Question: Can you replace the LED?
Document: My sister had purchased one of these, and we loved it so much we bought two more! They are the perfect ourdoor lanterns. Runs on 4 or 8 D batteries. Has three settings from brightest to low. Great LED light. Light weight, too.
The light is fairly pleasant, with little glare and without the harsh blue tint that some LED lights have.One thing that concerned me was the storage life of the batteries in the lantern - it doesn't have a hard-wired on/off switch, but a button that cycles between off and the three brightness levels.
I have one flashlight with a regulated power supply that remains at full brightness until the battery is completely dead and then abruptly shuts off, which is perhaps not what you want in an emergency situation (or in pretty much any other situation, come to think of it).I also like the fact that its dimming modes don't produce the "strobe-light" effect that some LED lights do.
A small Coleman LED that takes 3-D batteries had died after 4 nights on full power, used intermittently. Likewise we'd exhausted about 1-1/2 bottles of the quart-sized propane canisters on our Coleman double-mantle lantern (running on about 3/4 power) after 5 days.
This lantern has everything I was looking for in a full size lantern. It's bright, durable, no glass, LED, floats, water-resistant, has three light output modes (low/med/high, no annoying strobe), and it can take 4 OR 8 D size batteries which last a very long time (fewer batteries makes it lighter to carry).
This is my 4th GE  LED lantern. I picked one up at Costco some years ago, and have bought 3 more since. The battery life is very good, and on the lowest setting you can still read from it. The highest setting will fill a large  room with enough usable  light, and they have all been trouble free so far. I even purchased a pair for my sister&#8217;s family.
This lens has no obstructions and throws and even white light over a fairly broad area. Plenty of light to read by. While the weight of the lamp becomes a bit heavy with eight D batteries, it is still easily moveable but I wouldn't want to pack it in for a camping lantern.We got  our lamp at COSTCO for just under $20. Even though the batteries are a bit tricky to replace, the lamp is good deal for those looking for a nice looking emergency lamp for long term power outages.
It draws 340 mA at full brightness, which works out to almost exactly their claimed 100-hour life with two banks of 17,000 mAH batteries. At the dimmest setting it drew 112 mA, theoretically good for around 300 hours of life.It doesn't appear to have a sophisticated power supply - the lamp dims as the battery voltage drops, unlike some LED lights that regulate the voltage.
I read a review that said the &#34;batteries are awkward to install&#34; so I was scared about that part when this Lantern arrived. I have to say...nothing could be easier! The battery installation is incredibly intuitive and you could honestly just open this lantern and go based on how easy it is. Also, the light is incredibly white and bright and since it is LED and safe (as opposed to gas) it is the perfect emergency lamp or camping lantern.
I didn't buy this on Amazon (Costco $20) but had to write this review. We've spent a small fortune on all kinds of lanterns over the years with mantle(s), fluorescent and now LED that run on white gas, propane or batteries. All of them can exhaust their fuel, whatever it is, within 24-hours (continuous use), but this light is crazy-efficient with battery power. I installed 4-D rechargeable nicad batteries in it for 5 nights worth of camping.
Answer: yes
