Wish-Lust: ZyntonyRa light Strips

Ok, I was contacted by the people from Zyntony, who had launched a bad-assed light Kickstarter, and not had it make its threshold,  but they are back with a brand new product, that has already surpassed it's threshold, by 287% at time of writing, but I wanted to give them some more bandwidth with the info from their press-release.

Their new offering, the Zyntony Ra is a game-changing light for outdoor adventure enthusiasts that is designed to light up the entire area around you instead of just a spot in front of you.

At full power, Ra puts out 800 lumens of warm natural light. A pair of Ra attached to the shoulder straps of a backpack boast a staggering 1,600 lumens of light creating a “zone of daylight” around the wearer. “This is brighter than ten good headlamps”, one of the founders exclaimed in their release. He continued: “We named the light Ra after the Egyptian god who carries the sun across the sky because carrying one of these lights is like carrying a piece of the sun with you.”

I've covered similar strip lighting projects before, in the PackLight but the Ra is a step beyond.

Multiple mounting options enable Ra to be attached almost anywhere. The user can fix it to any ferrous object using the built-in rare-earth magnets. Ra can be attached to nearly any article of clothing using the accompanying magnetic backer strip, just by slipping the backer-strip under the outer-layer of clothing, and the Ra snaps into place magnetically. Using the D-ring strap and simple hook and loop ties, Ra can be fastened to virtually any piece of gear.

Each of the emitters can put out well over 500 lumens each. So in theory, the light could put out over 2,500 lumens. However, they are only running them at slightly over 1/4 power. Zyntony state they do this for several reasons:

First, is that the emitters are way more efficient - (in that they have a much higher lumens-per-watt output) at lower power. This means that you get a brighter light and longer battery life compared to a light that only has one or two emitters.

Second, by running them at lower power, their life is significantly extended to the point that they will virtually last forever (immortal buyers beware...).

Third, multiple emitters allow for each one to have a separate light dispersion pattern. This allows a less complex and more cost-effective way to balance light spread vs. throw, especially good given its area-effect design principle.

And fourth, by having multiple emitters running at lower power, you can spread out your heat dissipation, also especially useful if you're wearing it.


Ra is powered via a micro-USB input. Zyntony makes four different sizes of battery packs allowing the flexibility to carry just the power you need or as much as you want.

The Ra is designed to be lightweight to facilitate attaching it wherever you want so there is no internal power. It must be powered via USB. By connecting to a power pack via the USB, Ra has the flexibility where you can select a small BatPak for just the power you need or a larger one for as much power as you want. And you can connect up to three Ra's to BatPak II, BatPak III and BatPak IV. That flexibility supports a lot of different mounting options.

Zyntony are planning to certify the Ra to IPX7 which means it is submersible to 1 meter. It will certainly withstand the rain. The USB ports are the biggest challenge they are facing in this but by planning to use rubber boots/escutcheons on both Ra and the BatPaks, it should be waterproof as long as you use the Zyntony USB cable and power pack.

I'm really looking forwards to seeing what they can do when I get a set in-hand, but for mow, their on my wish-lust list!

Review: UVPaqlite - Mule Light Orb

As first published on BreachBangClear!


I do so love my glowing lights. There is something very satisfying about a renewable light source that is charged by the sun to mark out the dark corners of a room, locate a bag or device in the dark or even to ID friends vs foes. I have gathered quite a collection of glow in the dark items over the years, all starting with those little stars you put on the ceiling to make constellations, as a kid. My girls have them too, now.

I've been an even bigger fan of the products from UV PaqLite for some time, I keep them in my packs, hand them to my kids when we go out at night and generally have them on hand for those "where did everybody go moments, where I might need more than just one of my multitude of flashlights.

One is none, two is one, and batteries run low. I kept tabs on the family team of Steve Nagel and Alexis Nagel, and their inspiration, gun-toting outdoors-man Uncle Vernon, who was their inspiration. Their basic product is based around the fact that if you embed the raw strontium aluminate crystals in a solid resin you get a long glowing light-source, in a solid, stable and resilient unit.

The problem with all this type of glow-in-the dark products are that they all still need to be charged to work. If your emergency happens when you're already in the dark, or the light is in the bottom of a bag, you are not going to get much use from them. This is where the folks from UVPaqlite came up with another option. They embedded a LED in the middle of two halves, with USB rechargable lithium ion rechargeable batteries, light-detection sensors and some clever circuitry to give you a hybrid light that gives you an infinitely renewable GITD shell and long lasting electronics that can hold 100hours of illumination on a single charge.
So the UVPaqLite people have came up with a hybrid model.

