someone should try white lithium grease, as I asked before. that stuff won't wear off easily.

I'm also the finding the clip screws a little tricky to tighten fully

In another thread (Marketplace>Dealers>NitecoreClips) it was suggested 1.3 mm key fits these threads better than the supplied size.

This looks like a good choice for my first light. I dont' have the money to buy separate batteries (123's or 18650's) so i'm limited to a AA or AAA battery powered light.

Very nice review :)

I'd be willing to give it a shot. Now where to find white lithium grease... (and the quest for the perfect lubricant continues.)

Have you tried pure silicone oil to lubricate the piston o'ring? It should work very well, I use it all the time (not on a Nitecore, 'cause I don't have one yet), but on other o'rings that needs to be lubricated due to friction.

I have been thinking about getting this light but I have a question. On Nitecore's website as well as on 4seven's it says not to use lithium AA batteries. In fact it says this in large red letters on Nitecore's website. Does anyone know why? Will it damage the light? I read somewhere that lithium AA's put out a slightly higher voltage, about 1.7. Maybe this would mess with the processor. Any ideas? I have about 150 of these batteries stored up at home and it would be nice to be able to use them.

Hello Tim_B --


Welcome to CandlePowerForums !


:welcome:



To answer yer' question . . . .


(sigh)

You seem to have confused "Lithium Batteries" with

Lithium-Ion batteries.


Nite-Core's website sez: " (not Li-ion batteries) "


Your Energizer L91 Lithium Primary Cells are fine.

:thumbsup:

I got mine yesterday and I love it. I was also confused about the use of the Lithium batteries. So, I guess as long as they are just regular Lithium batteries they are fine, but if they are rechargeable that would make them Lith-ion and that would be bad correct? I will searching for the whole lithium information once I burn through the Rayovacs that I have.
I will also post some outside usage pics when it gets a few degrees warmer. But I walk my little pocket dogs last night. I tried the light for the first time in a wooded area I am used to my Fenix P2d, anyway I was really nervous that the D20 was going to be like a mini mag compared to P2D. But wow. I clicked the button and I was a happy camper. I love this little light so far. Mainly due to the size. I will get some pics and a short review here in a few days.

Yes, you are correct. You can use Energizer Ultimate Lithium (L91) cells no problem, as they are only 1.7v each. You CAN NOT use recharge lithium cells in this light! They are 4.2v each and the light would go :poof: in seconds if you used them.
The output on this light should be the same (if not more) than the P2D that you have. This light is around 120-130 lumens out the front on high.
I'm glad you enjoy it!

I just got my D20 R2 and to be honest, it doesn't look any brighter than my D10 and has more rings. At least to my eyes. The only thing it appears to do better is stay on longer. Still a nice light.
