Re: Noctigon Meteor D4
Stepdown
The step down is very aggressive. This is good for protecting you from heat, but perhaps a bit too aggressive when it comes to how low it goes. One reviewer on BLF tested it and after 30 seconds on VTC6 it had stepped down to something like 300 lumens, but on an Aspire 18350 it had only stepped down to 1400 lumens. Basically the extra heat from the 18650 caused the temp sensor to kick in faster and overdo it.
On the upside, due to the ramping it's very easy to ramp back up if the temp sensor brought output down too far. My guess is the light can probably do 1500 lumens sustained for an extended period of time if you handhold it, and perhaps do not start at max turbo.
Slippery grip
Do you carry this light in a pocket, but hate the lack of knurling? ... simple solution is to add something to improve the grip. I installed Talon Grip Tape from Amazon on mine. Adds very little bulk and turns a slippery light into my grippiest. Feels great in the hand too. I highly recommend it for this light.
Its been in pocket at work and at home when carried yes, if i had a clip option but tapped for it............would be a winner(not into clip on clips at all). Thats a great idea with grip tape, it is a slipy feel/body...........but still nice to hold in hand.
Yes step down is aggressive but the head heat is still almost too much to bare (fine holding body but i like to get a better idea of the heat before i trust the step downs). Now even with the aggressive step downs, it is still toasty before it settles to a lower output and brings the temp under more control.
Cell used will sure make a difference, i have tried a vtc6 and 30Q only, if I used a 10a cell.....................probably hold out a bit longer. I have found though with even larger 18650 lights, 1000lm is too much to ask after 2 or 3mins, even 600lm is too much after 10m or so. Even a HDS 200lm gets quite warm after 10 + mins.
But i accepted before i got the D4 its not about running it for any length of time at full output, more for super short blasts and use the lower ouputs for actual general uses. I have said before, i can pretty much live with 200lm or less(most uses at work are around 150 as one example). At home, at night 20 or 30lm will do...............more is always fun though
Off to check some grip tape! cheers
