  • Really useful lights

    posted by ElectricEmu

    Easy to use: Obvious solder-lands where you can cut the strip to size. Polarity is clearly marked so it's easy to use any 12v power supply (I used a 15v supply for my second 3metres.)
    I used these to replace a couple of 35watt flouro (tube) lights. Two one-meter strips where I didn't really need excess brightness and three one-meter strips for the other. To match the light output of the original lights would probably need the whole 5 meters. I seem to be getting the equivalent light output of a 20watt tube from two and and a half meters. I will get more of these.
    Efficient, effective and easy to use. Oh and they're versatile too. I plan to get more of these to eventually replace all the lights here.
  • Powerful driver

    Powerful driver,Good selection of modes.
    I have installed this in to a custom built torch.The torch setup has a xml-U2 led driven by this driver and fed from an ultrafire red 2600mah 18650.All test results taken in high mode.Testing the output from the 18650 gives 4.00V and 4.00A giving a total battery draw of 16WTesting at the led gives 3.10V and 3.50A giving a led consumption of 10.85WCalculating these figures in to efficiency shows that 32% of the power is lost within the driver.This driver, but with selectable mode blocks (3mode 5mode 8mode etc) would be greatMust be fed from a good cell, when fed from a 14500 the max current is 2A not 4A.
    This XML-U2 build is really bright,I can live with the lack of mode memory and the extra disco modes.GOOD DRIVER!
  • 3*7135 chips

    7135 chipsRegulatedMemoryReal output advertised
    This regulator drive out fairly steadily 1.4 amps. in max. mode.Exactly: 1.35 in high mode, 0.4 in middle, 0.6 in low (fluctuating in sos and fast strobe modes).I have put it, working together with a 16 mm alu base Cree R5 led in my Trustfire TR-801, and it bright now 25%-30% more than the original Cree Q5 led, giving a really flood light!According Cree data sheets, Cree R5 can hold up 1,5 mA, so this regulated circuit is perfect to this led. Other drivers that can only drive up 1000 Ma, will give 25% less light tan this.
    I recommend it
  • Good driver for the modernization of the flashlight

    posted by Bezpieka

    Well done soldering.Good stabilization of the current at the specified range of supply voltage.Seamlessly cooperation with LED CREE XM-L2 U3
    Little short cable for flashlights witch variable focal length. When soldering thicker wires is needed soldering iron with temperature stabilization. There are likely to damage the driver.About 40 minutes of operation at full power on a single low-quality battery 18650
    Nice to use product for hobbyists that you can change parameter of your old flashlight.
  • good for the price

    It works, the programs, the speed, the intensity.
    the remote works from a good distance.
    the unit can control a lot of led strips (I connected it to 15 and it works fine.
    the controller is small.
    do the work at a good price.
    I needed a few when I got the led strips and it was what I was looking for.
    If you need it, buy it.
    a good price for a good product.
