It’s waterproof to IPX-8 Standard (1.5 meters) and impact resistant to 1.5 meters.

The Nitecore EA81 is available on Amazon for about $280.

The Brightest Keychain Flashlight: Titan Plus

Surefire has released the Titan Plus, a keychain flashlight that produces 300 lumens in its highest light mode. Before this release, the brightest keychain light produced about 80-120 lumens, so this threefold increase is significant.

I’ve purchased this light and will be testing it soon. The 300-lumen mode lasts about 1 hour using a AAA Ni-MH battery.

All Surefire flashlights are designed and built in the USA, although some components are still sourced outside the US. Surefire says:

We do import a few components – most notably, the finest light emitting diodes (LEDs) from top-notch manufacturers outside the country – to incorporate into our products. All of that said, we do rely on as many American-made parts and components as possible, and the assembly of these components is done under our watchful eye in the U.S. to ensure optimal quality.

The Titan Plus is available from Amazon for about $81.

Best Design: The Z-Bar Mini LED Desk Lamp

The slender Z-Bar High Power LED Desk Lamp features high-tech power-saving LED bulbs in a minimalist frame. With its angular black aluminum housing and unique pivot, it belongs on a Berlin engineer’s desk or in the lobby of an upscale New York architect.

The ingenious design extends beyond aesthetics; this is a seriously bright light that uses very little energy. The Z-Bar’s six daylight white LEDs generate about 240 lumens of light and only expends 9 watts of energy.

If 9 watts is still too much energy usage for your taste, activate the built-in 4-step dimming function to produce a softer light for even less wattage. This feature works incredibly well when you are unwinding prior to bedtime. Lower the light before you fall asleep to adjust your brain to get ready for bed.

The thin circular base is weighted to keep the light from tipping over, and adjustable joints can be placed in almost any position without tightening or loosening knobs or screws, simply move the light to where you need it and the lamp will hold to form.

The Z-Bar is the winner of I.D. Magazine “best of category” award. It is available on Amazon for around $300.

• EBL 3.7V Li-ion Rechargeable Batteries — 3000 mAh
• Kiminors 3.7V 18650 Rechargeable Battery — 3200 mAh

Our recommended 18650 battery charger: XTAR VC2

About 18650 Batteries

What are the advantages of 18650 batteries? They are 3.7-volt lithium-ion batteries that can be recharged and are compatible with a wide range of electronics, including laptops, digital cameras, flashlights, and even electric car batteries.

Panasonic, Sanyo, Samsung, and LG are the top level 18650 cell manufacturers, making long lasting cells in a standard size (18 mm by 65 mm) that fits all 18650 compatible devices. Chinese knockoffs are available for cheaper but are prone to shorter lifespans and aren’t always uniform in size. As a rule, be wary of “protected” 18650 batteries, which have small circuit boards at the bottom that do not fit some electronics, such as flashlights.

High-drain batteries are safer and designed for high current devices, such as vaporizers. They are also less wasteful, meaning they have a longer life cycle and can last for more recharges.

18650 Battery Chargers

The best part about 18650 batteries is that they can be recharged. That means you will need a reliable charger to keep them energized and in working order. I like the XTAR VC2 charger because it has an informative LCD screen display.

The LCD screen tells you the real mAh capacity of your batteries, so you can make sure they are getting the advertised amount of fill or identify when they are losing efficiency.

Brightest Bike Light: Niterider Pro 3600 Lumen Light

The Niterider 3600 Pro is a 3600 lumen light made in the USA. This light has two chambers, and each chamber contains three Cree XML LED bulbs.

Niterider have a great reputation, and I’ve found their lights to be very durable — they’ve survived a few falls onto pavement from my bike.

This light is very bright and projects a wide beam hundreds of feet. A unique feature of this light is the included DIY software, which allows you to customize the settings it to your needs.

Brightest Bike Light With Built In Battery

Note that the light’s beam is just too bright to use in an urban area, unless you greatly step down the intensity! If you feel you’ll be doing this, you might consider the 1800 Lumen Niterider or the 1200 lumen Niterider.

Almost every professional Christmas light installer uses conical LEDs for their displays. Conical LEDs are waterproof and snowproof because the LED is injected molded into the plastic cordage. Conical LEDs are also 25% brighter than an incandescent indoor Christmas light. The brightness comes from the intensity of the LEDs and the magnification of the conical lens.

The Details On Conical LED Lights

Overall, LED lights are a great choice for Christmas because the lights almost never fail, and they are impervious to freezing temperatures. They are also much more energy efficient than incandescent bulbs. For this reason you can string up to 40 sets of LEDs together, and plug them into a normal electrical socket.

Conical LEDs are not recommended for indoor use due to their intensity (M5 or C6 LEDs are a better choice inside).

Conical 5mm LEDs are available from Amazon.

