The Lumedyne X Flash Recycle Accelerator for Canon is an innovative way to power your flash while halving its recycling time and doubling the battery life of the flash's on-board AAs.

Due to its extremely light weight, small size and lithium battery, it's hard to call the X a battery pack. Lumedyne opts instead for calling it a "recycling accelerator" which partially explains how it functions. The X plugs into the HV input on your compatible Canon flash, completely bypassing the electronic functions of the flash like the LCD display etc. Instead it goes straight for the "engine room" boosting your flash's recycling and filling of its capacitors. While other products that use several AA batteries operate on the same principle, the X does it in a bantam 0.6 by 1.7 by 2.8" form factor that weighs only 2.7 oz, while multiple battery solutions weigh at least 1.0 lb and require a cable that, as we all know, is a real annoyance when flipping from vertical to horizontal compositions.

The X's battery fully recharges from depletion in about 3 hours. Since it's chemically composed of lithium-ion, it doesn't have a memory, allowing "topping up" of power before it's exhausted. The battery is good for 500 cycles (charges) or about 2 years. It is replaced free of charge if the capacity has dropped 25% before that time. Charge level is displayed by pressing a button that lets you know when it's down to 1/3 charge.

The X comes with a dual USB-style international AC Charger and a dual USB-style vehicle charger both rated for up to an amp each in output. Long and short USB MICRO-B cables are also included.

The X Factor

The X makes your on-camera flash recycle about twice as fast as normal with any power setting or mode. AA batteries only have to do about half of the recycle work and last twice as long

Small and Light

The X measures only 0.6 x 1.7 x 2.8" and weighs just 2.7 oz

Innovative Technology

Not a conventional battery pack, the X allows your flash's electronics such as the LCD display to be powered by its own AAs, while the X helps recycle and fill the capacitors directly

Lumedyne X Flash Recycle Accelerator Reviews

A flawed concept

By gv

The specs say that the unit has a 500 times recharge life, the same re-charge life as Eneloop AA's. So for the sake of lighter weight and no cable, you're paying $ and then you have to replace it in time. A flawed concept, when the excellent, proven Nikon SD-9 is a lifetime investment for $ with a few bucks for battery replacements when their recharge time is over.

Performs like a Mini Cycler

Have the Lumedyne X and love it performs much like a mimi cycler for speedlights. Very small and compact and plugs directly into the flash so no cords to get tangled in. Performs as advertised doubles the life of the onboard batteries and cuts the recycle time in half. Not as fast as the big belt cyclers on full flash dumps but with higher ISO and TTL use you may not notice any difference. The X also maintains the flash capacitors at full charge for more consistent results. Normally the capacitors loose some of their charge before topping off again from the onboard batteries. Performs very different and better than the cheep Chinese extra batteries that only extend battery time but do nothing to speed up the recycle time of the flash. Save your money and get the Lumedyne X it's a much more useful and a real photographers tool. Once you get used to using the X or a Cycler and your flash fires every time at the correct intensity it's hard to settle for the basic performance and missed shots that the onboard batteries alone provide. I find that the Lumedyne X now lives in my camera bag as a light weight alternative to a cycler battery pack. It's great to have cycler performance at hand without the weight penalty of dragging it around if you don't need it or use it. Great for traveling less stuff, less weight! I'm a professional wedding photographer and found the Lumedyne X to be a great and useful addition to my bag. Very handy when dealing with two bodies, no tangled cycler cords. Also love the USB charger that lets me recharge in the car between locations. Lumedyne, is also a great company that really stands behind it's products that are made in the USA.

Nice cycler for event shooter

Basically this cycler cuts recycle time by 50% which was still too slow for me because I need to reduce recycle time to 1sec for a smooth workflow (I often shoot at ISO 100 during daylight so need full flash power.) If you shoot events and need only half of your flash power this would be great accessory to have as it is extremely light and keeps your flash working for a very long time. The only issue I've encountered is with Pocket wizard TT5 transceiver, you can't keep it's antenna vertical ..well it's not really a problem as it doesn't really interfere with function.

The X flash accelerator is very easy to use -just hold the on/off button for 3 seconds and go. The accelerator works as advertised. It not only recycles fast for a longer time but helps the flash batteries last longer. It is small, compact and better than the larger belt ones with their cables. You can discuss the its performance with their support person.

Would a neck or shoulder strap attached to the camera body lugs interfere with this product? It looks like it would.
Asked by: Larry F. L.
I will surmise that it likely will. Depending upon what you are photographing, you may be able to successfully manage the strap and X Flash.I do not employ the camera neck strap on the camera body that employs the X Flash unit.However, looking at my second camera that does use the neck strap, but not the X Flash unit, I believe my opening sentence is correct. Personally, I do not like a neck strap. Most of the time. But, a friend that helps me at times likes the neck strap, so I usually leave it on. However, when I'm in a third world country, I do utilize the neck strap as a security situation.I really do like the performance of the X Flash unit.

Does this work on a 580 flash ?
Asked by: Mark G.
Yes, the 580ex and the 580ex II both have an external power port. It will work with others as well, any Canon on-camera flash with HV connector.

Will is work with the Macro Twin Lite MT-24EX?
Asked by: Dennis D.
I am not familiar with the product you suggested. Sounds like a question you need to have a photo store technician discover an answer for.
