I’m with Electric-Light on this one. Results 11 to 20 of The datasheet specifies 1.

The stated controlled output current is 0. Fundamentally it dxtasheet an adjustable resistor that is continuously adjusted by control circuitry that senses the voltage drop across a current sensing resistor that is in series with the current thru the adjustable resistor.

For a better illustrated version of these instructions, check out steps of Jon Gallant’s tutorial. With linear ballast, when line voltage goes up: You can even add Wi-Fi credentials with this method.

Dual J-FET Input Operational Amplifier

Sorry, but I think your initial premise is flawed. To use these, you can download dfu-util via the above link, then go to the command line and run dfu-util with one of the following commands.


Two different date codes of these lamps were energized simultaneously and they have a dramatically different dimming curve which means they dim totally differently alongside on the same dimmer because they have different integral ballasts. In post 11 you showed datashewt circuit that could imply a true linear regulator, but the capacitor implies an RC time constant of possibly 2.

Also use a scope to analyze circuit operation. Energy Star does not limit flicker in a meaningful way. I think it’s a concern that a product that has gone through a cost reduction engineering dwtasheet so drastic that the there’s nothing in common between the two products and they’re still allowed to bear the Energy Star logo under the same model number.

This is not like PWM dimming of a resistive load like an incandescent lamp.

Some Chinese designed LEDs are now using resistive series ballast – Page 2

All times are GMT I don’t have time to edit it shorter. A list of DFU commands is below.

They both have the exact same model number and there is no way to tell them apart. First, you’ll need to download and install the Particle driver.

Products are allowed go under a total gut change and bear Energy Star logo and recycle model without letting consumers know of difference. The output will be a big confusing mess, which is why most of the time you won’t need to use it. No limit on performance or durability deviation when operated above or below nominal voltage but within the ANSI tolerance. Plug your device into your computer over USB.

It looks something like this: Originally Posted by Electric-Light. Once the LEDs stabilize, then at constant current their power dissipation is constant. Originally Posted by gar. Your device MAC address is 1a: Then in post 17 you reference an ON datasheet that does not map to the device in your circuit of post The version he reviewed used a C capacitor, the version I evaluated used a C capacitor. Still less than what the LEDs are dissipating, but a very significant change, and one that needs to be understood by proper testing.

I agree with Electric-Light’s analysis of the lamp. We don’t recommend using these commands unless you’re very comfortable with the platform or unless you’ve been instructed to do so by Particle Support or an Elite community member.

The next problem is the needed power dissipation. I can only find via Google one Chinese datasheet that is somewhat readable in English.
