    My new caving-light

    Hi majoetetaa07. Your English is better that my French so well done. Thanks for some of those sites, good on google translate which made it possible for me to read them, interesting. The main problem I see is still the switch, the covers do not seem to last long. I have done some changes to...

    How to test driver efficiency

    Thanks for that but what if the driver does not give out good DC or some sort of sine wave. I have four meters. 2 of which are good for voltage and the other two tie up with each other for current. I also have a bench power supply which is great as I can look at different voltage. Is is the...

    dx 4735 testing

    I dont know what the driver is as I have just picked up on this thread because of the efficiency question. I am interested in measuring the efficiency of several drivers but because the current is switched what is the most accurate way of doing this?

    Kayak Navigation Light

    This is not my area so much but each LED has a slightly different forward voltage so if you got just 2 LEDs and they had different voltage then one could take more current than the other. Probably not a problem if you are operating them well below the rated capacity other than you would have one...

    Kayak Navigation Light

    Check your local regulations. Strobe is for man overboard. I have used a strobe thinking it would stand out with lights from the city behind. It did not seem to make any difference to the boat that just about ran me down. I saw him coming but he got one hell of a fright when spotted me as he...

    Kayaking light help?

    Check on your local regulation! Although overall I only have to carry a flashlight to prevent collision local bylaws are often tighter. I used to go out a lot at night when my children were smaller. I have been out at 2am when the police launch has come over because they could not recognise the...

    KD SSC P7 Drivers - Whats wrong with them !

    I am not that up on all the ins and out of the electronics but I have just got one of these and had a play around with it. Very Very :( dissapointed the efficiancy is very poor on the lower settings and the switching between modes seems to be a low voltage issue rather than heat. I can run it at...

    Waterproof 4AA Battery Holder

    I am making some headlamps but want a battery holder. I do not want to get an otter box and put a battery holder inside as this makes it to big. There are a lot af lights out there with 4AA but I can not seem to get just the battery pack. The old petzl duo would be good. I have tried a surf...

    Need Advice on Waterproofing

    I would also recomend the heat srink with the internal glue. It is very good stuff, used for underground cables and joines exposed to the weather. You can get thin or thick wall heat skink depending upon the amount of physical abuse you expect. But I would not use a thicker one to cover the...

    Replacement of carbide lamps by LED lamps

    Hi Tobias, Thanks for all the info, keep it up. I have been having a small play around but only to the extent of fitting leds into an existing mining light. I have been using a DX 1917 which I found easy to cave with and it did not seem to raise too many complaints from others in the party...
