  • Works perfect with my led bulbs at home

    posted by tuesskok

    it is small and this is verry important thing for me because i need to put it in the led bulb, i made my own led bulbs with this constant current source power supply driverit has a large working range - from 90V to 256V.
    I am verry happy with my own led lighting i made myself at home, it is cheaper than in the shop, it is energy saving.
    I bought ten constant current source power supply driver for all my led lights at home. If I need to make more light bulbs, I will buy again this power supply. I put ten one watts LEDs in one led bulb.
  • Good quality, 7.4W output, 8.6 watt consumption

    Small, good quality. High frequency output (LEDs will not flicker). Protected against too small resistance loading.Large input voltage range.
    While output power is around 7.4 Watts, consumption is 8.6 Watts (from 230V input voltage). This means 86% efficiency. Output voltage is vary depending on the loading to achieve almost constant current. In case of open circuit the output voltage is around 45 Volts.
    If You only need only 7.4 Watts and 86% efficiency, this product can be a good choice for You. You cannot use 10W 12V LED chips with this, because the lowest output voltage is higher than 12V
  • 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.
  • Cheap good 4x-6x 1W LED power supply

    posted by matutano6

    - Very cheap- Stable output- Good voltage: I meassured 7 units by my own between 21v and 24v. These voltage are very good for driving the voltage drop of 6 1W LED (sku 133086)- Good enough current regulation accurancy: suitable for 1W LED- The circuit PCB build seems to be of good quality
    I would like to test the power supply galvanic isolation from the AC line. A coil is present at the circuit, so its posibble the driver to be insolated, but I didn't test it yet. That feature of the power supply would be really nice!
    I was using 6 of these power supplies for more than a month for driving 6 1W LED (133086) each 10 hours a day and I'm really happy with the result.
  • Dimmable 13~18 LED

    posted by johnyconny

    Hello allI drive to this review that I've found that a dimmable LED driver is not in the web shop is indicated as dimmable?It is item number 174475I compared it seemed to article number 171146Look at the pictures.
    I've tested this with the LED. DIY 7W 2800~3200K 560~630LM Round COB LED Module (DC 21~24V) With these 3 LEDs 7w (141851)These LEDs are beautiful in color temparature.
    I am probably going to bying more.
