A's, and I've had to replace them once already from moderate use after a month. I would recommend this product.
The Light Flute has an easy to install base, which means you can put where you need it (no wires!) and, since it uses a powerful magnet t.o hold the light, you can remove and replace it as needed. The light is bright, white, and easily focused on your work, or in my case, your keyboard. Plus, it's solid construction and handsome styling make it well worth the price.
I really wish they replace the bracket with something that was more fitting for the light.I gave the light 4 stars because of the bracket. Otherwise, this is a great little light that can be used anywhere, closets, under cabinets, in cabinet shelves and in small places where you need a powerful LED light.Update: My lights that I have bought and used the sticky back bracket has fallen off 5 times. Think it's time to screw them into the wall. (ugh)
The batteries than came with it were pre-installed and were already close to dead so expect to buy new ones quickly.
great but the blue light only lights some things - batteries last approx 2-3 days 24 hour usage - I recommend this
I needed some bright light for jewelry shows and these are cheap and perfect. Don't know about battery life yet but I plan on using rechargeable batteries in them. So far it's great.
Can't see that it illuminates the area to any significant degree. And it has slipped out of it's base more than once when I turn it on or off. This is less bright than a night light - less bright than a flashlight with rundown batteries.
This should be a novelty in a dollar store, nothing more. WAY over priced. I can not recommend this product at all. The fact that the batteries don't last very long either is a mute point since I don't bother to use it any more.
Answer: yes