Yes, they are finally available. However, only a few Chinese companies manufacture them. These batteries are AA and AAA rechargeable lithium polymer batteries that output 1.5 volts.

• Tenavolt Lithium-Ion AA Batteries (2775 mWh)
• Deeleepow Lithium-Ion AA Batteries (3400mWh)

Lithium-ion batteries normally operate at 3.7V per cell. The circuitry inside the cells reduces the voltage to 1.5 volts. The batteries have a capacity of 3400mWh, which matches Eneloop Pro (NiMH batteries with the highest capacity). Additionally, lithium-ion cells are lighter than NiMH cells.

Other Lithium-Ion Rechargeables

There are also some lithium-ion rechargeable batteries made for high-performance flashlights and cameras in these sizes: 18650 and CR123.

A single 18650 battery can replace two CR123A batteries, although at a lower voltage (but much higher amperage). However, the 18650 is a wider cell and will not fit into a flashlight designed strictly for the narrower CR123As. Most modern tactical LED lights are designed to use a single 18650 or two CR123As, but it’s best to check before buying. See our article on The Best 18650 Batteries for more information.

There are also numerous other types of lithium-ion batteries made for specific laptops and other electronic gadgets. There is currently no standard size for these lithium-ion cells.

• For well water or other problematic water, I recommend Big Berkey drip filters. These filters use a combination of ceramic and carbon block filtration. Overall, they are the least expensive type of filters to maintain.
• If you are only interest in a pitcher filter — this BWT filter will remove most contaminants
• If you are able to spend $1500 to $3000, “whole house” filters are the an inexpensive long terms option. These filters are installed at the pipe where the municipal water pipes enters your home. I recommend the whole house filter by Pure Effect.

The Contaminants You Want To Remove

Typically, you want to remove these contaminants from your water:

• Toxic metals (Lead, Mercury, Aluminium, Cadmium, Chromium, Copper, etc.)
• Additives (Chlorine, Chloramines, Fluoride)
• Chlorination By-Products (Trihalomethanes or THMs)
• VOCs and other Organic Compounds (Pesticides, Herbicides, Pharmaceuticals, Fuels)
• Bacteria and viruses (Giardia, Cryptosporidium, etc.)
• Radioactive substances (Radon and Uranium, etc.)

If you use municipal water, you will usually find these contaminants:

• Chlorine
• Chloramines
• Fluoride
• THMs (Trihalomethanes)
• VOCs (volatile organic compounds)

If you use well water, these are the most common contaminants you’ll find:

• Particulate matter (dirt, bits of leaves, etc.)
• Bacteria and viruses
• VOCs (volatile organic compounds)
• Radioactive substances

The Effectiveness Of Different Types Of Water Filters

Pitcher Filters

Pitcher-style filters such as Brita filters are inexpensive units, making them very popular with consumers. However, in the long term, they are actually one of the most expensive option. The filters cartridges require frequent replacement — the cost for 40 gallons is $7-10 each, or $130-$190 for 750 gallons.

Almost all pitcher-style filters use GAC or “granulated activated carbon” as the filtration medium. Typically, GAC is coconut husks that have been heated to a high temperature in the absence of oxygen and then granulated. These filters do remove some chlorine and hydrogen sulfide (rotten eggs odor) — but are not effective at removing VOCs, metals, pesticides or fluoride. Overall, they are not very effective water filters.

Faucet Filters

Filters that attach to your kitchen faucet are very similar to Pitcher Filters, but they do filter a little better than the pitcher-style filters. However, they have the same drawbacks — they are expensive to maintain and they do not remove many contaminants. You must replace filters every 100 gallons at $20-$40 each or $140-$180 for 700 gallons.

Colin Ingram, author of the The Drinking Water Book rates all faucet filters no higher than “Acceptable”.

Gravity-Fed Drip Filters

In my opinion, the best water filters are gravity-fed drip water filters. These filters are excellent at removing chlorine, chlorination by-products, fluoride, VOCs, pesticides, particulates and pharmaceuticals. These filters use “candle” type filters, which are widely available and can be customized to your specific filtration needs.

Gravity-fed filters require no electricity to operate — water is filtered as it drips from the upper chamber to the lower chamber. Because the water is filtered slowly, the filtration is much more effective than a faucet-mounted filter. Generally, slow filtration methods tend to be best.

Berkey is best-known drip filter manufacturer. They make good quality filters. You might also consider ProPur filters. Their latest filter, the ProOne G 2.0, will remove fluoride — including hydrofluorosilicic acid (few filters remove this contaminant).

These filters use carbon block filtration, which works by the process of adsorption (different than absorption). In this process, the carbon attracts certain contaminants at the molecular level, and the contaminants become attached to the surface of the carbon. Once the surface of the carbon is full, the filter must be thrown out and replaced. However, the ProPur filters can be periodically scrubbed, and thus reused for years.

