I'm a flashaholic and found these and wrote a gear review article about them for GunNews Magazine late last year.
Hope you find it helpful and interesting.

New lanterns are a quantum leap forward
Lanterns, new and old. From left, the new AA lamp, the D-cell lamp, an incandescent 6v lantern and a propane monster. The Garand bayonet on the bottom is for scale. Yes, my bathtub is clean.(GunNews Magazine) - Emergency / camping lanterns have made a quantum leap forward thanks to recent advances in LED lighting technology. Today’s recreational campers can purchase a very bright, long-lasting lantern that weighs a fraction of the propane lantern that we and our parents have used for decades. Today’s lantern is safer, smaller, quieter to use.
Ray-o-Vac has released a pair of CREE-equipped lanterns for campers and those wishing to have a safe and effective light in case of an emergency power outage in their home.
The CREE LED is a recent improvement in LED technology that burns bright while sipping battery current. These Ray-o-Vac units have numerous useful features including both “high” and “low” settings, clips on the bottom to hang them in a tent and a readily removable globe for virtually omnidirectional lighting.
The AA-powered unit (less than $20 at Farm and Fleet) weighs in, loaded with alkaline batteries at 7.6 ounces. Ray-o-Vac brags that it emits 70 lumens on its highest setting and will run on its “low” output for up to three days. Reading was not at all difficult with this unit operating on low when placed next to the book.
The D-powered version (about $30 at Farm and Fleet) is substantially heavier with batteries at 1 pound, 13.8 ounces, according to Pitney Bowes. Ray-o-Vac claims it has a 300 lumen output on high, and will run for 150 hours on “low”.
The old dual-mantle propane lantern (which goes for about $30 at many retailers) weighs in at 4 pounds, 5.5 ounces (minus the base ring) and offers adjustable brightness and will run for up to 8-hours on a reduced setting. My Coleman gas lantern, running at full-tilt, emitted about as much light as the D-cell LED Ray-o-Vac, albeit a much warmer color.
The great advantage of these new LED lanterns is their size, weight, burn time, safety and cost of use. With propane cans running nearly $3 they are comparable to the cost of a trio of alkaline batteries, however the battery powered lantern will last days, not hours like the incandescent battery lanterns and D-cell batteries are much smaller and safer to transport than propane bottles. There is no risk of fire, carbon monoxide poisoning or burns with the LEDs, which can be used safely inside a tent or home for extended periods of time.
So, regardless if you’re a weekend warrior at the campground or just wishing to be prudent about having some backup lighting in case of power outages or emergencies, check out these Ray-o-Vac lanterns at your local Farm and Fleet or Ace Hardware.
