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.

Currently, the best rechargeable C-size battery is the ELB 5000 Battery. A pack of 6 costs $24.

About C-Size Batteries

Although they are no longer as popular as they used to be, C-size batteries are one of the most common alkaline batteries today. They have kept the same dimensions (50 millimeters by 26.2 millimeters) since 1926 and are used in medium-drain electronics such as toys and instruments. Disposable 1.5V alkaline dominated the C battery market for years due to its high capacity and long shelf life.

Rechargeable C-size batteries are rapidly gaining marketshare over their throw-away counterparts, thanks to crucial technological advances within the past decade. Instead of alkaline, they are using 1.2V Nickel-Metal Hydride Chemistry (NiMH) that allows for greater capacity that doesn’t atrophy after long stretches of inactivity. Whereas in the past rechargeable batteries would drain by themselves via discharge even when they weren’t in use, they now retain up to 85% of their charge capacity for months at a time. No more pulling out a rarely used flashlight the night before a camping trip only to find that the charge has evaporated in your garage.

Of all the rechargeable batteries on the market, ELB offers the best C-size battery. The 1.2V NiMH cells have a 5000mAh capacity, almost as much as the standard 8000mAh of disposable alkaline batteries and much higher than other NiMH cells, and close to the capacity of a lithium cell.

For a charger, I recommend the Maha PowerEx MH-C808M. This smart device can charge 9 C-size batteries at a time.

The softest merino shirt I’ve tried is the Outlier Ultrafine T-Shirt. The fiber used in this shirt feels almost buttery to the touch. It has a excellent drape too, due to the use of 17.5 micro merino fibers.

Merino has the ability to draw moisture into the very core of the fiber. This pulls moisture away from your skin. It also allows the fabric to keep breathing if it gets wet. As the temperature cools the natural crimps in the fabric insulate you.

Outlier constructs their shirts in Brooklyn, using merino from New Zealand. The company says this about the wool:

We use a Mackenzie 17.5, 195gsm Merino Jersey who’s name stems from the Mackenzie Basin on New Zealand’s South Island, where the bulk (but not all) of the merino used is sourced. It’s all non-mulesed, farm traceable and certified by AsureQuality. More importantly though the merino is a tight spectrum, low variance, top capped fiber blend. Generally merino micron numbers are generated by averaging a mix of various micron fibers. This means a standard 17.5 micron fabric will actually include much larger fibers in the mix. The Mackenzie blend is tight spectrum and low variance to create a more consistent and precise yarn. More importantly the Mackenzie 17.5 is top capped at 17.5 microns, there are no larger fibers making it a softer and smoother fabric, and in fact the yarns and fabric actually average a number lower than 17.5 micron.

The Best Waterproof Bluetooth Speaker: Ultimate Ears UE Boom 2

Pros: Waterproof, rugged, great battery life, impressive sound, lightweight

Cons: playback controls occasionally unresponsive

A favorite pick of top tech magazines, the UE Boom 2 is a remake of the popular, original UE Boom.  Although just over 1 lb., the compact, cylindrical speaker projects a loud, clear sound with deep bass in all directions.  Unlike many delicate tech gadgets, these speakers were meant to be taken outside – the outer shell is resilient, rugged and made to withstand dings and dents.  It’s not just water-resistant – it’s waterproof – and can be submerged in over three feet of water for up to 30 minutes.  The rechargeable battery lasts an impressive 15 hours, perfect for a weekend camping trip with a group of friends.  The UE Boom 2 also offers a variety of other features, including the ability to sync with a second UE speaker for even more sound, intuitive app features, and a variety of color options to suit any style.

The UE Boom 2 is available at Amazon for around $200.

