Energizer Light Fusion LED Lantern Lightning Review: A Light for Every Emergency

Energizer Light Fusion LED Lantern Lightning Review: A Light for Every EmergencyIt's the middle of the night and you're in the middle of nowhere when—whumpa, whumpa, whumpa—you get a flat. Rather than fumble through the tire change in the dark, why not keep this portable LED lantern in the boot should the need arise?

What Is It?

A 300-lumen area light from Energizer's Light Fusion Technology line.

Who's it For?

Backpackers and campers looking for an alternative to bulky and explosive propane lanterns, DIY mechanics tired of singeing themselves on white-hot drop lights.

Design

A radical departure from the conventional gas lanterns you took camping as a kid (looking at you, Coleman), the dimmable 300-lumen LED light source spreads evenly across a roughly 4.5-inch square translucent fold-out plate hinged at the unit's top rubberized handle. An integrated kickstand flips out from the opposite end of the case (which houses the AA batteries under a locking cover plate) just below the power switch.

Using It

This lantern only has two moving parts: the lamp plate and the kickstand. Extend both of these, press the power button, and boom—illumination.

The Best Part

This lamp runs forever. Even at maximum brightness, it lasted 6 hours with eight NiMH 1.2V, 3 hours with eight 1.5V alkalines, 3.5 hours with four NiMH 1.2V, and 1.5 hours with four 1.5V alkalines. Lowering the brightness, which at full power gets a bit glarey anyway, dramatically extends its run-time.

Tragic Flaw

The battery compartment cover is secured by a pair of quarter-turn plastic screws that cannot be opened by hand. You'll need a flat head screwdriver to release them, though nickles work in a pinch.

This Is Weird...

The lantern accepts batteries in sets of four or eight. This doesn't affect the brightness, only the runtime.

Test Notes

  • It's got an IPX4 water resistance rating meaning it can endure minor splashes and downpours but can't be submerged
  • Press and hold the power button to dim, press and hold again to brighten. The lamp will blink in shortening intervals as it gets really low on power.
  • The lantern can use both disposable alkaline and rechargable NiMH batteries

Should You Buy It?

Yes. It's only $35, runs on the most common battery size, and is small enough to stash in a car trunk or go-bag. It's a sensible, low cost, long-lasting solution to emergency lighting, what more do you want?

SES demos first Ultra HD transmission in more efficient HEVC standard

SES demos first Ultra HD transmission in more efficient HEVC standard

We're still a bit away from Ultra HD becoming the standard for television. One of the things standing in the way is just how much bandwidth pushing that many pixels demands. SES recently demonstrated an Ultra HD transmission that uses the up and coming HEVC (High Efficiency Video Coding) standard, as opposed to the more established H.264. It's demonstrated 4K broadcasts before, as seen above at its IBC booth last year, but those were using older codecs. The 3,840 x 2,160 image was broadcast at a data rate of 20 Mbps, roughly a 50-percent improvement in encoding efficiency over H.264-based MPEG-4. The demonstration was performed with support from SES's partners, Harmonic and Broadcom, the latter of which provided the BCM7445-based decoding box used for pulling in the video. The tech still isn't quite ready for prime time, but we'd say a 4K House of Cards stream is probably closer than any of us realized.

Adapteva shows off production Parallella mini 'supercomputer' boards

Adapteva shows of its first production Parallella mini supercomputer boards

With its ambitious Parallella computing project funded on Kickstarter since last October, Adapteva's now showing off its first mass-production boards. These Raspberry Pi-esque devices are capable of supercomputer-like parallel computing performance thanks to power-sipping Epiphany multi-core accelerators. As proposed, both the $99 13GHz 16-core (26 gigaflops) and $199 45GHz 64-core accelerator (90 gigaflops) variants make an appearance in the pictures. The company is tweaking this initial batch of 10 to test various functionalities, with its current update noting that getting Linux to boot off the boards is the next step in testing. Final units are still slated to arrive on doorsteps during the summer, and hardware schematics will eventually be available as open source-info -- after all, the Parallella has always been pitched as an open undertaking. Those enthused by circuits and the boards they live on will find a path to more info at the source link.

DARPA flaunts HD heat vision camera small enough to carry into battle

DARPA thermal camera

Thermal imaging cameras are highly useful tools for military and law enforcement types, letting them see humans inside buildings or land a helicopter in the fog. High-definition models are too heavy for servicemen to tote, however, so DARPA and a private partner have built a 1,280 x 720 LIWR (long-wave infrared) imager with pixels a mere five microns in diameter. That's smaller than infrared light's wavelength, allowing for a slighter device without giving up any resolution or sensitivity while costing much less, to boot. Researchers say that three functional prototypes have performed as well as much larger models, allowing them to see through a simulated dust storm, among other tests. If DARPA ever lets such goodies fall into civvy hands, count us in -- you can never have too much security.

Facebook launches real-time graphs to highlight its data center efficiency

Curious as to the effect that your poking wars are having on the planet? Facebook is outing power and water usage data for its Oregon and North Carolina data centers to show off its sustainability chops. The information is updated in near-real time, and the company will add its Swedish facility to the charts as soon as it's built. The stats for the Forest City, NC plant show a very efficient power usage effectiveness ratio of 1.09 -- thanks, in part, to that balmy (North) Carolina air.
