Received my MR70, and I am so impressed with quality and simplicity of this multifunctional flashlight.
Also I can confirm that power bank function will deliver more power then stated in OP, but it will mainly depend on device you are charging,and how much power it need…
At least it has charging capability, but if it didn’t use the OTG cable, you’d need a full-size USB A port on it. But yeah, one more thing to keep track of.
I just finished testing of Rofis 26650 battery, and results are more then good !!
First of all, manufacturer of cell is definitely same as one of the best cells out there Littokala 5000mah and 5500mah. As you can see from the picture cells are identical, only wrapping is different.
And now the best part! After I completely discharged Rofis battery to 2.75V, I put it on a slow rate charge with 500mA on Zanflare charger, and got nearly 6000mAh !!!
I don’t know about you guys but this is the highest capacity high drain battery I have ever seen!!
A while back I communicated that sentiment to Rofis and they decided to offer NW versions in their new line of angle lights, so now their latest release, the R3 is available in either NW 5000K or CW6500K.
I also referenced the MR70 in my inquiry and it wasn’t excluded in their reply, so maybe they eventually will offer the a NW option for it too.
And now there’s yet another new light in the category of the MR70 that’s available in CW only: The Lumintop ODF30
So between the three, TC20, MR70 and ODF30, the TC20 is the only one currently available with a NW option.
You can have the same CRI at any temp, and CW LEDs are more efficient so you’ll get longer runtimes providing you cap the lumens at the same levels. I.e. an Emisar running at 1000 lumens in both CW and NW flavours will see the NW run out of juice first.
Thanks, I don’t recall ever reading any discussion of the heat or runtime thing of CW vs NW, just a lot about color rendering for NW.
Not saying it hasn’t been discussed, but I personally don’t recall anyone raving about a great High CRI cool white either. I do have a High CRI triple Nichia 219C R9050 in 5700K, and it’s a bit too cold for my liking, but it does have great color rendering.
I think deciding on a NW or CW is completely subjective to the users preference of light color, much more than a decision based on minor brightness, heat or runtime differences.
For example I’d gladly sacrifice a few lumens, a bit less runtime and a bit more heat to have NW. For someone who truly prefers a NW tint I doubt they would change to a CW because it “gives (edit:slightly) brighter light, cooler temps and longer runtimes”. JMTC
It’s why I prefer the 6500k Emisar D4 XP-L over the 5000k Emisar D4 XP-L in 18650 format. In 18350 use I prefer the 5000k as it doesn’t get red hot.
Tbh I don’t have many of the same lights in both NW/CW to compare heat handling but going by the Emisar it’ll be significant. I bet a 4000k Acebeam X80 would get pretty toasty compared to the 6000k stock light. With the warmer X80 being 2500 or more lumens less!
Thanks, that might explain all the crazy turbo amp draws I’ve been seeing. Anywhere from 4.16A, 6A and 8.1A. I wonder what it would draw with an unprotected 26650?
No one has really measured the lumens, so all I have to go on are the amp draws, and those need to be with a good unprotected high drain battery.
