  • good cheap led driver

    posted by edmundszalite

    cheap, low heat, good quality of soldering, free space to solder additional resistor for more power.
    wold be nice to have IC connection diagramm for dimming. if any have more information about this driver please let me know.
    i made dimming by adding power MOSFET from computer mainbords CPU regulator so i can change otput power from 2w to 120w with potentiometer or through RC circut so having slow rise and fall of light.
    excellent driver for DIY applications
  • Quality LED driver

    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.
  • Wide range powerregulator.

    Rather small powerregulator for the high current and very usable in his reach, the VC AND CC helps to get the best out of high power leds and laserdiodes (!) (use of a antiparalleldiode is strongly advised)Althougt 5A is often an overkill for LD and LED this pc will work in its comfortzone and live as long as leds or even longer, when it can run cool
    It must be possible to use a ptc/ntc to protect the temperature of the led/LD when matched with the CC pot, have not calculated the right value but it can be done.So can it be used for TEC (peltier) but watch out, TEC elements often take morec than 5 amps/12V and below the right current the efficiency drops dramatically
    This unit has really many possible kind of uses, creative minds will recognize this.
  • Replacement

    posted by CraigH

    LED GU10 lamps have average to poor reliability. I have seen LED and PSU failures. These are a good replacement allowing a fix avoiding disposal of an expensive lamp. I have had to repair 15 lamps that I bought out about 36. Failures includes the PSU, and the LED.
    None really. They are what they are.
    A good cheap fix that allows you to keep the GU10 lamp in service for longer.

    The product has a small size and good price
    It seems that the nominal power of 3Watts is close to the limit of the circuit. After some minutes working the temperature of the lamp is quite high. Probably the high working temparature have reduced the life ot the driver/lamp.
