  • good product

    posted by fnflores

    good quality product, great luminosity (please take care, do not see LED directly), easy to use, it is applicable for any Arduino LED project, it comes with a standard packing.
    Recommended for high luminosity LED projects (I did a Christmas light for home), also to test any Arduino library works fine!
    Use it! it is fun and really easy to use!
  • A good driver for LED 3W

    posted by evgenic

    I bought this driver for 3W Osram LEDs (SKU194296). With this driver - good brightness LEDs, although it is not the limit, because the LED's operating voltage of 3.9 V and operating current of 750 mA. The driver outputs a voltage 3.63 V and current 650mA. Thus the total power is obtained understated ... But I tried to connect the LED Cree Q3.Operating current 700mA turned to him and he shines much brighter (a feature of the LED Q3). The advantages of this driver could be considered that it is made in the closed case and sufficiently thick wire.
    I would recommend using this driver with LED Q3.Power same but higher brightness.
    All in all - a good driver for LED 3W (2.5W ~ real power is ~2.5W , but the LED is less heated). I found this driver only on the DX (for the presence of rare items - I love DX). I recommend to buy!

    The light is very bright and very low cost compared to what you'd find trying to buy something like this in the states.Easy to solder leads or wires to and can be chained together to make a very bright multi strip light.
    None
    I'm definitely going to be buying more like this one in the future.Might even do my whole house with LED's through DX.com

    * Very compcact * good build quality * easy to improve
    This driver is build on MC34063a base, so you can easily midfiy it, if you want to make dimminel light. All that you need to do, it's deolider 220 Ohm SMD resistor form the top of the board, and solider on ti's place in series 220 Ohm resistor and 5 KOhm potenciometr, and you get 3W led driver with variable current. But, if You ar intersted in usingi it on the lowest current you wil need to change Coil with bigger one, to prevent blinking
    Very good LED driverMust have for DIY projectVery cheap, about $1 per driver
  • Very bright for money

    Very solidly built and sized accurately so that it perfectly replaced the halogen bulb in fitment. Aluminum body seems very strong, and does not heat up hardly at all in use. Light output is very strong. Same as halogen, and brighter than an older 18 LED bulb I also own. The 6000k color also very close to halogen, and warm enough to read by comfortably.
    I am using this in my RV Trailer for reading lights, and it is more than enough that and as task lighting. Almost too bright for really close in fixture. I dont know how long the bulb will last over time, but am very happy with it so far.
    I am ordering 3 more today for the rest of the fixtures. These are much better than the older 18 led bulbs I have, and the color and build seems much nicer for use.
