Perfect mate! About the tints, I'm not sure as I've never had the choice between NW's, somewhere around 5000k to 5500k should be good, somewhere around the MM15 or the TN36 NW would be pretty much spot on. Shame about the parasitic drain, means I have to remember to tighten the tail cap prior to getting in the water or it will flood. Still definitely want the light though. I can transfer you money whenever you need it

I got this pretty much set to go. Got it with XM-L2 T6 4C's (4200-4500K), if that's ok. I'll pm you.

Hi guys,

I’ve recently got myself a Solarstorm DX4s. I wanted to turn it into a fill light with a massive beam spread. I search all over the internet and nobody makes a diffuser / silicone cap for a 55mm diameter flashlight. The closest I found was the Nitecore NFD60 which is a 60mm diffuser. It has high quality diffuser optics. I doubt it will stay on a 55mm head though. Willing to DIY one if I cannot find it sooner. Anyone could please share their setups for this?

Scotch Satin tape over the window. It wouldn’t become all flood but will become floodier. Add more layers if necessary. The better alternative is DC fix but I’m not sure where one can get that.

My gratitude to those who are willing and able to help others (in whatever way you can)! Being human is more than just existing for yourself. Smile

Thanks for your input. I forgot to mention. I’m going to bring it with me for underwater deep dives. Perhaps down to 40 meters (131.234 ft). The Scotch tapes might not stay on.

If you can unscrew the bezel and access the window, stick the tape on the inside of the window. It’s just an alternative if you can’t find something to work. I’ve used a latex glove as a difuser too. lol. All flood and even warms up the tint a bit.

I use KeepPower IMR5200mAh cells in mine and on high, the run-time is 3 hours.  When the cells are nearly depleted, it starts blinking over and over again, even after going to the lower mode. 

I have yet to use mine for diving purposes, but I’ll only get down to 25 meters, or possibly 30 meters if the DM allows it. Smile

Do you used KeepPower IMR5200mAh with or without protection circuit?

The blinking sounds annoying for sure… I’ll do a longer test on the 4000 mAh cells I have to hit the LVP level. Best cells for the mod light will be those 5200’s, either KP or EVVA, protected of course. Hoping the 5200’s won’t hit as high current draw, so will lose some output but gain runtime. This light’s driver is nothing too fancy – if it shows advantages for the spring bypass’s, then it’s not regulating very well. Of course might have to do with my resistor mod Wink.

Does the blinking mean, that the DX4s got a low voltage warning?

In case of it has low voltage warning or a shut off underneath 3V, why “protected” cells are necessary?

The current is not that high, that it will destroy the cell.
I believe the protection circuit in this case is only for low voltage protection or not?

I’ve bought two DX4S for diving with my girlfriend. I ordered it with these batteries:
https://www.banggood.com/4-x-26650-3_7V-5000mAh-Rechargeable-Li-ion-Batt...

On the first dive it worked fine, was amazed by the output of light in water with +- 3m visibility. But on the second time charging, 2 of the batteries don’t seem to charge and the other 2 looked to charge fine but on the dive it looked as i had very little light. My first guess is these batteries don’t do the job but the charger also could be the reason the batteries don’t work fine. Can anyone help troubleshoot so i can get diving with these lights again?

Thanks in advance!

Maybe check voltage of the 26650’s with a DMM? You bought a pretty cheap and crappy charger / battery combo, might be worth checking the charger is doing its job.

Stop using this charger and those cells, they are probably very low quality and could even be dangerous.

Li-ion batteries require more care then the Ni-MH we are all used to… and you don’t want to mess with them, especially in a 2S configuration. It is very recommended to use reputed brand name cells and charger.

Look for LiitoKala Li 500 charger and 5000 mAh 26650 for instance – although these are unprotected.
KeepPower protected 26650… there are others.