These filter are certified to NSF/ANSI standards #42 (test for chlorine, taste, odor and particulates), NSF Standard #53 (tests for Cryptosporidium, Giardia, lead, VOCs and MTBE) and NSF Standard #61 (tests that toxins aren’t leached into water). They are manufactured in England.

Berkey filter are available from Amazon for about $300.

Overall Rating: Excellent

Reverse Osmosis Filters

Reverse Osmosis filters use a membrane which removes many contaminants from water. They are usually paired with a Granulated Activated Charcoal filter to remove chlorine. Most reverse osmosis filters are installed under the sink and have a holding tank. The semipermeable membrane separates many contaminates (which usually have a larger particle size that water) from the water and rejects a large amount of water in the process. The result is a waste of several gallons of water for every gallon filtered and many naturally occurring minerals (including calcium and magnesium) are also removed from the water.

However, they are quite effective filters, in terms of removing contaminants. However, they do not reduce VOCs or pesticides (unless a Carbon Block filter is included). They can take up to an hour to filter one gallon of water and the filters need to be replaced regularly.

If you want to go this route, I recommend the iSpring Reverse Osmosis System, which is quite reliable.

Overall Rating: Very Good

Countertop Distillers

Countertop distillers are effective water purifiers, but they take some time to distill water (for example 5 hours to distill 1 gallon). They also require electricity to run, and they give off some heat and the integrated fans make some noise. Also, most distillers do not remove VOCs (like benzene) because they have a lower boiling point that water. So they will vaporize together with the stream, resulting in a contaminated distillate.

Countertop distiller that get a rating of “Excellent” from Colin Ingram in the The Drinking Water Book are: Megahome Countertop Distiller, Waterwise 4000 and Waterwise 8800, Kenmore 34480 and Pure Water Mini-Classic.

Megahome Countertop Water Distiller

This distiller is sold under many brand names — it’s the most widely distributed distiller in the world. It has many quality components despite being inexpensive. It produces 1 gallon of water in 5 hours. The water is passed through a small granular carbon filter. There’s a sealed connections from the distiller to the water collection container, so there is minimal risk of contamination by air. The unit has a stainless steel boiling chamber that is easily accessible for cleaning.

The Megahome Countertop Distiller is available from Amazon for about $150.

Waterwise 4000 Countertop Distiller

This is a more powerful version of the distiller listed above. It has the same features but produces 1 gallon of distilled water in 4 hours. Also received an “Excellent” rating from Colin Ingram in the The Drinking Water Book.

The Waterwise 4000 is available from Amazon for about $320.

Overall Rating: Excellent

Panasonic’s Eneloop Pro AA Batteries.

These are made with Nickel-Metal Hydride (NiMH) chemistry and have low standard discharge, meaning they can hold a charge for years.

AmazonBasics AA High-Capacity Rechargeable Batteries are a reliable low-cost alternative. They are about 30% cheaper than Panasonic cells, but last only 75% as long per charge.

The Details

Panasonic eneloop pro batteries are high-capacity lower-cycle AA battery popular with electronics reviewers and photography enthusiasts. First launched back in 2006, Sanyo eneloop batteries (since acquired by Panasonic) use eco-friendly NiMH cells designed for use with a wide-variety of products, ranging from flashlights to cameras. Up until the eneloop’s debut, rechargeable batteries were prohibitively expensive and couldn’t hold a charge for anywhere near the length of their alkaline competitors.

Eneloop changed that, but still lacked a little when compared to alkaline batteries or newer competitors. Panasonic’s upgraded option, eneloop pro, can maintain a charge for an extended period of time, with a capacity of 2,550 mAh and Low Self Discharge (LSD) technology. LSD tech is thanks to a highly-durable super lattice alloy that prolongs battery life with increased hydrogen stability that leads a stable voltage output and reduced self-discharge. Expect an eneloop pro to still have 85% of its charge after a year and 70% of its charge for ten years.

What really sets eneloop pro apart is the increased performance in high drain devices, such as DSLR cameras and ultra-bright flashlights. Eneloop pro lasts longer and omits more power in these high power consumption devices when compared to similar NiMH rechargeable batteries on the market. Simply put, these are the best choice for photographers and survivalists.

The added power comes at a payoff, however. Eneloop Pro batteries are among the most expensive NiMH batteries on the market, and last for fewer lifetime charges. Panasonic estimates that an eneloop pro can be recharged 500 times, but number is even lower in reality. Compare that to Powerex’s Imedion AA, which boast 1000 recharges.

Another Option

AmazonBasics offers pre-charged high-capacity NiMH batteries for an affordable price. They are rated at 2400mAh, giving them a longer run-time than similarly priced competitors. They are ideal for everyday uses in low drain devices, like TV remotes and electronic alarm clocks.

Wirecutter found that AmazonBasics did not perform as well in high power devices, such as flashlights and digital cameras.
