led constant Customers Reviews

  • Good value

    posted by victordv

    Very useful for people who need small led driver, because it is small, works well only with device who is drowning ~650 +-50 mA. I use it for led checking, and presenting to other people, for me is OK. But I am sceptical when it is installed, how long will it work, because it is heating.
    Very dangerous because it does not have cover, it could electrocute you.
    Good for pros.
  • Great DIY repair for singe AA flashlights

    posted by QBranch

    Great to have around for repair of small single AA flashlights. I have four HUGSBY P31 lights (sku: 35078) and unfortunately 3 have failed. Found out that the emitter and switch are fine, so it must be the emitter board. So I found these on DX and ordered 5. These fixed all 3 of my P31 lights. BUT be aware that 2 of the 5 sent were 3 mode boards (Hi-Lo-Flash) and 3 were 1 mode (Off-On). The SKU stickers on the zip baggies were identical (128096). Note that the black boards with a larger baggies were 3 mode and the green boards with small baggies were 1 mode.
    Items got sent in a bubble mailer envelope and 1 emiiter got smashed.
    Great DIY repair board and to have some around for spare.
  • Very nice driver

    posted by FredericoRamos

    Great driver. Best of all I bought here in Deal Extreme. Steady 950mA readings. Do not become very hot, just warm.
    I use to drive 10 x 3W cree leds or 3 x 10W superleds. In both case the driver works perfectly and no overheat.
    Just buy it. With the shipping cost included, it is the best deal you will find out in the net. Just bought 5 or 6 I gess.
  • DIY your own led bulb :)

    posted by Dominik

    Small enough to put it in E27 DIY LED Light Bulb Casing with Focusing Optic (sku.13741). Remember to secure the bottom of the pcb board against short-circuit with the case - there are many soldering points and on the case you have more than 220V.
    If you want to make you own led bulb for small light spot it may be the right choice for you, but for bigger illumination I strongly suggest 3x1W version.
  • Works

    Works as described.Heat-sink build-in and works as protective cover, brilliant. Waterproof (not tested) but it's at the very least water-resistant :) It's cheap for being water resistant and free shipment.
    I would've liked a Ground-wire, but b/c of it's size I guess it's okay.
    It's definitely worth it, I use mine for a fan instead, but it still works like a charm.most satisfied.
