*NEW* Nitecore EC4 & EC4S: (Possible) 2x18650, 2000 Lumens

Re: EC4S: 2x18650 2150lm

Understood. Too bad we can actually classify flashlights "standby" and "working", though. I like everything about this light except that, and wish it was BOTH working and standby like so many other flashlights (low drain like 5uA, 50uA even 100uA)

I agree mark6, if the EC4 had a lock out to remove all stand-by current, they would have a remarkable flashlight for all or any uses.

My car tires...is it ok to have a 2psi/day leak? I mean, I could just reinflate them every few days.

If a tire is losing 2PSI a day, as a collective, hopefully we'd get the leak repaired and hopefully, we'd take the time to have it repaired from the inside of the tire vs a simple tire plug. With that posted, I was responding to your quoted reposted comment and nothing more. This is why I suggested the purchase of a USB rechargeable flashlight. In my opinion, for a travel trip, a USB rechargeable flashlight would be ideal. Just saying, it's a big pain to always be charging a smart phone but what's a poor man to do?

What I was trying to do, and it seems I failed, was to point out how in life we have all kinds of details to attend to when one considers all that needs to be attended to while packing for and getting out the door of any sort of a travel trip. I just recharged the AAA batteries in the portable stereo T.V. headphones. That'll teach me not to put them on the charging dock before going to bed.

I understand that. It's not a big deal to charge, but it's nice to NOT have to. Like you just said, there is so much else to do in life, worrying about the SOC in 2 batteries in a flashlight is not always high on the list and it would be nice not to have to worry about that. Of course, us flashaholics have that as number 1 or 2 on the list

Thankfully my tires are fine. But hopefully Nitecore fixes their leak soon.

After this interchange, just to get me to shut up, they'll have to.

Just saying, the EC4S does have a lockout that makes it twelve month capable.

That is a nice feature. But if it's the same as the EC4, the lockout does not really change the parasitic drain. Like I mentioned earlier, I'll test that over the next few days. The 12 month thing is misleading. On month 11, what do you have? Nothing really worth using, so get them charged up! But yeah, that's a long time to let any light sit.

Looking forward to what your test data shows.

Has anyone noticed that the EC4S has a delay when turning it on? Mine takes about a second when I first push the button. It seems after it warms up the delay goes down.

Hi! Welcome to CPF......:welcome:

I just checked our EC4S and we don't have a start hesitation. If our unit is any sort of a standard, you may have an issue that should be addressed. I hope you can easily get the issue worked out.

Guys, i got big amazing surprise for you coming soon, stay tuned

 

[avca1998]

Thanks for the reply. I sent an email to Nitcore support and they said:

"we have tested and confirm there is a slight delay of approximately 0.5 second from the point you press the switch to the point the light actually comes on."

It doesn't really bother me that much. I just noticed that the delay in comparison to the EC4 I have.

I checked mine and there was no delay whatsoever. I have had lights do that in the past (Fenix LD22 comes to mind). I doubt it's the entire model; more likely isolated to a few here and there.

BTW, what have you guys done to me?!?! I'm starting to like the cool white on this light Even though the box says neutral, it's very cool. I wouldn't even say leaning towards neutral, but I guess not as blue as most others.

Re: EC4S: 2x18650 2150lm

Just a quick test while I was away for a few days:

EC4S
2x18650 NCR18650GA

Oct 8, 4PM: Cells charged to 4.17v then inserted into EC4S
Oct 9, 7AM: 4.15v
Oct 12, 4PM: 4.13v

.04v lost after 4 days!

So figure 4.17v > 3.69v after 4 weeks. That's pretty bad! I didn't lock it out, but from reviews I don't believe that helps; batteries must be removed. But I will do the test again locking it out and see what happens.

We've talked before how "it doesn't matter if you use it daily". Well, I don't...even if I did, I still wouldn't be comfortable with a light draining so quickly that I had to plan on recharging it before every trip or use when recharging wasn't an option.

the voltage settles down a bit even without load

btw you might wanna check your math

OOps! .89 not .69. Fat finger typist. That's still close to the point of recharging, for me.

I know they settle, so I let the cells sit for a bit after charging. They were actually borderline 4.18/4.17, so I called it 4.17v after settling to start. Bottom line still remains...this thing SUCKS BATTERIES, even with the error.

That was a nice deal! I went with amazon to burn some credits I had. I'll be out in the woods for a few days hunting and I'm taking this light...and of course a bag with 5 others! But I plan on using the EC4S a lot.

It was either this or the MH20NW that is also on discount at BG, but I decided on the EC4S as I already have ZL SC600 mk1 and I'm waiting for ZL to release SC600 mk3 to replace my mk1

I did just receive my 1/8 minus green filter sheet today. I removed the lens and traced it with a razor blade. This made the filter the perfect size and it sat right under the lens on the reflector. Very nice fit!! It doesn't do a lot, but just enough to let most of the light thru and give it a slightly more neutral tint. Perfect!!

Sounds great! So the lense is easy to remove? What kind of filter are you using? Are they expensive?

Really like the Ec4s. But Anyone with information if the set has regulated output ?
