  • Good little switches

    posted by seanv317

    Bought 6 of these to run lights on my truck,- 20A switches so will power almost anything you want them for.-comes with a built in light so I can find them at night.-work great for the price, on the shelf here in Canada there $5+
    I do alot of mods to my vehicles so will be coming back to get more.
    Great switch for anyone! easy to install in tight places too!
  • fine COB strip

    posted by Iceananas

    - good quality- comforatble warm white color- compact size
    Such high power led modules generate a huge amount of heat! only operate them with sufficient cooling!
    This COB module is quite good, but too expensive. Several sources sell similar modules for much cheaper. Maybe DX should check the price.
  • 3*7135 chips

    7135 chipsRegulatedMemoryReal output advertised
    This regulator drive out fairly steadily 1.4 amps. in max. mode.Exactly: 1.35 in high mode, 0.4 in middle, 0.6 in low (fluctuating in sos and fast strobe modes).I have put it, working together with a 16 mm alu base Cree R5 led in my Trustfire TR-801, and it bright now 25%-30% more than the original Cree Q5 led, giving a really flood light!According Cree data sheets, Cree R5 can hold up 1,5 mA, so this regulated circuit is perfect to this led. Other drivers that can only drive up 1000 Ma, will give 25% less light tan this.
    I recommend it
  • Cheap but usable.

    posted by LincKraker

    Price of course. ease of use.
    a bit long if you plan on using with arduino. if using with arduino I would actually buy SKU: 138396 ( http://www.dx.com/p/jl0525a-2-1mm-dc-power-female-jack-connectors-20-piece-pack-138396?rt=1&p=2&m=3&r=2&k=1&t=1&s=140327&u=138396 ) as they are shorter.Will probably use a dab of super glue to keep the plastic shell on the metal tip.
    Would I purchase them again? yes but for my purpose I will probably purchase the shorter tipped ones.
  • Good for charge your mobile

    posted by matolegin2

    Its easy to use, you can wirelesly transmit 5V max. 600 mA. I am using it with charging my mobile phone. You can connect receiver output directly to micro USB port of yopu mobile phone.Transmitter is supplied from adapater by 12 V (1A)
    Nice small coils, small PCBS, can be easy situated under the protection cover of mobile.
    When you need 500 mA current better use two devices.
