PS Audio Discussion Forum

Paul, when i read the word “ultracapacitors”, I knew I had to ask you this non-audio question.

I am a former Police Officer and have always had the best of Flashlight equipment. (I bought the best because my safety does not have a price tag).
Maglight Rechargeables   215 Lumens for regular patrol
Surefire 8AX Commander (small) 110 Lumens for mouting on Duty-belt
and even a rescue lantern ...a Streamlight LiteBox Rechageable Lantern Flashlight (6V, 12Ah sealed lead acid operates up to nine hours per charge)

Well, there is a new light on the market claiming to use ultracapacitors and that their engineers have found a way to regulate the discharge of power, such that it has 4 power setting from 90 Lumens to as much as 270 lumens, AND, It recharges in 90 seconds - because there are no batteries, just the ultracapacitor.
FlashPoint™ Power Technology utilizes environmentally friendly ultracapacitors to quickly load and unload energy without a chemical reaction

Does this sound reasonable?

It’s $200 price tag is not unexpected (High-End flashlights for men who want real flashlights)

I am going to ask our chief of BS busting, Bob Stadtherr, to take a look but from everything I can see it looks legit.  These devices have nowhere near the energy density of a lithium ion battery (about 25 times less per pound) but then a flashlight doesn’t need so much so maybe this will work.

Pretty cool actually.

I work for a small company and we have just produced a piece of instrumentation which uses an “ultracap” for short term high amperage supply. The overall power requirement on this instrument is less than 15 amps at 120 vac but there is a resistance heater that requires 35 amps for about 30 seconds out of 5 minutes. We use the ultracap to supply this power and recharge it during its off-duty cycle. The thing is amazing, the only limit (almost) on its charge and discharge rate is the power supply and wiring. I think that they are rated at more than 100,000 charge/discharge cycles.
But as Paul said their energy density is still lower than Li batteries. I can see them being used in more and more future applications.
No I don’t sell these things but I do find them really cool!

Washington D.C. has a bus that recharges at every stop with ultracapacitors.

I like the lithium-air batteries.

I did not get this light yet but I picked up a great one for looking behind that rat’s next of Audio wiring! (Surefir Lumamax LX2 200 Lumen)

5.11’s new Light for Life duty flashlight is powered by revolutionary technology that lets it recharge in 90 seconds.

If you pick up 5.11’s new Light for Life UC3.400 and ask a company rep what makes it different from the hundreds of other flashlights on the market, you’d better have some time to listen to the answer. The Light for Life is really different.

Almost all flashlights on the market today use chemical batteries as a power source. The Light for Life uses an ultracapacitor system.

Ultracapacitors have been around for about 15 years. They are energy storage devices that charge very quickly and discharge almost instantly. So until now about the only practical use for an ultracapacitor in a consumer product was in the flash systems of digital cameras.

To make an ultracapacitor suitable for a flashlight, engineers had to find a way to regulate the discharge of power. And that’s exactly what the team at Ivus Energy Innovations has managed to do. Using Flashpoint Power Technology—a combination of computerized circuitry and an ultracapacitor—Ivus developed a power source suitable for a duty light.

At first the engineers at Ivus wanted to make their own line of duty flashlights, but they soon realized they lacked the marketing expertise to crack the law enforcement and military markets. Consequently, Ivus CEO David Alexander approached 5.11 Tactical.

5.11 CEO Dan Costa had been previously approached by other flashlight makers who wanted 5.11 to market their product. But he didn’t really like any of them. “They just didn’t meet our mission statement,” he says.

According to Costa, 5.11’s mission statement is to make products that “exceed the needs” of its law enforcement and military customers. When Costa saw the Ivus flashlight prototype, he immediately realized that its technology could be very useful for 5.11’s end-users.

5.11 licensed the Flashpoint Power Technology, then it went to work making a flashlight. The first step was to hold development meetings with more than 1,000 law enforcement officers and ask them what they thought. They gave 5.11 advice on the shape of the flashlight head, features they wanted to see, the positioning of the switch, and other concerns.

The result is the Light for Life UC3.400, an 11-inch, 1.75-inch diameter, hexagonal head duty light. The Light for Life operates in three modes: standard with 90 lumens of output, burst with 240 lumens of output, and a 270-lumen strobe. Runtime in standard mode is about 60 minutes with an additional 30 minutes of reserve.

But what really makes the Light for Life different is the Flashpoint Power Technology. The following is a list of some of the major benefits of this innovative power system:

•The light charges from dead flat to full charge in 90 seco

But what really makes the Light for Life different is the Flashpoint Power Technology. The following is a list of some of the major benefits of this innovative power system:

•The light charges from dead flat to full charge in 90 seconds.
•If it were charged once a day it would last for 50,000 days—that’s more than 135 years without degradation of the power source, hence the name “Light for Life.”
•Because it has no batteries, the Light for Life weighs 16 ounces, roughly half as much as a standard duty light.
•Flashpoint Power Technology is environmentally friendly because it eliminates the need for disposable or rechargeable chemical batteries and contains no heavy metals.
In addition to these benefits, 5.11 says the light will save end-users money because they don’t have to buy batteries or replacement parts. The Light for Life’s LEDs are rated for 50,000 hours.

The 5.11 Light for Life duty flashlight is expected to reach the market in February. Price has been set at $169.99, including a 12-volt DC car charger. The light has a limited lifetime warranty.

My brother bought that ultra-capacitor flashlight and confirmed the 90 second recharge as well as the lumen output. Now he won’t stop talking about it…...
