NiZN - WOW, Nice!

LED Flashlights – General Info
1

Alright, I got a pack of nice NiZN batteries shipped up to me by Match, and decided to do a short round of testing. The light I chose for this little test is the Crelant 7G1, the only pseudo-premium light I own. Not so much for quality, but it's the only multi-mode AA light I own, and the only AA light I have that's designed to take 14500s.

Anyways, beamshot comparisons first, NiZN is on the top, NiMH is on the bottom.

Pics are comparable, taken at 1/40th second, F4.0, ISO 100, 28MM focal length from the same distance. It's slightly difficult to ascertain here, but the NiZN is the brighter of the two. The histograms from the original pictures definitely confirms it.

Here's the nice thing - there's a nice current draw decrease for the voltage boost from the NiZN.

Batteries:

Rayovac "Hybrid" NiMH, 2100mAh claimed. Voltage 1.26V, draw 1.55A

PowerGenix NiZN, 1500mAh claimed. Voltage 1.8V, draw 1.15A

Nice boost, and it really shouldn't affect runtime too much either.

Wow, that Crelant 7G1 looks pretty sharp. This also makes me want to get some of them PowerGenix NiZN batteries even more. Undecided

Yup, it seems like the NiZn are just a step between eneloop and 14500's.

And like Fishinfool said, that crelant is a dang nice looking torch!

A little step I would say. The difference is not so big in my opinion.

BTW, sleek design :love:

UPDATE: what about safety? Or nothing to worry about? (comparing to Li-ion batts or NiMh)

i will take shots with my trustfire S-A2. in this flashlight it is the difference between night and day. a 1.2/1.5 is incredibly dim on this flashlight, as it probably knows its now a AA and not a 14500. go to Ni-zn and its almost as bright as it was with a 14500!

i noticed these things a while back but have not had time to do thorough testing and reviews

I did put up some NiZn numbers for some of my AA lights here are the Trustfire R5-A3 numbers. These are lux values at switch-on

Trustfire R5-A3 High 14500 1630

Trustfire R5-A3 High AA NiMH 650

Trustfire R5-A3 High NiZn 800

i havent tried the r5-a3. i just ordered another (this time from manafont) for my own personal collection lol

not selling this one if i can help it

Thanks all, it's also really nice to have a working multimeter back. I'd say there's a 20%-ish boost when examining the EV charting of the histogram and the current draw should mean runtimes reasonably close to the manufacturer's.

The only problem I have is with the torch itself - ALL the output levels are boosted, including the low. It's a slick torch, but a 12-13 lumen low just ain't that low. Thankfully, I bought it at wholesale from a local reviewer. I'm not sure I'd pay full retail even if the quality is good.
