Questions about Fire Foxes FF5 HID

Voltage is inversely proportional to current. Meaning doubling the voltage halves the current.

Did I apply amps to number of cells correctly? I know when cells are in parallel, the amps are distributed. What I asserted is about cells in series. Is it the same with cells in series, each cell gives equal portion of the total amps?

In series configuration each cell will see the same current load. The Ah rating is unchanged as well. The difference is in the voltage, it’s increased per each cell’s value. If you have 4 li-ions like your VTc4 in series, they can handle 30A, and the voltage is 16.8v fully charged. In 4P, the current handling is quadrupled as is capacity, but voltage doesn’t change. I am thinking the FireFoxes uses a 2S2P cell configuration.

Unclear. In a 4 cell in-series flashlight drawing x amps, will each cell see
x amps
or
x/4 amps?

It will be the same across each-each will see the same current. It’s not multiplied. If the flashlight draws 15A, each cell deals with 15A. Either way, multicell configuration is best for high currents.

Thank you. My assumption was that total amps were divided (not multiplied) among the cells in series, as with cells in parallel. I greyed out the incorrect assumption in my first post.

So… where is this bad boy 15A flashlight? :sunglasses:

There are several single cell lights that draw 15A or more on turbo out there.

Put it this way a 30Q 3.6v and 3ah
4s1p (4×3.6v)x3ah=43.2watt hours
1s4p 3.6vx(4x3ah)=43.2watt hours
You can see that the lower voltage has to supply more current than a higher voltage for the same work. In series there is 1 current path so 1 current. Parallel there is multiple current paths so they are added together.

Hey guys, this is the first I’m hearing about HID… so how are these different or better than an LED thrower?

Tempted to get the 4300K just for the novelty of what i assume would be a powerful soft yellow beam?

Thanks!

4300K is pretty neutral. If you want warm, you dip below 4000K.

Classifying color temperatures into warm, neutral and cool is somewhat subjective, but this bloggy thing does a decent job, quoting below:

That’s great info thanks! For years I’ve bought lights solely on raw power but now I’ve been thinking how nice it would be to have a light that’s bigger for inside the house, going for a walk… Noctigon KR4 in 2000K is incoming (:

That sounds incredible

Yeah!! I got an Emisar from Hank and it’s one of my favorite lights in my humble collection. Someone on another thread told me that he got some 2000K LED’s. If you can believe it, I’ve never seen anything other than 6500K, unless you count the red, green, and blue led’s on my Nitecore headlamp

Hid lights are very different. They use an electric arc as a light source, and the light generated is very intense, more intense than an led. It’s also very small, which is great for throwing light long distances. The color temperature is also excellent with properly designed lamps. The downside is the electronics side, as they are more complicated, and hid have a warm up period from turn on before the light reaches full intensity (up to several seconds).

Wow that sounds amazing! Warmup time is no issue for me. Would the 4300k or 6000k be best? I’m learning toward the 4300. I wonder where the best place would be to order from, based on cost and how fast I can get this bad boy USA

Thanks!

How’s the HID bulb life? Can’t imagine I’d have it on more than like an hour a week max

The 4300k out of an HID is a little different than the 4300k out of an led. Not much. For the best you need close to 5000k as possible for the best beam color. Unless money isn’t an issue, the best place to buy something like this is China, where you can get a quality one for a good price. Stateside, if you can find one, good quality hid flashlights are really expensive, $500 and up. As far as longevity, the lamp will last a long time. In fact, if it isn’t abused or damaged by a faulty ballast, they will last years without degrading. I had HID lamps in my car last for 3 years easy and they’re the Chinese ones. Good quality drivers and ballasts make all the difference. A good bulb can be damaged or even underperform if not driven properly.

Hey, thanks for the great advice! Do you think ordering from Neal would be a good way to go? I’ve bought a lot of stuff from him and he’s great. So… if you were buying, would you get the 4300k option of the 6000k? Those are the only choices from neal. Or should I buy elsewhere, maybe to get something closer to 5000k?

I’ll prob order the accessory package too and I guess I need to get some batteries. What kind are you guys using?

Thanks!

I like the 6000k better

I did not expect that! What do you like better about it? Thanks for sharing knowledge with me