The Best Bluetooth Speaker for Sound Quality: FUGOO

Pros: Powerful sound, excellent battery life, durable design, customizable “jackets”

Cons:  Does not give visual cues on volume or battery life, changing jackets requires some dis-assembly

According to TechRadar, the FUGOO Bluetooth speaker is one of the industry’s best-kept secrets.  Although some high-end Bluetooth speakers from well-known brands, such as Bowers & Wilkins, Bang & Olufsen, Sony, Marshall Kilburn, and Bose, may boast of higher quality sound, many of these are not realistically portable, or likely to be used as portable speakers, due to their size, weight, and price tag.  However, the FUGOO is a true portable speaker at a little under 1.5 pounds, and includes a durable core and different exterior “jackets” depending on the purpose and environment.  Specifically, the core is itself a rugged machine capable of handling dings, dents, and spills.  The “style” jacket offers additional protection and a streamlined silhouette.  The “sport” and “tough” jackets offer additional protection.  The speaker sound is exceptional; music lovers will be astounded by the depth and clarity of the sound produced via its six drivers, including two tweeters, two mid/sub drivers, and two passive radiators.  The FUGOO also offers an unbelievable 40 hours of continuous battery life.

The FUGOO does have some small drawbacks.  Its streamlined, minimal visual design only indicates whether the machine is turned on or off.  All other cues are voice-activated, which means a simple glance to check the volume level or battery life is not possible.  Additionally, the jackets are not easily interchangeable.  Although the “style” jacket slides and locks in, the other jackets require a little more assembly; many reviews noted changing jackets was frustrating and somewhat confusing.

The FUGOO Bluetooth speaker is available on Amazon for $178 to $230, depending on jacket type.

This headlamp weighs just 1.1 oz (32 grams), or 2.9 oz (80 grams) with an AA battery and headband. This makes it a great choice for a runner or night hiker.

In most cases, you’ll want to use the 116-lumen “medium” mode — this is quite sufficient to light up a trail at night. The Zebralight H52 lasts about three hours in this mode, when using a rechargeable NiMH batteries like the Eneloop Pro. The headlamp is also capable of accepting a 3.7V 14500 lithium-ion rechargeable battery.

When in high mode (300 lumens mode) it lasts about 40 minutes. In low mode it outputs 27 lumens — this enough light to read a book in bed for example.

The maximum beam length is 66 meters.

The Zebralight H52 is waterproof to IPX7 — this means it can be submersed for 30 minutes at a depth of 1 meter. This is due to its unibody aluminum casing.

Here are some more nice features on this headlamp:

• A battery capacity indicator (LED flashes 1-4 times)
• Automatic stepping down to lower output when battery (AA and 14500) capacity is low
• Over-discharging protection for 14500 batteries at 2.8V cutoff

You can find the Zebralight H52 (Cool White). on Amazon for about $74. Also available is the 280 lumen Neutral White (this version has 20 fewer lumens but a slightly warmed light).

A cordless vacuum is a useful and convenient device — if it is designed correctly. In the past I’ve had experience with small cordless vacuums that I used to clean my car. However, these cheap devices all seemed to suck — because they didn’t suck.

I read some reviews on the latest cordless vacuum offerings, and several reviewer recommended the cord-free Dyson vacuums. I went ahead and bought a Dyson V6 Motor Head for testing purposes. I used this vacuum in my home for about nine months.

I really wanted to like the Dyson Motor Head there were several problems with it:

• It was really difficult to remove the dust canister from the vacuum, and even more difficult to put it back on
• The vacuum was too noisy– I ended up wearing some protective ear muffs while vacuuming
• The vacuum would often turn off, due to dust getting jammed in the intake valve
• The vacuum’s battery life was adequate, but could have been better

Basically, I started looking for a new cordless vacuum, because I was done with this offering from Dyson. However, I couldn’t find any good substitutes. Then I noticed that Dyson had released a newer version of their vacuum — the Dyson V8 Absolute. This vacuum seem to address all the problems I had encountered with Dyson Motorhead:

• They fixed the emptying mechanism — the Dyson Absolute only requires a single press of a button to open the vacuum canister and empty the dust inside
• The vacuum makes much less noise, even on “turbo mode” — there’s no need for protective head gear now!
• The vacuum doesn’t turn off randomly due to dust clogging — it only seems to turn off when it’s actually full of dust
• The battery life is much improved — I can easily vacuum all the floors in my house without needing a recharge

With all these improvements, Dyson has now created a cordless vacuum worthy or their brand.

