    Nitecore D4 burnout, anyone else ??

    I eventually found an Ebay vendor who sold lots of 10 of the burned out FET Q8. I replaced it and the burned 0.5 ohm resistor on the first cell channel. The unit still failed to work correctly, the charge indicators showed charging going on on slot 1 with no battery inserted. Clearly some hidden...

    Nitecore D4 burnout, anyone else ??

    I'm not sure if it's under warrantee but frankly I don't tend to bother doing that with OS purchases, from past experience has not be worthwhile. So I'll be doing DIY repair if I can be sure what the burned transistor is. I think there may be others around here with faulty D4's, and we can pool...

    Nitecore D4 burnout, anyone else ??

    Hi other flashlight addicts. I bought a Nitecore D4 last year and it has been a good charger, but about a week ago it started playing up while charging normal NiMh cells. It now stops charging after a minute or so and the LCD screen goes blank till you cycle the power... I opened it up and...

    Convert Pelican Dive light to LED?

    I've ordered another type of BA15S style white LED lamp, supposedly it has more output and has a 12V-24V driver (yes I know more output is more heat). I just figure that if I am to play around with the LED retrofit idea I may as well push it a bit further. The lamp is this one...

    Convert Pelican Dive light to LED?

    Inserting a couple more (I'll try the insert image tool again). EDIT: Tried and failed again, so used Image Shack links. Still not done much about adding a driver, but I have found a tiny one meant for 12V down lights in my parts box. It also came from DX some time back for another LED lighting...

    Convert Pelican Dive light to LED?

    My posting permissions show 'You may not post attachments' so perhaps I'm just forbidden. No doubt this is to reduce spam or something, but it's not helpful right now. :) See if this works, I just pasted the links below rather than used the link tool in the message editor... Let me know if they...

    Convert Pelican Dive light to LED?

    I've completed step one of the test of a LED conversion. I've bought a LED 'tail light' from DX and had a play at fitting it to the King Pelican. Turns out to be relatively easy as the base diameter and locking lug positions are a match. A mod is needed to the lamps base contact, and the main...

    Convert Pelican Dive light to LED?

    Interesting debate, I agree that incandescent lamps don't care about some heat. Given that most of the energy from the incandescent lamp is lost in heat, the fitting still has to bare it and dissipate it I think (or melt). So I'll not give up hope just yet as there is a bit of metal in the...

    Convert Pelican Dive light to LED?

    I joined CF forums because of a similar problem and looking for lamp info. The Pelican King Lite is a very rugged waterproof housing and with 8D's fitted (or 2x1800mAh 3S LiPo in mine now) they would run a LED head for days. The two position switch could be used for two LED arrays or switching...
