Question: Does it give enough light to paint the average size room?
Document: This lamp puts out a lot of light. Enough to illuminate a 12X15 room.Light is adjustable with a simple knob
This lantern is rather large but the light it gives off is not that impressive. It is now good for a moderate area. I tried using it in a shop and hanging from the ceiling and it was essentially useless. There are smaller lanterns that use fewer batteries (than 8 D size batteries) or are rechargeable that can give off the same amount of light. It may be good for placing on a table and using to play cards or something of that nature.
The dial is not 'totally variable', there's 'off' and seven levels of brightness, which is five more than most lanterns.The lowest light setting is basically a night light, so you don't trip over sleeping people. Every setting above that is bright enough to comfortably read by, when sitting within five feet of it. Making it brighter simply lights up more and more area.This needs a LOT of batteries. When full of 8x D size batteries, it is NOT lightweight.
This LED lantern supplies enough light to safely light up a room. We experience power outages during storms on a regular basis here and these lanterns are more than adequate for lighting our home. We would recommend them to anyone looking for emergency or recreational lighting.
This light has amazing white light illumination which is capable of illuminating a large room or outdoor area. The rotating power knob controls is easy to use for seniors and dims the light output to suit various room sizes or areas. Under normal use you should get about ten days of battery life using the eight D size batteries (not included) in the base.
We bought this lantern as a standby light for our frequent power outages here in the third world (Montgomery County, MD), and we haven't needed it yet. But testing so far shows that it's bright enough to light up a whole room, and to read by quite comfortably. It's quite substantial: large and heavy (the weight is mostly batteries), well-made, and very easy to use: click on, dial up the amount of light you want, click off.
When the power goes out, this lantern saves the day! You can adjust the light produced from very low to very bright, it's portable, doesn't get hot, isn't dangerous like candles, and runs on low  for hundreds of hours on 8 D batteries. On high it will light up a living room. We bought two after Hurricane Sandy left us powerless for 9 days and like them so much we bought two more to give as gifts to friends.
Got this in case needed. Very nice size, good that I can adjust the light. Completely satisfied with this product.
The light level control of this particular model is also very versatile but intuitive (turn a dial to control brightness). I would not recommend these for hiking or backpacking due to their size and heft. However, they are perfect for blackout situations at home and tent camping.
Good value for the price. It uses common D cells and puts out enough light to actually read by. Very well constructed too.
Answer: yes
