Question: how long do batteries generally last
Document: the batteries last a long time and the light is great to work on close up work like making jewelry love it
I cannot attest to how long the batteries last since I haven't really used it on batteries so far. But it's a very bright light.
The 3 D batteries last a super long time thanks to the LED's lights not hogging much energy.In my motorhome, I put a wide strip of velcro on my dining booth table next to the wall. I stick things there with the matching velcro on their base, so they won't fall and break when I am bouncing down the highways and byways. I put velcro on the bottom of the lamp.
love it great light  fast shipper great price  the babtteries last long time in these led flashlights gives you a broad beam
Pros:  Big batteries = long life. Two settings: high beam and low beam, which is another way to prolong battery life.Cons:  I ordered two lights. One of the lights had one of its led lights that flickered, making it useless for reading, but OK as a flashlight.
I had purchased a similar product (from Amazon) a year ago that had 20 LEDs. And it worked fine, even on long-expired Duracell batteries. So, I was dubious of this "30" LED version...thinking that it was just a gimmick, and that it wouldn't realy be any brighter (...oftentimes, in such products, more LEDs just means that the battery power is re-distributed...with no increase in brighteness).
Very bright and dual intensity is a plus. Being LED, batteries last very vell. This is a replacement. My first one shattered into tiny pieces when I dropped it aout 6 feet.
Very nice and useful light that is exceptionally bright, considering past LED lights I have seen. Works on three D cell batteries that seem to last well. Perfect for that loss of power that we all suffer through now and then. The heavy base and tilting head make it easy to use for odd jobs around the house also. I recommend it highly.
After the last three-day power outage, I decided to buy yet another light for the next time. I bought the SE 20 LED light previously and have had a good experience with it. For a little more money I decided to buy the 30 LED light this time.The light is powered by 3 D batteries which are inserted into the lamp's base.
The hook is very cheap and small compared to the weight of 3 D Cell batteries. I am to scared to use it.I didn't notice that although it will take AC input, it does not come with an adapter. You need to have a 4.5 volt 1.5 Amp adapter.After using it for 2 months, I love it. The batteries last forever, I have accidently left it on 3 days in a row and it is still working great.
Answer: yes
