  • Best Driver I've found

    posted by bls123 on 12:43:23 G8T 09/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Small, lightweight and easy to modify for just about any use. Has very good current regulation that only varies 5-10ma at most over the total operating range. The units single resistor that sets the current level is easy to change. Input has a bridge rectifier so polarity independent and can be fed from either an AC or DC power source. Bridge rectifier diodes are easy to remove for greater efficiency when powering from a DC source. Uses a PT4115 chip. This makes the max input voltage 40VDC (or about 28V AC) so up to 10-11 LEDs in series can be powered (depending on which LEDs are used and the total LED voltage required of course). Input capacitor is only rated for 25V however so must be replaced for higher voltages.

    Cons: None (for me at least. Some have complained about the wires being too short, etc. but for my use I remove the wires, GU10 pins, bridge rectifier diodes and cut the board away where the diodes were to make it even smaller.

    Other: I buy a number of which ever (13553, 13555 or 13557) is least expensive at the time for projects and simply replace the resistor when a different current level is needed.

    Involvement Level: Expert (understands the inner workings)

    Pros: Small, light, perfect for small led-lighting projects. Is polarity indipendent.

    Cons: Short wires, had to solder new ones. Also, the big nail-like power connectors are a pain in the ass, had to desoder and solder simple wires

    Other: This product could be better if they had made the dim pin of the PT4115 more accessible. For a beginner is not easy to solder a wire to the small pin of a smd chip

    Involvement Level: Expert (understands the inner workings)

    Pros: Useful building block for driving LEDs from low voltage DC or AC. Based on well known PT4115 chip, the data sheet for PT4115 is available on the net. The board can be easily modified, series resistor changed for other output currents, there is a PWM input on the chip that can be used for dimming.

    Cons: The smoothing capacitor is rated at 25VDC. If you input 30VAC to the board the smoothing capacitor will be loaded beyond it's rating.

    Other: Very useful for my purpose, building special lamps for automobile use.

    posted by robertpbaxter on 12:44:46 G12T 10/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Really easy to remove and jumper the AC bridge diodes and solder to the dim pin.

    Cons: Only 2 out of 3 worked as they should have. One of them just pushed all the current on the input side to the output side. Fortunately I was using a current-limited supply and didn't fry my LEDs.

    Other: Small, easy to mod, works like a charm. Hate to bang them on quality but 1 dud out of 3 isn't a great ratio.

    Involvement Level: Expert (understands the inner workings)

    Pros: Great for driving 1watt LEDs in series. Can drive up to 4-5 Red LEDs in an automobile application (or 3-4 White LEDs)

    Cons: None really. Needed to remove the "MR16" posts, but no biggie. May provide FM radio interference, but see workaround below.

    Other: Perfect for driving 1watt LEDs

  • Efficient and flexible 1-9 LED 360mA

    posted by randytan123 on 11:23:31 G3T 03/03/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: many reviews that I read said that this LED driver is very easy to modify to add more features.
    For few months I was just using it to drive 1x 1 watt LED.
    But then I tried to experiment if it can support more LED in series if the input voltage is increased.
    To my surprise, it can light 9 LED successfully when I provided 32 V DC input. The current remained at 360mA through out the test with LED amount connected in series = 2 to 9.
    Thanks to the warning from other reviewer, I noticed that the capacitor used is only rated at 25 V (output capacitor), so I ran the unit for just 10 seconds to avoid unnecessary trouble when I drove 8-9 LED (26V- 29.5V).

    Cons: none that I can think of or observe.
    Be careful of the 25V rating of the capacitor, it may blow up the cap if you put voltage above 25 V for long period of time

    Other: very good in terms of price, performance and possible modification.
    no regrets in buying them

  • Excellent DIY LED driver

    posted by eboyer on 14:42:51 G10T 29/10/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Great price (especially the bulk rate)
    - High quality current output: I've used over a dozen of these drivers and they all provide a very constant current, and thus flicker-less LED lighting
    - Can be dimmed. The integrated circuit for this LED driver is the PT4115 LED controller, which contains a "DIM" input. Applying a pulse-width modified digital signal, or a variable DC voltage to this DIM input provides continuously-variable dimming of the LED. For more information on how to do this, see the PT4115 datasheet (it is very easy to read, so even a beginner DIYer should be able to do it).
    - Open-circuit protection: this driver will not be destroyed if it is not connected to a load when powered (this can happen to some LED drivers)
    - Thermal protection: the circuit will protect itself if it gets too hot
    - Highly efficient: the PT4115 is up to 97% efficient, so very little power is wasted
    - With a few modifications, it can output up to 1.2A at up to 30V, for a total power output of over 30W (this can be done by simply changing the resistor and inductor on the circuit. See the PT4115 datasheet for info on how to do this). This means that this driver can power LEDs up to 30W, although the inductor required for such high outputs would be a bit big for the circuit board.
    - Can be powered by either AC or DC voltage (but note that its maximum input voltage is NOT 40V, as stated in the product title. See my con section below for more info).

    Cons: - The maximum input voltage is NOT 40V, as is stated in the product title. The PT4115 IC can only handle a maximum of 30V, and the onboard capacitor is only rated for 25V, so the actual maximum voltage that you can apply to this LED driver is 25V DC (or 30V DC if you upgrade the capacitor to one with a maximum rated voltage above 30V). If you are powering it by an AC source then it will be even lower: the maximum AC input voltage is 18V, according to the PT4115 datasheet. This is because once an AC voltage is rectified and smoothed, its DC voltage will be higher than the AC voltage.

    Other: Excellent price and highly modifiable. Highly recommended for all 1W LEDs. Also has the excellent benefit of being dimmable with slight modifications.

    Involvement Level: Expert (understands the inner workings)

    Pros: Very cheap, do what it should, and easy to modify for your needs.

    Cons: Could have been better documented. Does not come in any form of antistatic packaging. Short leads, but you probably want to solder directyly to the board anyway.

    Other: This product is cheaper to buy just an inductor to build the device yourself.. at least here in Sweden. Very easy to modify for your needs, if you download the datasheet for PT4511 it's more or less built the same way as their typical application, so very easy to convert to 3W-version or make a dimmable version.

    posted by marcellaflamme on 10:06:03 G11T 29/11/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: I bought this driver for #13288 1W emitter for a costume. It works well, providing electric energy needed for my emitter to illuminate greatly. I wired the positive/negative incorrectly, but only realize afterwards, but it’s OK because it has a rectlefier (which means you can also use this AC/DC) It doesn’t get hot or anything, which was pleasant. I wired it so I had long leeds to my emitter, and kept the driver in my navel.

    Cons: The size is a bit tricky to accommodate in projects. The cap on the back is awkward. Soldering required, but you knew that. Short wires

    Other: Great price for a very polite product.
