  • Quality LED driver

    posted by Lymatas

    This LED driver (power supply) is built very well. It is water resistant and designed to use with outdoor LED lightning. Dimensions are quite small. Recommended to everyone.
    This water resistant LED driver (power supply) could be more powerful with the same body dimensions. This LED driver (power supply) is built very well. It is water resistant and designed to use with outdoor LED lightning. Dimensions are quite small. Recommended to everyone.Nothing more to say.
    If you need water resistant LED driver (power supply), like this one - buy. Recommended to everyone.
  • Perfect for small projects

    posted by RacerXGT0

    Excellent price, very small size and build quality looks good.
    Drive 3 x 1watt LED's in a series exactly.
    I live in the USA so the 120 volt A/C color coding on this unit is setup for for European spec. All I did was match the HOT and NEUTRAL lines accordingly.
    USA: Black = Hot, White = Neutral
    EUR: Brown = Hot, Blue = Neutral
    This is great for small projects, though if building a multiple LED project with more than 3 LED's, better order more!
    This little LED driver is a winner, allows you to build very bright LED lighting for your home at a low price.
  • Great for DIY lights

    Its sealed so no need to worry about electrocuting yourself on components at mains voltages. Mounting lugs to attach it to your housing.
    I used two of these to under drive twenty 3 watt LEDs in a florescent light housing.It would be nice to have 20w drivers that can drive four 5 watt LEDs or two 10 watt LEDs, so I had less soldering to do.
    Great easy to use driver for twenty 1 watt LEDs (10S2P) or to under drive ten 3 watt LEDs.
  • Works well but not cheap

    posted by yrnkrn

    Works well. Can drive eight, nine, ten, eleven Cree XM-L at 2100mA. Price is not cheap at $25. In fact the 80W version http://www.dx.com/p/2-5a-80w-power-constant-current-source-led-driver-85-265v-47307 supplies 2.5A instead of 2.1A but costs two dollars less. Go figure.
    Output wires are too thin for this current. Replace them before using the driver. The wire hole size in the PCB is OK and can accept thicker wire.
    The 80W driver http://www.dx.com/p/2-5a-80w-power-constant-current-source-led-driver-85-265v-47307or the 50W driver http://www.dx.com/p/50w-led-driver-circuit-input-85-265v-output-22-26v-2300ma-42805are better deals.
  • Best choice repairing LED bulbs

    posted by MicroWizard

    This one is the most _durable_ LED driver I have seen. (Thanks to the VIPer22 controller circuit.)I have a lot of defective LED bulbs ranging 6*1W - 10*1W. Most of them are dead because the driver circuit was blown.This driver works well. No one died yet.
    All other type of LED drivers used to make fire. The ones which have two small yellow transformers are the worst. They usually blow up one or two LEDs first. After replacing LEDs - and a week of peace - they usually blow up itself. Replacing them with this ugly red part. The problem is solved for a long time.
    Don't waste time and money buying various 6-7-10*1W 330mA LED drivers. This type does work, others often fails.
