Question: How much does it weigh without the 4 D-size batteries?  Am considering it for a x-c ski trip.
Document: Pros: Gives up much more light than our prior energizer lantern, but the light seems easier on the eyes. Easy to set up on a table, or fold and carry with you.Cons: 4 D batteries are not included, and since they should last a long time there is the risk of them leaking if left in the product without being used for extended periods. This means I have 4 batteries in a drawer next to the light and have to put them back in whenever I want to use it.
The lantern is price right for this size and only required 4 D size batteries  This is for the next storm.
This is a great lantern to have handy if the lights go out suddenly at home or if you're on a camping trip. The lights are very bright and can illuminate a wide area. It has a convenient carry handle and a wide enough base for it to stand securely. It also flips open so it could be used in a desk lamp configuration, convenient if you're reading or writing. It requires several "D" size batteries to run, making it somewhat heavy but not uncomfortably so.
I will definitely be springing for about three more of these - so much safer than candles (if knocked over accidently).Tip: To get the most out of the batteries (4 'D'), it's best to leave the setting on low.Good stuff!ENERGIZER WEATHER READY FOLDING AREA LANTERNSize: 8.9 x 6 x 3.2Weight: 1.2 Pounds
We spent six days without power due to Sandy. Of the various products I had purchased after Irene to provide emergency light, this lantern was the best. We used it in our living room, where we spent most of our waking time due to the wood stove. It provided plenty of illumination for the biggest room in our house so we could get around without stumbling over furniture or pets. Battery life appears to be excellent. It's still running on the original set of D batteries I installed.
Bought this for a camping trip and loved the size and ease of carrying it around. Hung on a tree and used to light our camp area. Great value for price!
When hurricane Irene hit Connecticut I was without power for a week and this lantern performed flawlessly over many hours of use. It provides enough light to easily light up an entire room. Even though the batteries I had were old, I never had to replace them that week as the LED bulbs use very little power. I liked this lantern so much I bought two more of them in anticipation of the next power outage.
We are onto day 12 with no power in NJ after Hurricane Sandy. I had one of these lanterns, along with 3 other lanterns, all different brands. 2 of the other lanterns take 8, that is right, 8 D batteries. And they last about 12 hours. THIS lantern, takes only 4 D batteries, and I have yet to replace any of them.
LEDs in this lantern are simply connected to batteries through a series resistor. Therefore its power consumption (and hence brightness) decreases rapidly with lower battery voltage.- When powered by a set of 4 fresh alkaline D cells (1.5V*4 = 6V), the lantern consumes about 3.2W of power in HI setting.
I had bought a few of these (luckily) before the winter ice storms hit Georgia earlier this year. They were pretty much life savers on keeping us out of the dark. Excellent substitute over gas lanters (no smell) and decent battery life. We ended up loaning some out to neighbors that were without power for about 3 days also and the batteries are still going strong. One neighbor loved the nightlight function as it helped comfort their little girl. Ended up letting her keep that one.
