    Li-ion PT APEX headlamp

    I thought I would post some beam shots of upgraded APEX headlamps for others to compare when contemplating upgrades. This shot is of the Seoul Semiconductor P4 LED upgrade to an APEX. The Particular P4 used was a U flux bin and an SWO color bin. It also turns out that the Stock APEX in the...

    Li-ion PT APEX headlamp

    This may be if interest to current or perspective PT APEX users. Princeton Tec has recently within the last few months made changes to the materials and manufacturing methods of the housing.There is no visible difference in the housing but the results are the housing is more crack resistant...

    Li-ion PT APEX headlamp

    I have found that the APEX runs on a single Li-Ion cell very nicely. It doesn't stay in full regulation long but the low voltage protection circuitry in the cell doesn't surprise you without warning like it does when running 2 cells. I have been testing it out with an old worn out 18650 that...

    RGB led strip mood lighting - what value pot ?

    Usualy RGB is done using PWM. I think you will have a hard time geting the range of intensity and and precision of contrloe especially near the brighter end of the spectrum with a linear or audio pot. I would check out this website http://www.rgbled.org/ You can get a rather inexpensive RGB...

    Li-ion PT APEX headlamp

    I took the oportunity to measure the LED drive currents today when I was puting in a SS P4 and replacing the 5mm with some C0 color bin Nichia CS's. This was a different APEX headlamp than was used in my previous posts. The light being powered from 4 NiMH cells and the readings were taken with...

    Cree XR-E in a MagLed 2AA

    I am sure that I am not the first to do this but I got my P4 bined Cree XR-E's in the mail today and while playing with them I noticed that the deep reflector from my MagLed 2AA light worked great with it. I never liked my Mag because it had a very purple tint and did not seem to be very bright...

    A luxV in a PT Apex. Possible?

    The over all perceived brightness seems less to me for some reason. It is more focused with less spill, it may throw a bit farther but my so far I am not that impressed. With the optic it provided a good hot spot that had decent throw but also had a very wide and bright spill for illuminating...

    A luxV in a PT Apex. Possible?

    O ya I think it is a curent regulated buck converter. You probably need the battery voltage to be at the minimum a little higher than the VF of your LED. I run mine off a 2 cell Li-ion pack which reached up to 8.4V fresh off the cahrger and the converter is fine with that voltage but I would be...

    A luxV in a PT Apex. Possible?

    I put in an IMS 20mm reflector in my APEX. It required cutting 3~4mm off the front of the reflector to get it to fit. I also had to cut off the 2 little mounting bumps that help hold the optic retainer in place. I personaly think I prefered the optic over my reflector and will be changing it...

    Dorcy 1AAA SMJLED Mod ?

    Try looking around at old cables and wiring harnesses on old or broken electronic stuff. It should not be to hard to find something that will work. The specifics of the connector is not to crucial but rather the function it preforms. The Digikey one I listed is what I used and it works excellent...

    Dorcy 1AAA SMJLED Mod ?

    Hi I helped Vortechs solder in the sockets on his Dorcy AAA. The pins we used were similar to these Digikey part number WM2511-ND. You really are looking for any kind of crimp terminal that has a fully enclosed box for holding a lead without needing to be inserted inside the plastic multi pin...

    M*gLED take apart

    Good Job. I am very interested in what the maximum input voltage is that the converter can handle. Interesting about the Luxeon. Could they be having a special one made for them with custom leads?

    What would a bleeding-edge Shakelight be like?

    I agree that adding to many coils would cause the magnent to not pass through them at a decent speed but I have not yet seen a shake light that seems to aproach that point. All the ones I have played with have the magnent pass through with little precieved resistance. I have a lame shake light...

    What would a bleeding-edge Shakelight be like?

    If we are stuck on the idea of having a shake light then the best thing I can think of to improve it would be to use several sets of paralel coils so that each pass of the magnent will produce 3-4X the power. O and of course use a good led like a Nichia CS.

    What would a bleeding-edge Shakelight be like?

    If you are trying to make a gear driven generator on a budget then the quality and reliability will be terable. But a quality gear driven motor generator can be made out of metal gears and other high quality parts which should be very reliable. Remember you said you wanted a good quality light...

    What would a bleeding-edge Shakelight be like?

    I think the best way to improve the shake light is to do away with the shaking. I see it as a verry in efficient way to generate energy. The hand crank or squeeze generators yield much more energy for the effort put in to doing the work. The only advantage I can see to the shaking method is the...

    Need someone to install a new LED in my ultra G

    I have to admit I have not moded any Ultra G's but I have moded an older model infinity. I found that with the aluminum crimp broken off there was nothing to secure the circuit in and it was just floading in the head. Continuity did not seem to be as reliable as befor the crimp was removed. I...

    Need someone to install a new LED in my ultra G

    I would almost volenteer but I don't know how to seal it back up to the quality it with which it once was. You have to break off the aluminum crip around the circuit board in order to get it apart and then it is hard to seal it back up. You end up with a circuit board that can fall out during...

    How to remove the INOVA X1/X5t bezel.

    I did the freez pop disasembily on my x1 today and I cracked my lense in half during the second freeze. I believe that the desired pushing force actually comes from the frozen water in the battery tube. I worked very hard to get the head compleatly full of water and I think this was my down...

    Li-ion PT APEX headlamp

    They are Molex headers and conectors Digikey part numbers WM2700-ND, WM2011-ND, and the crimp spring terminals are WM2312-ND. They are probably not the best choice for this aplication but I had them on hand and they were small and polarized. I contemplated using 2.5mm dc barel jacks which I had...
