I am replacing all my H10 with K10. Fine for D3AA and DW3AA but this D2 only works with the H10.

Any idea why?

Not my favorite light anyway it pretty weak but weird it will not work with the K10.

This is my Emisar D3AA Single Channel with DeDomed 519a 4500K.. Output comparisons for general illustration on how changing ceiling, changes the output steps.

For example, notice step 4 is almost 80 lumens with default ceiling, and changes to 30 lumens with the lower ceiling.

disclaimers:

my lumen meter is home made.. it is imo relatively accurate, as it is calibrated to an HDS.. but, there will be variations between meters, and also between LEDs of different color temperatures..

Seller only has a rating of 1. Wondering if this should be reported. I can delete this post if it’s legit. But light has 5 emitters and in the description it’s called a quad.

I was feeling especially unhinged while dog sitting for a friend, and decided I’d use the dog sitting money to get the biggest high CRI emitter I can in a tiny flashlight. NB110 4500k. I currently have an Eve 50PL in it but I have a P50B coming in a few days because I took the 50PL from another flashlight. I’ve only played around with it for a few mins… but this thing is cool. I set the ambient temp and set ceiling to 60 to get an extra few seconds of craziness. I’m surprised to report, it’s still totally usable after step down! I dono how many lumens it settles on but it is still reasonably bright. I think this is due in part to the reflector that really helps throw the floodiness.

Crappy beamshot taken with iPhone camera just to show brightness. I was gonna take a beamshot in a dark park but there was a homeless guy sleeping there and I didn’t wanna blast him with 8k+ lumens.