I’ve come to enjoy vacuuming now — having a cordless device really does make this chore easier. I’m also more inclined to grab the vacuum more often since it’s so convenient. I just wish Dyson had got it right the first time!

You can buy the Dyson V8 Absolute Cord-Free Vacuum on Amazon for about $550.

USB Thumb Drives use flash memory to store and transfer data. These little guys have been around for awhile, and are a quick and effective means of transferring data. There are a couple factors to keep in mind when purchasing a USB thumb drive. The first is speed. The era of slow-as-molasses thumb drives is gone but not forgotten, and many of today’s USB 3.0 drives still leave something to be desired.

You also want a drive with encryption. The sad truth is that USB drives are easy to lose, especially if you use shared computers. Get a device that can encrypt your files so strangers can’t access them if they find your drive.

Finally, you want a durable device. While the exact level of ruggedness you want may vary, make sure to get a well constructed product that doesn’t overheat or jam up in a slide.

The Best Overall Thumb Drive: SanDisk Extreme CZ80 64GB

For the pasts few years, California-based SanDisk has produced the best USB 3.0 thumb drive. Their 64GB Extreme CZ80 is fast, affordable, and secure.

This drive delivers read and write speeds at a significantly faster clip than most competitors. SanDisk advertises read speeds up to 245MBs and write speeds of 190MBs, and user benchmarks confirm that these speeds are mostly accurate. This means you can transfer a full-length SD movie in about 10 seconds. That’s 50x faster than old USB 2.0 drives (and double the speed of many 3.0 drives). This drive is ideal for transferring large files, both due to its capacity and speed relative to other options on the market.

The drive also protects your files with AES 128-bit encryption and a secure access vault that works on both Macs and USB. It also includes RescuePRO data recovery software. The Extreme is made with durable plastic, not the most rugged USB drive on the market, but it is solidly constructed and comes with a limited lifetime warranty. It’s also not the most discrete, coming in at 2.8 inches long. But the speed and value of this device cannot be beat for most users.

The Fastest USB Thumb Drive: Lexar 128GB JumpDrive P20

USB drives get a bum rap for their slow speeds. Earlier models had read and write speeds in the low teens, while even many of today’s USB 3.0 drives take twice as long as an external hard drive. But the Lexar 128GB Jump Drive P20 delivers an impressive read/write speed of 400/270MBs. That speed is fast enough to transfer an HD movie in less than the time it takes a Netflix video to load and buffer.

The JumpDrive P20 is housed in a sturdy metal alloy case with a glossy black mirror finish. It’s a retractable drive, which made me suspicious at first, as retractable drives are prone to jamming or otherwise breaking. But the P20 slides along solidly (if not a little stiff) and is protected by a lock mechanism that keeps it safe when extended. At 25 grams, it has a nice heft to it. Lexar includes a limited lifetime warranty. I also like the 256-bit AES encryption via EncryptStickTM Lite software.

The main draw is the drive’s USB 3.0 capacity. This drive runs faster than many external HDDs. While it doesn’t touch SSD speeds, it gets the job done fast enough to be a viable option for large data transfers. Transfer 1000 photos in 1 minute 15 seconds or a full-length HD movie in 36 seconds.

The Most Secure USB Thumb Drive: Apricorn Aegis Secure

The Apricorn Aegis Secure Key is the perfect storage device for a small amount of data. There are two steps to protect your data. First, it requires you to enter a 7-15 digit code on an alphanumeric keyboard.

The second layer of security comes from 256-bit AES Military Grade Hardware Encryption. The Secure Key is tested by the National Institute of Standards and Technology and receives a FIPS 140-2 Level 3 cryptography specification. It doesn’t need any software or firmware to run. That means there’s no risk of a firmware hack. Finally, it protects against brute force attacks with a mechanism that deletes the encryption key if an incorrect PIN is entered too many times.

You can set up an Admin PIN as well as individual user PINs, so companies can recycle the keys if they are granted to new users. The keypad is powered by a battery and is convenient to use. It also resits dust and water ingress. The rest of the device is also solidly constructed in water-resistant aluminum casing. This version uses USB 2.0. A USB 3.0 version exists, but has a few issues (like overheating) that this version doesn’t have.