To operate the flashlight mode, you press the button built into the middle band. This illuminates one side of the orb, right through the embedded crystals, and casts a very satisfying light, as well as charging up the GITD crystals. Holding the button until the light flashes sets a timer mode, which will set the LED's on either side of the orb to flash every two minutes recharging the crystals to peak performance. The batteries will hold around 100 hours of these flashes.

An even smarter feature utilizes a small photo-receptor built into the side of the Orb, just beside the USB charge port.
 Holding the on-off button for a double-flash of the light letting you know you've activated the light sensor and now the Orb will only function in hybrid mode when it’s dark. It lights up for about 4 seconds, which can be a bit disconcerting if you're trying to get to sleep and it's dangling over your head. This means you can set it up wherever you want it and forget about it. Clip it to the side of your pack with the built in split ring and snap-clip, hang it from the top of your tent, or drop it in your bag.

 It will self-charge the crystals as you go about your life. This is really good for the forgetful or the over-packed.

The on-theme USB cable they supply is just long enough to do the job and not so much to get in the way. The 45g (1.5 oz) Orb is  37mm (1.4") x 25mm (1") is a little big for a key-fob, but perfect for pockets. I've had it on the side of my Hazard4 Escape RG harness for a while and didn't find it getting in my way at all.

It's weather-resistant in its native state, meaning it can take some rain and exposure, but don't soak it. If you're expecting a big wet, they've thought of that too. The dive capsule is rated to 100m (300') which is more than three times the depth I've ever been rated to SCUBA dive to, but I suppose some day I might want to tag some salvage and come back to it with a ROV. 

I'm a lot more likely to be yomping through a storm though, so the extra weather protection and night-swimming illumination is what appeals to me. You can't access the button from inside the capsule, so whatever setting you have selected before you hit the water is what you're stuck with, unless you feel brave enough to pop it open in the wet. In the capsule the Orb is positively buoyant and floats around happily on an even keel. It's a well designed accessory, with a smooth threading action, and a sturdy o-ring and flat-folding attachment ring.


I was really impressed with both the GITD illumination that the Orb offered, and the flashlight mode. It certainly has a lot of potential to give medium term, renewable and reusable illumination, on-demand, really the best of both worlds. Since getting my hands on the UVPaqlite range I haven't used a cylume stick, but I've kept some around just in case I've been caught out without an immediate light source and now that I have the Orb, I might just pass them off to the kids to have one last hurrah.

Review: Going Solar!

When the going gets rough, and the lights flicker out, we will want to power and run our gadgets and drive back the night with the familiar glow of electric lights. I've been collecting solar chargers for a while now, and I thought I would give you a quick review of them.

First up is the B-Squares Modular Solar Electronics which I backed on Kickstarter. This allows the user, in theory, to run a USB outputting rechargeable triple AAA charger, a set of LED lights, or a iPhone charger. The single solar square generates 0.325W of power, which is enough to run the LED's, charge the batteries or run the iPhone. Or at least, it's supposed to. I have had little or no luck with it, and am afraid to say I've been very disappointed with this device. 

 The second of these devices is the original Solio Universal charger which is a mains-capable charger, with a battery pack. It folds out into a tri-leaved floret  is capable of output ranges from 1.5 to 5W, the internal rechargeable battery has a capacity of of 3.7V 1000mAh. It comes with a variety of output ends for the included cables and will even charge iPhones via a USB output. One cool feature of this is that it can be orientated by feeding a pencil through the central hole, propping it up to achieve maximum solar  contact. I've been very happy with this device, and take it camping and adventuring with me frequently.

Lastly is the solar charger that came with another Kickstarter project, the Packlights which I have previously reviewed. I delightful sweetener to their deal was the inclusion of these purpose built charger and battery packs. Also mains-chargeable, these these packs generate  0.77W at a Voltage of 5.25 +- 5% and the internal battery has a capacity of 2200mA with an output of 5.6V at a maximum current of 600mA. It includes a USB output, and both a bright LED light, and a dim LED charge indicator. Another interesting feature is that they give estimated times for charging, which are: by Solar Charge:10-14 hours depending on lighting & weather conditions and by DC Charge: 2-3 hours where the charging current: 140mA (per hour). This is a really nice package, and I'm very glad i acquired two of them. They fit nicely stowed into one of the Platatac FUP pouches so I can imagine wearing them out in the field, ready to recharge my tech.
